1 INDICATIONS AND USAGE Hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets are indicated for the management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. Hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets contain hydromorphone, an opioid agonist, and are indicated for the management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. ( 1 ) Limitations of Use ( 1 ) Because of the risks of addiction, abuse, and misuse with opioids, which can occur at any dosage or duration ( 5.2 ) , reserve hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets for use in patients for whom alternative treatment options [e.g., non-opioid analgesics or opioid combination products]: Have not been tolerated or are not expected to be tolerated, Have not provided adequate analgesia or are not expected to provide adequate analgesia Hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets should not be used for an extended period of time unless the pain remains severe enough to require an opioid analgesic and for which alternative treatment options continue to be inadequate. Limitations of Use Because of the risks of addiction, abuse, and misuse with opioids, which can occur at any dosage or duration [see Warnings and Precautions (5.2) ] , reserve hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets for use in patients for whom alternative treatment options [e.g., non-opioid analgesics or opioid combination products]: Have not been tolerated or are not expected to be tolerated, Have not provided adequate analgesia or are not expected to provide adequate analgesia. Hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets should not be used for an extended period of time unless the pain remains severe enough to require an opioid analgesic and for which alternative treatment options continue to be inadequate.

12.1 Mechanism of Action Hydromorphone is a full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of hydromorphone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with morphine. Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression. The precise mechanism of the analgesic action is unknown. However, specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and are thought to play a role in the analgesic effects of this drug.

Dosierung und Verabreichung

2 DOSAGE AND ADMINISTRATION Hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets should be prescribed only by healthcare professionals who are knowledgeable about the use of opioids and how to mitigate the associated risks. ( 2.1 ) Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals. Reserve titration to higher doses of hydromorphone hydrochloride for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks. ( 2.1 , 5 ) Many acute pain conditions (e.g., the pain that occurs with a number of surgical procedures or acute musculoskeletal injuries) require no more than a few days of an opioid analgesic. Clinical guidelines on opioid prescribing for some acute pain conditions are available. ( 2.1 ) Initiate the dosing regimen for each patient individually, taking into account the patient's underlying cause and severity of pain, prior analgesic treatment and response, and risk factors for addiction, abuse, and misuse. ( 2.1 , 5.2 ) Respiratory depression can occur at any time during opioid therapy, especially when initiating and following dosage increases with hydromorphone hydrochloride. Consider this risk when selecting an initial dose and when making dose adjustments. ( 2.1 , 5.3 ) Discuss availability of naloxone with the patient and caregiver and assess each patient's need for access to naloxone, both when initiating and renewing treatment with hydromorphone hydrochloride. Consider prescribing naloxone based on the patient's risk factors for overdose. ( 2.2 , 5.2 , 5.3 , 5.4 ) Initiate treatment with hydromorphone hydrochloride oral solution in a dosing range of 2.5 mL to 10 mL, 2.5 mg to 10 mg, every 3 to 6 hours as needed for pain, and at the lowest dose necessary to achieve adequate analgesia. Titrate the dose based upon the individual patient's response to their initial dose of hydromorphone hydrochloride oral solution. ( 2 , 5 ) Initiate treatment with hydromorphone hydrochloride tablets in a dosing range of 2 mg to 4 mg, orally, every 4 to 6 hours as needed for pain, and at the lowest dose necessary to achieve adequate analgesia. Titrate the dose based upon the individual patient's response to their initial dose of hydromorphone hydrochloride tablets. ( 2 , 5 ) Do not abruptly discontinue hydromorphone hydrochloride in a physically-dependent patient because rapid discontinuation of opioid analgesics has resulted in serious withdrawal symptoms, uncontrolled pain, and suicide. ( 2.7 , 5.14 ) 2.1 Important Dosage and Administration Instructions Ensure accuracy when prescribing, dispensing, and administering hydromorphone hydrochloride oral solution to avoid dosing errors due to confusion between mg and mL, which could result in accidental overdose and death. Ensure the proper dose is communicated and dispensed. When writing prescriptions, include both the total dose in mg and the total dose in volume. Instruct patients and caregivers on how to accurately measure and take or administer the correct dose of hydromorphone hydrochloride oral solution. Strongly advise patients and caregivers to always use a graduated oral syringe or measuring cup, with metric units of measurements (i.e., mL), to correctly measure the prescribed amount of medication. Inform patients and caregivers that oral dosing devices may be obtained from their pharmacy and to never use household teaspoons or tablespoons to measure hydromorphone hydrochloride oral solution. Hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets should be prescribed only by healthcare professionals who are knowledgeable about the use of opioids and how to mitigate the associated risks. Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals [see Warnings and Precautions (5) ] . Because the risk of overdose increases as opioid doses increase, reserve titration to higher doses of hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks. Many acute pain conditions (e.g., the pain that occurs with a number of surgical procedures or acute musculoskeletal injuries) require no more than a few days of an opioid analgesic. Clinical guidelines on opioid prescribing for some acute pain conditions are available. There is variability in the opioid analgesic dose and duration needed to adequately manage pain due both to the cause of pain and to individual patient factors. Initiate the dosing regimen for each patient individually, taking into account the patient's underlying cause and severity of pain, prior analgesic treatment and response, and risk factors for addiction, abuse, and misuse [see Warnings and Precautions (5.2) ] . Respiratory depression can occur at any time during opioid therapy, especially when initiating and following dosage increases with hydromorphone hydrochloride oral solutions and hydromorphone hydrochloride tablets. Consider this risk when selecting an initial dose and when making dose adjustments [see Warnings and Precautions (2.1 , 5) ]. Initiate treatment with hydromorphone hydrochloride oral solution in a dosing range of 2.5 mL to 10 mL, 2.5 mg to 10 mg, every 3 to 6 hours as needed for pain, and at the lowest dose necessary to achieve adequate analgesia. Titrate the dose based upon the individual patient's response to their initial dose of hydromorphone hydrochloride oral solution [see Dosage and Administration (2) and Warnings and Precautions (5) ] . Initiate treatment with hydromorphone hydrochloride tablets in a dosing range of 2 mg to 4 mg, orally, every 4 to 6 hours as needed for pain, and at the lowest dose necessary to achieve adequate analgesia. Titrate the dose based upon the individual patient's response to their initial dose of hydromorphone hydrochloride tablets [see Dosage and Administration (2) and Warnings and Precautions (5) ] . 2.2 Patient Access to Naloxone for the Emergency Treatment of Opioid Overdose Discuss the availability of naloxone for the emergency treatment of opioid overdose with the patient and caregiver and assess the potential need for access to naloxone, both when initiating and renewing treatment with hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets [see Warnings and Precautions (5.3) ]. Inform patients and caregivers about the various ways to obtain naloxone as permitted by individual state naloxone dispensing and prescribing requirements or guidelines (e.g., by prescription, directly from a pharmacist, or as part of a community-based program). Consider prescribing naloxone, based on the patient's risk factors for overdose, such as concomitant use of CNS depressants, a history of opioid use disorder, or prior opioid overdose. The presence of risk factors for overdose should not prevent the proper management of pain in any given patient [see Warnings and Precautions (5.2 , 5.3 , 5.4) ] . Consider prescribing naloxone if the patient has household members (including children) or other close contacts at risk for accidental ingestion or overdose. 2.3 Initial Dosage Initiating Treatment with Hydromorphone Hydrochloride Oral Solution or Hydromorphone Hydrochloride Tablets Hydromorphone Hydrochloride Oral Solution Initiate treatment with hydromorphone hydrochloride oral solution in a dosing range of 2.5 mL to 10 mL, 2.5 mg to 10 mg, every 3 to 6 hours as needed for pain, and at the lowest dose necessary to achieve adequate analgesia. Titrate the dose based upon the individual patient's response to their initial dose of hydromorphone hydrochloride oral solution. Hydromorphone Hydrochloride Tablets Initiate treatment with hydromorphone hydrochloride tablets in a dosing range of 2 mg to 4 mg, orally, every 4 to 6 hours as needed for pain, and at the lowest dose necessary to achieve adequate analgesia. Titrate the dose based upon the individual patient's response to their initial dose of hydromorphone hydrochloride tablets. Conversion from Other Opioids to Hydromorphone Hydrochloride Oral Solution or Hydromorphone Hydrochloride Tablets There is inter-patient variability in the potency of opioid drugs and opioid formulations. Therefore, a conservative approach is advised when determining the total daily dosage of hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets. It is safer to underestimate a patient's 24-hour hydromorphone hydrochloride dosage than to overestimate the 24-hour dosage and manage an adverse reaction due to overdose. In general, it is safest to start hydromorphone hydrochloride therapy by administering half of the usual starting dose every 3 to 6 hours for hydromorphone hydrochloride oral solution; and every 4 to 6 hours for hydromorphone hydrochloride tablets. The dose of hydromorphone hydrochloride can be gradually adjusted until adequate pain relief and acceptable side effects have been achieved [see Dosage and Administration (2.5) ] . Conversion from Hydromorphone Hydrochloride Oral Solution or Hydromorphone Hydrochloride Tablets to Extended-Release Hydromorphone Hydrochloride The relative bioavailability of hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets compared to extended-release hydromorphone is unknown, so conversion to extended-release hydromorphone may lead to increased risk of excessive sedation and respiratory depression. 2.4 Dosage Modifications in Patients with Hepatic Impairment Initiate treatment with one-fourth to one-half the usual hydromorphone hydrochloride starting dose depending on the degree of impairment [see Use in Specific Populations (8.6) , and Clinical Pharmacology (12.3) ] . 2.5 Dosage Modifications in Patients with Renal Impairment Initiate treatment with one-fourth to one-half the usual hydromorphone hydrochloride starting dose depending on the degree of impairment [see Use in Specific Populations (8.7) , and Clinical Pharmacology (12.3) ]. 2.6 Titration and Maintenance of Therapy Individually titrate hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets to a dose that provides adequate analgesia and minimizes adverse reactions. Continually reevaluate patients receiving hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets to assess the maintenance of pain control, signs and symptoms of opioid withdrawal, and other adverse reactions, as well as to reassess for the development of addiction, abuse, or misuse [see Warnings and Precautions (5.2 , 5.14) ] . Frequent communication is important among the prescriber, other members of the healthcare team, the patient, and the caregiver/family during periods of changing analgesic requirements, including initial titration. If the level of pain increases after dosage stabilization, attempt to identify the source of increased pain before increasing the hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets dosage. If after increasing the dosage, unacceptable opioid-related adverse reactions are observed (including an increase in pain after a dosage increase), consider reducing the dosage [see Warnings and Precautions (5) ] . Adjust the dosage to obtain an appropriate balance between management of pain and opioid-related adverse reactions. A supplemental dose of 5 to 15% of the total daily usage may be administered every two hours on an as-needed basis. 2.7 Safe Reduction or Discontinuation of Hydromorphone Hydrochloride Oral Solution or Hydromorphone Hydrochloride Tablets Do not abruptly discontinue hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets in patients who may be physically dependent on opioids. Rapid discontinuation of opioid analgesics in patients who are physically dependent on opioids has resulted in serious withdrawal symptoms, uncontrolled pain, and suicide. Rapid discontinuation has also been associated with attempts to find other sources of opioid analgesics, which may be confused with drug-seeking for abuse. Patients may also attempt to treat their pain or withdrawal symptoms with illicit opioids, such as heroin, and other substances. When a decision has been made to decrease the dose or discontinue therapy in an opioid dependent patient taking hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets, there are a variety of factors that should be considered, including the total daily dose of opioid (including hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets) the patient has been taking, the duration of treatment, the type of pain being treated, and the physical and psychological attributes of the patient. It is important to ensure ongoing care of the patient and to agree on an appropriate tapering schedule and follow-up plan so that patient and provider goals and expectations are clear and realistic. When opioid analgesics are being discontinued due to a suspected substance use disorder, evaluate and treat the patient, or refer for evaluation and treatment of the substance use disorder. Treatment should include evidence-based approaches, such as medication assisted treatment of opioid use disorder. Complex patients with co-morbid pain and substance use disorders may benefit from referral to a specialist. There are no standard opioid tapering schedules that are suitable for all patients. Good clinical practice dictates a patient-specific plan to taper the dose of the opioid gradually. For patients on hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets who are physically opioid-dependent, initiate the taper by a small enough increment (e.g., no greater than 10% to 25% of the total daily dose) to avoid withdrawal symptoms, and proceed with dose-lowering at an interval of every 2 to 4 weeks. Patients who have been taking opioids for briefer periods of time may tolerate a more rapid taper. It may be necessary to provide the patient with lower dosage strengths to accomplish a successful taper. Reassess the patient frequently to manage pain and withdrawal symptoms, should they emerge. Common withdrawal symptoms include restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia, and mydriasis. Other signs and symptoms also may develop, including irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhea, or increased blood pressure, respiratory rate, or heart rate. If withdrawal symptoms arise, it may be necessary to pause the taper for a period of time or raise the dose of the opioid analgesic to the previous dose, and then proceed with a slower taper. In addition, evaluate patients for any changes in mood, emergence of suicidal thoughts, or use of other substances. When managing patients taking opioid analgesics, particularly those who have been treated for an extended period of time, and/or with high doses for chronic pain, ensure that a multimodal approach to pain management, including mental health support (if needed), is in place prior to initiating an opioid analgesic taper. A multimodal approach to pain management may optimize the treatment of chronic pain, as well as assist with the successful tapering of the opioid analgesic [see Warnings and Precautions (5.14) , Drug Abuse and Dependence (9.3) ] .

Side Effects Overview

6 ADVERSE REACTIONS The following serious adverse reactions are described, or described in greater detail, in other sections: Addiction, Abuse, and Misuse [see Warnings and Precautions (5.2) ] Life-Threatening Respiratory Depression [see Warnings and Precautions (5.3) ] Interactions with Benzodiazepines or Other CNS Depressants [see Warnings and Precautions (5.4) ] Neonatal Opioid Withdrawal Syndrome [see Warnings and Precautions (5.5) ] Opioid-Induced Hyperalgesia and Allodynia [see Warnings and Precautions (5.7) ] Adrenal Insufficiency [see Warnings and Precautions (5.9) ] Severe Hypotension [see Warnings and Precautions (5.10) ] Gastrointestinal Adverse Reactions [see Warnings and Precautions (5.12) ] Seizures [see Warnings and Precautions (5.13) ] Withdrawal [see Warnings and Precautions (5.14) ] Most common adverse reactions are lightheadedness, dizziness, sedation, nausea, vomiting, sweating, flushing, dysphoria, euphoria, dry mouth, and pruritus. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Rhodes Pharmaceuticals at 1-888-827-0616 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Serious adverse reactions associated with hydromorphone hydrochloride include respiratory depression and apnea and, to a lesser degree, circulatory depression, respiratory arrest, shock, and cardiac arrest. The most common adverse effects are lightheadedness, dizziness, sedation, nausea, vomiting, sweating, flushing, dysphoria, euphoria, dry mouth, and pruritus. These effects seem to be more prominent in ambulatory patients and in those not experiencing severe pain. Less Frequently Observed Adverse Reactions Cardiac disorders: tachycardia, bradycardia, palpitations Eye disorders: vision blurred, diplopia, miosis, visual impairment Gastrointestinal disorders: constipation, ileus, diarrhea, abdominal pain General disorders and administration site conditions: weakness, feeling abnormal , chills Hepatobiliary disorders: biliary colic Metabolism and nutrition disorders: decreased appetite Musculoskeletal and connective tissue disorders: muscle rigidity Nervous system disorders: headache, tremor, paraesthesia, nystagmus, increased intracranial pressure, syncope, taste alteration , involuntary muscle contractions, presyncope Psychiatric disorders: agitation, mood altered, nervousness, anxiety , depression, hallucination, disorientation, insomnia, abnormal dreams Renal and urinary disorders : urinary retention, urinary hesitation, antidiuretic effects Respiratory, thoracic, and mediastinal disorders: bronchospasm, laryngospasm Skin and subcutaneous tissue disorders: urticaria, rash, hyperhidrosis Vascular disorders: flushing, hypotension, hypertension 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of hydromorphone. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Confusional state, convulsions, drowsiness, dyskinesia, dyspnea, erectile dysfunction, fatigue, hepatic enzymes increased, hyperalgesia, hypersensitivity reaction, lethargy, myoclonus, oropharyngeal swelling, peripheral edema, and somnolence. Serotonin syndrome: Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs. Adrenal insufficiency: Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Anaphylaxis : Anaphylaxis has been reported with ingredients contained in hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets. Androgen deficiency: Cases of androgen deficiency have occurred with use of opioids for an extended period of time [see Clinical Pharmacology (12.2) ] . Hyperalgesia and Allodynia: Cases of hyperalgesia and allodynia have been reported with opioid therapy of any duration [ see Warnings and Precautions (5.7) ]. Hypoglycemia: Cases of hypoglycemia have been reported in patients taking opioids. Most reports were in patients with at least one predisposing risk factor (e.g., diabetes).

Warnhinweise und Vorsichtsmaßnahmen

5 WARNINGS AND PRECAUTIONS Opioid-Induced Hyperalgesia and Allodynia: Opioid-Induced Hyperalgesia (OIH) occurs when an opioid analgesic paradoxically causes an increase in pain, or an increase in sensitivity to pain. If OIH is suspected, carefully consider appropriately decreasing the dose of the current opioid analgesic or opioid rotation. ( 5.7 ) Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients: Regularly evaluate patients, particularly during initiation and titration. ( 5.8 ) Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off of the opioid. ( 5.9 ) Severe Hypotension: Regularly evaluate patients during dosage initiation and titration. Avoid use of hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets in patients with circulatory shock. ( 5.10 ) Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness: Monitor patients for sedation and respiratory depression. Avoid use of hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets in patients with impaired consciousness or coma. ( 5.11 ) 5.1 Risk of Accidental Overdose and Death due to Medication Errors Dosing errors can result in accidental overdose and death. Avoid dosing errors that may result from confusion between mg and mL and confusion with other hydromorphone oral solutions of different concentrations, when prescribing, dispensing, and administering hydromorphone hydrochloride oral solution. Ensure that the dose is communicated clearly and dispensed accurately. Instruct patients and caregivers on how to measure and take or administer the correct dose of hydromorphone hydrochloride oral solution and to use extreme caution when measuring the dose. Strongly advise patients and caregivers to obtain and always use a graduated device that can measure and deliver the prescribed dose accurately, and to never use household teaspoons or tablespoons to measure a dose because these are not accurate measuring devices. 5.2 Addiction, Abuse, and Misuse Hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets contain hydromorphone, a Schedule II controlled substance. As an opioid, hydromorphone hydrochloride exposes users to the risks of addiction, abuse, and misuse [see Drug Abuse and Dependence (9) ]. Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets. Addiction can occur at recommended dosages and if the drug is misused or abused. Assess each patient's risk for opioid addiction, abuse, or misuse prior to prescribing hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets, and reassess all patients receiving hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets for the development of these behaviors and conditions. Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). The potential for these risks should not, however, prevent the proper management of pain in any given patient. Patients at increased risk may be prescribed opioids such as hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets but use in such patients necessitates intensive counseling about the risks and proper use of hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets along with frequent reevaluation for signs of addiction, abuse, and misuse. Consider prescribing naloxone for the emergency treatment of opioid overdose [see Dosage and Administration (2.2) , Warnings and Precautions (5.3) ] . Opioids are sought for nonmedical use and are subject to diversion from legitimate prescribed use. Consider these risks when prescribing or dispensing hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on careful storage of the drug during the course of treatment and the proper disposal of unused drug. Contact local state professional licensing board or state-controlled substances authority for information on how to prevent and detect abuse or diversion of this product. 5.3 Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids, even when used as recommended. Respiratory depression, if not immediately recognized and treated, may lead to respiratory arrest and death. Management of respiratory depression may include close observation, supportive measures, and use of opioid antagonists, depending on the patient's clinical status [see Overdosage (10) ] . Carbon dioxide (CO 2 ) retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids. While serious, life-threatening, or fatal respiratory depression can occur at any time during the use of hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets, the risk is greatest during the initiation of therapy or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets are essential [see Dosage and Administration (2) ] . Overestimating the hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets dosage when converting patients from another opioid product can result in a fatal overdose with the first dose. Accidental ingestion of even one dose of hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets, especially by children, can result in respiratory depression and death due to an overdose of hydromorphone. Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help right away in the event of a known or suspected overdose. Opioids can cause sleep-related breathing disorders including central sleep apnea (CSA) and sleep-related hypoxemia. Opioid use increases the risk of CSA in a dose-dependent fashion. In patients who present with CSA, consider decreasing the opioid dosage using best practices for opioid taper [see Dosage and Administration (2.7) ] . Patient Access to Naloxone for the Emergency Treatment of Opioid Overdose Discuss the availability of naloxone for the emergency treatment of opioid overdose with the patient and caregiver and assess the potential need for access to naloxone, both when initiating and renewing treatment with hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets. Inform patients and caregivers about the various ways to obtain naloxone as permitted by individual state naloxone dispensing and prescribing requirements or guidelines (e.g., by prescription, directly from a pharmacist, or as part of a community-based program). Educate patients and caregivers on how to recognize respiratory depression and emphasize the importance of calling 911 or getting emergency medical help, even if naloxone is administered. Consider prescribing naloxone, based on the patient's risk factors for overdose, such as concomitant use of CNS depressants, a history of opioid use disorder, or prior opioid overdose. The presence of risk factors for overdose should not prevent the proper management of pain in any given patient. Also consider prescribing naloxone if the patient has household members (including children) or other close contacts at risk for accidental ingestion or overdose. If naloxone is prescribed, educate patients and caregivers on how to treat with naloxone [see Dosage and Administration (2.2) , Warnings and Precautions (5.2 , 5.4) , Overdosage (10) ]. 5.4 Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants Profound sedation, respiratory depression, coma, and death may result from the concomitant use of hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets with benzodiazepines and/or other CNS depressants, including alcohol (e.g., non-benzodiazepine sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids). Because of these risks, reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioid analgesics alone. Because of similar pharmacological properties, it is reasonable to expect similar risk with the concomitant use of other CNS depressant drugs with opioid analgesics [see Drug Interactions (7) ] . If the decision is made to prescribe a benzodiazepine or other CNS depressant concomitantly with an opioid analgesic, prescribe the lowest effective dosages and minimum durations of concomitant use. In patients already receiving an opioid analgesic, prescribe a lower initial dose of the benzodiazepine or other CNS depressant than indicated in the absence of an opioid, and titrate based on clinical response. If an opioid analgesic is initiated in a patient already taking a benzodiazepine or other CNS depressant, prescribe a lower initial dose of the opioid analgesic, and titrate based on clinical response. Inform patients and caregivers of this potential interaction and educate then on the signs and symptoms of respiratory depression (including sedation). If concomitant use is warranted, consider prescribing naloxone for the emergency treatment of opioid overdose [see Dosage and Administration (2.2) , Warnings and Precautions (5.3) , Overdosage (10) ]. Advise both patients and caregivers about the risks of respiratory depression and sedation when hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets are used with benzodiazepines or other CNS depressants (including alcohol and illicit drugs). Advise patients not to drive or operate heavy machinery until the effects of concomitant use of the benzodiazepine or other CNS depressant have been determined. Screen patients for risk of substance use disorders, including opioid abuse and misuse, and warn them of the risk for overdose and death associated with the use of additional CNS depressants including alcohol and illicit drugs [see Drug Interactions (7) ]. 5.5 Neonatal Opioid Withdrawal Syndrome Use of hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets for an extended period of time during pregnancy can result in withdrawal in the neonate. Neonatal opioid withdrawal syndrome, unlike opioid withdrawal syndrome in adults, may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. Observe newborns for signs of neonatal opioid withdrawal syndrome and manage accordingly. Advise pregnant women using opioids for an extended period of time of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available [see Use in Specific Populations (8.1) ] . 5.6 Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS) To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse, and misuse, the Food and Drug Administration (FDA) has required a Risk Evaluation and Mitigation Strategy (REMS) for these products. Under the requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to healthcare providers. Healthcare providers are strongly encouraged to do all of the following: Complete a REMS-compliant education program offered by an accredited provider of continuing education (CE) or another education program that includes all the elements of the FDA Education Blueprint for Health Care Providers Involved in the Management or Support of Patients with Pain. Discuss the safe use, serious risks, and proper storage and disposal of opioid analgesics with patients and/or their caregivers every time these medicines are prescribed. The Patient Counseling Guide (PCG) can be obtained at this link: www.fda.gov/OpioidAnalgesicREMSPCG . Emphasize to patients and their caregivers the importance of reading the Medication Guide that they will receive from their pharmacist every time an opioid analgesic is dispensed to them. Consider using other tools to improve patient, household, and community safety, such as patient-prescriber agreements that reinforce patient-prescriber responsibilities. To obtain further information on the opioid analgesic REMS and for a list of accredited REMS CME/CE, call 1-800-503-0784, or log on to www.opioidanalgesicrems.com . The FDA Blueprint can be found at www.fda.gov/OpioidAnalgesicREMSBlueprint . 5.7 Opioid-Induced Hyperalgesia and Allodynia Opioid-Induced Hyperalgesia (OIH) occurs when an opioid analgesic paradoxically causes an increase in pain, or an increase in sensitivity to pain. This condition differs from tolerance, which is the need for increasing doses of opioids to maintain a defined effect [see Dependence (9.3) ]. Symptoms of OIH include (but may not be limited to) increased levels of pain upon opioid dosage increase, decreased levels of pain upon opioid dosage decrease, or pain from ordinarily non-painful stimuli (allodynia). These symptoms may suggest OIH only if there is no evidence of underlying disease progression, opioid tolerance, opioid withdrawal, or addictive behavior. Cases of OIH have been reported, both with short-term and longer-term use of opioid analgesics. Though the mechanism of OIH is not fully understood, multiple biochemical pathways have been implicated. Medical literature suggests a strong biologic plausibility between opioid analgesics and OIH and allodynia. If a patient is suspected to be experiencing OIH, carefully consider appropriately decreasing the dose of the current opioid analgesic or opioid rotation (safely switching the patient to a different opioid moiety) [see Dosage and Administration (2.7) , Warnings and Precautions (5.14) ] . 5.8 Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients The use of hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets in patients with acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment is contraindicated. Patients with Chronic Pulmonary Disease: Hydromorphone hydrochloride oral solution- or hydromorphone hydrochloride tablets-treated patients with significant chronic obstructive pulmonary disease or cor pulmonale, and those with a substantially decreased respiratory reserve, hypoxia, hypercapnia, or pre-existing respiratory depression are at increased risk of decreased respiratory drive including apnea, even at recommended dosages of hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets [see Warnings and Precautions (5.3) ]. Elderly, Cachectic, or Debilitated Patients: Life-threatening respiratory depression is more likely to occur in elderly, cachectic, or debilitated patients because they may have altered pharmacokinetics or altered clearance compared to younger, healthier patients [see Warnings and Precautions (5.3) ] . Regularly evaluate patients, particularly when initiating and titrating hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets and when hydromorphone hydrochloride is given concomitantly with other drugs that depress respiration [see Warnings and Precautions (5.3 , 5.4) , Drug Interactions (7) ] . Alternatively, consider the use of non-opioid analgesics in these patients. 5.9 Adrenal Insufficiency Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Presentation of adrenal insufficiency may include non-specific symptoms and signs including nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure. If adrenal insufficiency is suspected, confirm the diagnosis with diagnostic testing as soon as possible. If adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids. Wean the patient off of the opioid to allow adrenal function to recover and continue corticosteroid treatment until adrenal function recovers. Other opioids may be tried as some cases reported use of a different opioid without recurrence of adrenal insufficiency. The information available does not identify any particular opioids as being more likely to be associated with adrenal insufficiency. 5.10 Severe Hypotension Hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets may cause severe hypotension including orthostatic hypotension and syncope in ambulatory patients. There is increased risk in patients whose ability to maintain blood pressure has already been compromised by a reduced blood volume or concurrent administration of certain CNS depressant drugs (e.g. phenothiazines or general anesthetics) [see Drug Interactions (7) ]. Regularly evaluate these patients for signs of hypotension after initiating or titrating the dosage of hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets. In patients with circulatory shock, hydromorphone hydrochloride may cause vasodilation that can further reduce cardiac output and blood pressure. Avoid the use of hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets in patients with circulatory shock. 5.11 Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness In patients who may be susceptible to the intracranial effects of CO 2 retention (e.g., those with evidence of increased intracranial pressure or brain tumors), hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets may reduce respiratory drive, and the resultant CO 2 retention can further increase intracranial pressure. Monitor such patients for signs of sedation and respiratory depression, particularly when initiating therapy with hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets. Opioids may also obscure the clinical course in a patient with a head injury. Avoid the use of hydromorphone hydrochloride in patients with impaired consciousness or coma. 5.12 Risks of Use in Patients with Gastrointestinal Conditions Hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets are contraindicated in patients with known or suspected gastrointestinal obstruction, including paralytic ileus. The hydromorphone in hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets may cause spasm of the sphincter of Oddi. Opioids may cause increases in serum amylase. Regularly evaluate patients with biliary tract disease, including acute pancreatitis, for worsening symptoms. 5.13 Increased Risk of Seizures in Patients with Seizure Disorders The hydromorphone in hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets may increase the frequency of seizures in patients with seizure disorders, and may increase the risk of seizures occurring in other clinical settings associated with seizures. Regularly evaluate patients with a history of seizure disorders for worsened seizure control during hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets therapy. 5.14 Withdrawal Do not abruptly discontinue hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets in a patient physically dependent on opioids. When discontinuing hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets in a physically dependent patient, gradually taper the dosage. Rapid tapering of hydromorphone in a patient physically dependent on opioids may lead to a withdrawal syndrome and return of pain [see Dosage and Administration (2.7) , Drug Abuse and Dependence (9.3) ]. Additionally, avoid the use of mixed agonist/antagonist (e.g., pentazocine, nalbuphine, and butorphanol) or partial agonist (e.g., buprenorphine) analgesics in patients who are receiving a full opioid agonist analgesic, including hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets. In these patients, mixed agonist/antagonist and partial agonist analgesics may reduce the analgesic effect and/or precipitate withdrawal symptoms [see Drug Interactions (7) ] . 5.15 Risks of Driving and Operating Machinery Hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets may impair the mental or physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. Warn patients not to drive or operate dangerous machinery unless they are tolerant to the effects of hydromorphone hydrochloride oral solution or hydromorphone hydrochloride tablets and know how they will react to the medication. 5.16 Sulfites Hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets contain sodium metabisulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in nonasthmatic people. Use of hydromorphone hydrochloride oral solution and hydromorphone hydrochloride tablets is contraindicated in patients with hypersensitivity to sulfite-containing medications.

Pharmakokinetik

12.3 Pharmacokinetics Absorption The analgesic activity of hydromorphone hydrochloride is due to the parent drug, hydromorphone. Hydromorphone is rapidly absorbed from the gastrointestinal tract after oral administration and undergoes extensive first-pass metabolism. Exposure of hydromorphone (C max and AUC 0-24 ) is dose-proportional at a dose range of 2 and 8 mg. In vivo bioavailability following single-dose administration of the 8 mg tablet is approximately 24% (coefficient of variation 21%). Bioequivalence between the hydromorphone hydrochloride 8 mg tablet and an equivalent dose of hydromorphone hydrochloride oral solution has been demonstrated. After oral administration of hydromorphone hydrochloride, peak plasma hydromorphone concentrations are generally attained within ½ to 1 hour. Mean (%cv) Dosage Form C max (ng) T max (hrs) AUC (ng*hr/mL) T ½ (hrs) 8 mg Tablet 5.5 (33%) 0.74 (34%) 23.7 (28%) 2.6 (18%) 8 mg Oral Liquid 5.7 (31%) 0.73 (71%) 24.6 (29%) 2.8 (20%) Food Effects In a study conducted with a single 8 mg dose of hydromorphone (2 mg hydromorphone immediate-release tablets), food lowered C max by 25%, prolonged T max by 0.8 hour, and increased AUC by 35%. The effects may not be clinically relevant. Distribution At therapeutic plasma levels, hydromorphone is approximately 8 to 19% bound to plasma proteins. After an intravenous bolus dose, the steady state of volume distribution [mean (% cv)] is 302.9 (32%) liters. Elimination The systemic clearance is approximately 1.96 (20%) liters/minute. The terminal elimination half-life of hydromorphone after an intravenous dose is about 2.3 hours. Metabolism Hydromorphone is extensively metabolized via glucuronidation in the liver, with greater than 95% of the dose metabolized to hydromorphone-3-glucuronide along with minor amounts of 6-hydroxy reduction metabolites. Excretion Only a small amount of the hydromorphone dose is excreted unchanged in the urine. Most of the dose is excreted as hydromorphone-3-glucuronide along with minor amounts of 6-hydroxy reduction metabolites. Specific Populations Hepatic Impairment After oral administration of a single 4 mg dose (2 mg hydromorphone immediate-release tablets), mean exposure to hydromorphone (C max and AUC∞) is increased 4-fold in patients with moderate (Child-Pugh Group B) hepatic impairment compared with subjects with normal hepatic function. Due to increased exposure of hydromorphone, patients with moderate hepatic impairment should be started at a lower dose and closely monitored during dose titration. Pharmacokinetics of hydromorphone in severe hepatic impairment patients has not been studied. Further increase in C max and AUC of hydromorphone in this group is expected. As such, starting dose should be even more conservative [see Use in Specific Populations (8.6) ] . Renal Impairment After oral administration of a single 4 mg dose (2 mg hydromorphone immediate-release tablets), exposure to hydromorphone (C max and AUC 0-48 ) is increased in patients with impaired renal function by 2-fold in moderate (CLcr = 40 to 60 mL/min) and 3-fold in severe (CLcr < 30 mL/min) renal impairment compared with normal subjects (CLcr > 80 mL/min). In addition, in patients with severe renal impairment hydromorphone appeared to be more slowly eliminated with longer terminal elimination half-life (40 hr) compared to patients with normal renal function (15 hr). Patients with moderate renal impairment should be started on a lower dose. Starting doses for patients with severe renal impairment should be even lower. Patients with renal impairment should be closely monitored during dose titration [see Use in Specific Populations (8.7) ]. Age: Geriatric Population In the geriatric population, age has no effect on the pharmacokinetics of hydromorphone. Sex Sex has little effect on the pharmacokinetics of hydromorphone. Females appear to have higher C max (25%) than males with comparable AUC 0-24 values. The difference observed in C max may not be clinically relevant.
