Side Effects Overview

6 ADVERSE REACTIONS 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 the rates in the clinical trials of another drug and may not reflect the rates observed in practice. The most frequently reported ocular adverse events were conjunctivitis, decreased visual acuity, dry eye, keratitis, ocular discomfort, ocular hyperemia, ocular pain, ocular pruritus, subconjunctival hemorrhage, and tearing. These events occurred in approximately 1%-6% of patients. Nonocular adverse events reported at a rate of 1%-4% were fever, increased cough, infection, otitis media, pharyngitis, rash, and rhinitis. The most frequently reported ocular adverse events were conjunctivitis, decreased visual acuity, dry eye, keratitis, ocular discomfort, ocular hyperemia, ocular pain, ocular pruritus, subconjunctival hemorrhage, and tearing. These events occurred in approximately 1 to 6% of patients.

Warnings & Precautions

5 WARNINGS AND PRECAUTIONS • Hypersensitivity Reactions : Hypersensitivity and anaphylaxis have been reported with systemic use of MOXIFLOXACIN. ( 5.1) • Prolonged use : May result in overgrowth of non- susceptible organisms, including fungi. If superinfection occurs, discontinue use and institute alternative therapy. ( 5.2) • Avoid Contact Lens Wear : Patients should not wear contact lenses if they have signs or symptoms of bacterial conjunctivitis. ( 5.3 ) 5.1 Hypersensitivity Reactions In patients receiving systemically administered quinolones, including moxifloxacin, serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported, some following the first dose. Some reactions were accompanied by cardiovascular collapse, loss of consciousness, angioedema (including laryngeal, pharyngeal or facial edema), airway obstruction, dyspnea, urticaria, and itching. If an allergic reaction to moxifloxacin occurs, discontinue use of the drug. Serious acute hypersensitivity reactions may require immediate emergency treatment. Oxygen and airway management should be administered as clinically indicated. 5.2 Growth of Resistant Organisms with Prolonged Use As with other anti-infectives, prolonged use may result in overgrowth of non-susceptible organisms, including fungi. If superinfection occurs, discontinue use and institute alternative therapy. Whenever clinical judgment dictates, the patient should be examined with the aid of magnification, such as slit-lamp biomicroscopy, and, where appropriate, fluorescein staining. 5.3 Avoidance of Contact Lens Wear Patients should be advised not to wear contact lenses if they have signs or symptoms of bacterial conjunctivitis.

Pharmacokinetics

12.3 Pharmacokinetics Plasma concentrations of moxifloxacin were measured in healthy adult male and female subjects who received bilateral topical ocular doses of moxifloxacin ophthalmic solution 3 times a day. The mean steady-state C max (2.7 ng/mL) and AUC 0-∞ (41.9 ng•hr/mL) values were 1600 and 1100 times lower than the mean C max and AUC reported after therapeutic 400 mg doses of moxifloxacin. The plasma half-life of moxifloxacin was estimated to be 3 hours.
