Clindamycin In 5 Percent Dextrose

INDICATIONS AND USAGE Clindamycin in 5% Dextrose Injection is indicated in the treatment of serious infections caused by susceptible anaerobic bacteria. Clindamycin in 5% Dextrose Injection is also indicated in the treatment of serious infections due to susceptible strains of streptococci, pneumococci, and staphylococci. Its use should be reserved for penicillin-allergic patients or other patients for whom, in the judgment of the physician, a penicillin is inappropriate. Because of the risk of antibiotic-associated pseudomembranous colitis, as described in the BOXED WARNING , before selecting clindamycin the physician should consider the nature of the infection and the suitability of less toxic alternatives (e.g., erythromycin). Bacteriologic studies should be performed to determine the causative organisms and their susceptibility to clindamycin. Indicated surgical procedures should be performed in conjunction with antibiotic therapy. Clindamycin in 5% Dextrose Injection is indicated in the treatment of serious infections caused by susceptible strains of the designated organisms in the conditions listed below: Lower respiratory tract infections including pneumonia, empyema, and lung abscess caused by anaerobes, Streptococcus pneumoniae , other streptococci (except E. faecalis ), and Staphylococcus aureus . Skin and skin structure infections caused by Streptococcus pyogenes, Staphylococcus aureus , and anaerobes. Gynecological infections including endometritis, nongonococcal tubo-ovarian abscess, pelvic cellulitis, and postsurgical vaginal cuff infection caused by susceptible anaerobes. Intra-abdominal infections including peritonitis and intra-abdominal abscess caused by susceptible anaerobic organisms. Septicemia caused by Staphylococcus aureus , streptococci (except Enterococcus faecalis ), and susceptible anaerobes. Bone and joint infections including acute hematogenous osteomyelitis caused by Staphylococcus aureus and as adjunctive therapy in the surgical treatment of chronic bone and joint infections due to susceptible organisms. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Clindamycin in 5% Dextrose Injection and other antibacterial drugs, Clindamycin in 5% Dextrose Injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

DOSAGE AND ADMINISTRATION If diarrhea occurs during therapy, this antibiotic should be discontinued (see WARNING box). Adults Parenteral (IV Administration) Serious infections due to aerobic gram-positive cocci and the more susceptible anaerobes (NOT generally including Bacteroides fragilis, Peptococcus species and Clostridium species other than Clostridium perfringens ): 600 to 1,200 mg/day in 2, 3 or 4 equal doses. More severe infections, particularly those due to proven or suspected Bacteroides fragilis, Peptococcus species, or Clostridium species other than Clostridium perfringens : 1,200 to 2,700 mg/day in 2, 3 or 4 equal doses. For more serious infections, these doses may have to be increased. In life-threatening situations due to either aerobes or anaerobes these doses may be increased. Doses of as much as 4,800 mg daily have been given intravenously to adults. See IV Infusion Rates section below. Alternatively, drug may be administered in the form of a single rapid infusion of the first dose followed by continuous IV infusion as follows: Table 2. Serum Clindamycin Levels Maintained, Rapid Infusion Rate and Maintenance Infusion Rate To Maintain Serum Clindamycin Levels Rapid Infusion Rate Maintenance Infusion Rate Above 4 mcg/mL 10 mg/min for 30 min 0.75 mg/min Above 5 mcg/mL 15 mg/min for 30 min 1 mg/min Above 6 mcg/mL 20 mg/min for 30 min 1.25 mg/min Pediatric patients 1 month of age to 16 years Parenteral (IV) Administration 20 to 40 mg/kg/day in 3 or 4 equal doses. The higher doses would be used for more severe infections. Clindamycin should be dosed based on total body weight regardless of obesity. As an alternative to dosing on a body weight basis, pediatric patients may be dosed on the basis of square meters body surface: 350 mg/m 2 /day for serious infections and 450 mg/m 2 /day for more severe infections. Parenteral therapy may be changed to oral clindamycin palmitate hydrochloride flavored granules or clindamycin hydrochloride capsules when the condition warrants and at the discretion of the physician. In cases of β-hemolytic streptococcal infections, treatment should be continued for at least 10 days. Pediatric Patients less than 1 month The recommended dosage is 15 to 20 mg/kg/day in 3 to 4 equal doses. See Table 3 regarding the dosing regimen for pediatric patients with post-menstrual age (PMA) less than or equal to 32 weeks, or greater than 32 weeks to less than or equal to 40 weeks. Table 3. Dosing Regimens for Pediatric Patients with PMA less than or equal to 32 weeks, or greater than 32 weeks to less than or equal to 40 weeks PMA (weeks) Dose (mg/kg) Dosing Interval (hours) Less than or equal to 32 5 8 Greater than or equal to 32 to less than or equal to 40 7 8 PMA: Post-Menstrual age IV Infusion Rates Infusion rates for Clindamycin in 5% Dextrose Injection should not exceed 30 mg per minute. The usual infusion rates are as follows: Dose Strength Time 300 mg/50 mL 6 mg/mL 10 min 600 mg/50 mL 12 mg/mL 20 min 900 mg/50 mL 18 mg/mL 30 min Administration of more than 1,200 mg in a single 1-hour infusion is not recommended. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Compatibility No incompatibility has been demonstrated with the antibiotics cephalothin, kanamycin, gentamicin, penicillin or carbenicillin. DIRECTIONS FOR USE Clindamycin in 5% Dextrose Injection in Cryovac Plastic Container Premixed Clindamycin in 5% Dextrose Injection is for intravenous administration using sterile equipment. Check for minute leaks prior to use by squeezing bag firmly. If leaks are found, discard solution as sterility may be impaired. Do not add supplementary medication. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Do not use unless solution is clear and seal is intact. Caution Do not use plastic containers in series connections. Such use could result in air embolism due to residual air being drawn from the primary container before administration of the fluid from the secondary container is complete. Preparation for Administration 1. Suspend container from eyelet support. 2. Remove protector from outlet port at bottom of container. 3. Attach administration set. Refer to complete directions accompanying set.
