Advisory information

contraindications
CONTRAINDICATIONS Clindamycin and Benzoyl Peroxide Gel is contraindicated in those individuals who have shown hypersensitivity to any of its components or to lincomycin. It is also contraindicated in those having a history of regional enteritis, ulcerative colitis, or antibiotic-associated colitis.
Special warnings and precautions
PRECAUTIONS General: For dermatological use only; not for ophthalmic use. Concomitant topical acne therapy should be used with caution because a possible cumulative irritancy effect may occur, especially with the use of peeling, desquamating, or abrasive agents. The use of antibiotic agents may be associated with the overgrowth of non-susceptible organisms including fungi. If this occurs, discontinue use of this medication and take appropriate measures. Avoid contact with eyes and mucous membranes. Clindamycin and erythromycin containing products should not be used in combination. In vitro studies have shown antagonism between these two antimicrobials. The clinical significance of this in vitro antagonism is not known. Information for Patients: Patients using Clindamycin and Benzoyl Peroxide Gel should receive the following information and instructions: 1. Clindamycin and Benzoyl Peroxide Gel is to be used as directed by the physician. It is for external use only. Avoid contact with eyes, and inside the nose, mouth, and all mucous membranes, as this product may be irritating. 2. This medication should not be used for any disorder other than that for which it was prescribed. 3. Patients should not use any other topical acne preparation unless otherwise directed by physician. 4. Patients should minimize or avoid exposure to natural or artificial sunlight (tanning beds or UVA/B treatment) while using clindamycin and benzoyl peroxide gel. To minimize exposure to sunlight, a wide-brimmed hat or other protective clothing should be worn, and a sunscreen with SPF 15 rating or higher should be used. 5. Patients who develop allergic symptoms such as severe swelling or shortness of breath should discontinue Clindamycin and Benzoyl Peroxide Gel and contact their physician immediately. In addition, patients should report any signs of local adverse reactions to their physician. 6. Clindamycin and Benzoyl Peroxide Gel may bleach hair or colored fabric. 7. Clindamycin and Benzoyl Peroxide Gel can be stored at room temperature up to 25°C (77°F) for 3 months. Do not freeze. Discard any unused product after 3 months. 8. Before applying Clindamycin and Benzoyl Peroxide Gel to affected areas wash the skin gently, then rinse with warm water and pat dry. Carcinogenesis, Mutagenesis, Impairment of Fertility: Benzoyl peroxide has been shown to be a tumor promoter and progression agent in a number of animal studies. The clinical significance of this is unknown. Benzoyl peroxide in acetone at doses of 5 and 10 mg administered twice per week induced skin tumors in transgenic Tg.AC mice in a study using 20 weeks of topical treatment. In a 52 week dermal photocarcinogenicity study in hairless mice, the median time to onset of skin tumor formation was decreased and the number of tumors per mouse increased following chronic concurrent topical administration of clindamycin and benzoyl peroxide gel with exposure to ultraviolet radiation (40 weeks of treatment followed by 12 weeks of observation). In a 2-year dermal carcinogenicity study in rats, treatment with clindamycin and benzoyl peroxide gel at doses of 100, 500 and 2000 mg/kg/day caused a dose-dependent increase in the incidence of keratoacanthoma at the treated skin site of male rats. The incidence of keratoacanthoma at the treated site of males treated with 2000 mg/kg/day (8 times the highest recommended adult human dose of 2.5 g clindamycin and benzoyl peroxide gel based on mg/m2) was statistically significantly higher than that in the sham- and vehicle-controls. Genotoxicity studies were not conducted with clindamycin and benzoyl peroxide gel. Clindamycin phosphate was not genotoxic in Salmonella typhimurium or in a rat micronucleus test. Clindamycin phosphate sulfoxide, an oxidative degradation product of clindamycin phosphate and benzoyl peroxide, was not clastogenic in a mouse micronucleus test. Benzoyl peroxide has been found to cause DNA strand breaks in a variety of mammalian cell types, to be mutagenic in S. typhimurium tests by some but not all investigators, and to cause sister chromatid exchanges in Chinese hamster ovary cells. Studies have not been performed with Clindamycin and Benzoyl Peroxide Gel or benzoyl peroxide to evaluate the effect on fertility. Fertility studies in rats treated orally with up to 300 mg/kg/day of clindamycin (approximately 120 times the amount of clindamycin in the highest recommended adult human dose of 2.5 g clindamycin and benzoyl peroxide gel, based on mg/m2) revealed no effects on fertility or mating ability. Pregnancy: Teratogenic Effects: Pregnancy Category C: Animal reproductive/developmental toxicity studies have not been conducted with clindamycin and benzoyl peroxide gel or benzoyl peroxide. Developmental toxicity studies performed in rats and mice using oral doses of clindamycin up to 600 mg/kg/day (240 and 120 times amount of clindamycin in the highest recommended adult human dose based on mg/m2, respectively) or subcutaneous doses of clindamycin up to 250 mg/kg/day (100 and 50 times the amount of clindamycin in the highest recommended adult human dose based on mg/m2, respectively) revealed no evidence of teratogenicity. There are no well-controlled trials in pregnant women treated with Clindamycin and Benzoyl Peroxide Gel. It also is not known whether Clindamycin and Benzoyl Peroxide Gel can cause fetal harm when administered to a pregnant woman. Nursing Women: It is not known whether Clindamycin and Benzoyl Peroxide Gel is excreted in human milk after topical application. However, orally and parenterally administered clindamycin has been reported to appear in breast milk. Because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use: Safety and effectiveness of this product in pediatric patients below the age of 12 have not been established.
Adverse reactions
ADVERSE REACTIONS During clinical trials, the most frequently reported adverse event in the clindamycin and benzoyl peroxide gel treatment group was dry skin (12%). The Table below lists local adverse events reported by at least 1% of patients in the clindamycin and benzoyl peroxide gel and vehicle groups. Local Adverse Events – all causalities in >/= 1% of patients Clindamycin and Benzoyl Peroxide n=420 Vehicle n=168 Application site reaction 13 (3%) 1 (<1%) Dry skin 50 (12%) 10 (6%) Pruritus 8 (2%) 1 (<1%) Peeling 9 (2%) - Erythema 6 (1%) 1 (<1%) Sunburn 5 (1%) - The actual incidence of dry skin might have been greater were it not for the use of a moisturizer in these studies. Anaphylaxis, as well as allergic reactions leading to hospitalization, have been reported during post-marketing use of clindamycin/benzoyl peroxide products. 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.

Usage information

Dosing and administration
DOSAGE AND ADMINISTRATION Clindamycin and Benzoyl Peroxide Gel should be applied twice daily, morning and evening, or as directed by a physician, to affected areas after the skin is gently washed, rinsed with warm water and patted dry.
Pregnancy and lactation
Nursing Women: It is not known whether Clindamycin and Benzoyl Peroxide Gel is excreted in human milk after topical application. However, orally and parenterally administered clindamycin has been reported to appear in breast milk. Because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
