( 4.1 ) Patients with a history of regional enteritis, ulcerative colitis, or antibiotic-associated colitis. ( 4.2 )
4.1Hypersensitivity Clindamycin phosphate and benzoyl peroxide gel is contraindicated in those individuals who have shown hypersensitivity to clindamycin, benzoyl peroxide, any components of the formulation, or lincomycin. Anaphylaxis, as well as allergic reactions leading to hospitalization, has been reported in postmarketing use with clindamycin phosphate and benzoyl peroxide gel [see Postmarketing Experience (6.2) ].
4.2Colitis/Enteritis Clindamycin phosphate and benzoyl peroxide gel is contraindicated in patients with a history of regional enteritis, ulcerative colitis, or antibiotic-associated colitis [see Warnings and Precautions (5.1) ].
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Colitis: Orally and parenterally administered clindamycin has been associated with severe colitis, which may result in death. Diarrhea, bloody diarrhea, and colitis (including pseudomembranous colitis) have been reported with the use of topical and systemic clindamycin. Clindamycin phosphate and benzoyl peroxide gel should be discontinued if significant diarrhea occurs.
( 5.1 ) Ultraviolet Light and Environmental Exposure: Minimize sun exposure following drug application. ( 5.2 )
5.1Colitis Systemic absorption of clindamycin has been demonstrated following topical use of clindamycin. Diarrhea, bloody diarrhea, and colitis (including pseudomembranous colitis) have been reported with the use of topical and systemic clindamycin. When significant diarrhea occurs, clindamycin phosphate and benzoyl peroxide gel should be discontinued.
Severe colitis has occurred following oral and parenteral administration of clindamycin with an onset of up to several weeks following cessation of therapy. Antiperistaltic agents such as opiates and diphenoxylate with atropine may prolong and/or worsen severe colitis. Severe colitis may result in death.
Studies indicate toxin(s) produced by Clostridia is one primary cause of antibiotic-associated colitis. The colitis is usually characterized by severe persistent diarrhea and severe abdominal cramps and may be associated with the passage of blood and mucus. Stool cultures for Clostridium difficile and stool assay for C. difficile toxin may be helpful diagnostically.
5.2Ultraviolet Light and Environmental Exposure Minimize sun exposure including use of tanning beds or sun lamps following drug application.
5.3Concomitant Topical Medications Concomitant topical acne therapy should be used with caution since a possible cumulative irritancy effect may occur, especially with the use of peeling, desquamating, or abrasive agents. If irritancy or dermatitis occurs, reduce frequency of application or temporarily interrupt treatment and resume once the irritation subsides. Treatment should be discontinued if the irritation persists.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following selected adverse reactions occurred in less than 0.2% of patients: application site pain (0.1%); application site exfoliation (0.1%); and application site irritation (0.1%). ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Taro Pharmaceuticals U.S.A., Inc., at 1-866-923-4914 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reactions observed in the clinical trials of a drug cannot always be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The following selected adverse reactions occurred in less than 0.2% of patients treated with clindamycin phosphate and benzoyl peroxide gel: application site pain (0.1%); application site exfoliation (0.1%); and application site irritation (0.1%).
During clinical trials, subjects were assessed for local cutaneous signs and symptoms of erythema, scaling, itching, burning and stinging. Most local skin reactions increased and peaked around Week 4 and continually decreased over time reaching near baseline levels by Week 12. The percentage of subjects that had symptoms present before treatment, the maximum value recorded during treatment, and the percent with symptoms present at Week 12 are shown in Table 1.
Table 1: Percent of Subjects with Local Skin Reactions. Combined Results from the Two Phase 3 Trials (N = 773) Before Treatment (Baseline) Maximum During Treatment End of Treatment (Week 12) Mild Mod. Mod. = Moderate Severe Mild Mod.
Severe Mild Mod. Severe Erythema 22 4 0 25 5 <1 15 2 0 Scaling 8 <1 0 18 3 0 8 1 0 Itching 10 2 0 15 2 0 6 <1 0 Burning 3 <1 0 8 2 0 2 <1 0 Stinging 2 <1 0 6 1 0 1 <1 0
6.2Postmarketing Experience 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. Anaphylaxis, as well as allergic reactions leading to hospitalizations, has been reported in postmarketing use of products containing clindamycin/benzoyl peroxide.
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Avoid using clindamycin phosphate and benzoyl peroxide gel in combination with topical or oral erythromycin-containing products because of its clindamycin component. ( 7.1 )
7.1Erythromycin Clindamycin phosphate and benzoyl peroxide gel should not be used in combination with topical or oral erythromycin-containing products due to its clindamycin component. In vitro studies have shown antagonism between erythromycin and clindamycin. The clinical significance of this in vitro antagonism is not known.
7.2Neuromuscular Blocking Agents Clindamycin has been shown to have neuromuscular blocking properties that may enhance the action of other neuromuscular blocking agents. Therefore, clindamycin phosphate and benzoyl peroxide gel should be used with caution in patients receiving such agents.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary There are no available data on clindamycin phosphate and benzoyl peroxide gel use in pregnant women to evaluate a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. The limited published data on use of clindamycin in pregnant women with exposure during the first trimester are insufficient to inform a drug-associated risk of pregnancy-related adverse outcomes (see Data ) . In limited published clinical trials with pregnant women, the systemic administration of clindamycin during the second and third trimesters has not been associated with an increased frequency of major birth defects.
In animal reproduction studies, clindamycin did not cause malformations or embryo-fetal development toxicity in pregnant rats and mice when administered during the period of organogenesis at systemic doses up to 240 times the maximum recommended human dose (MRHD) of 2.5 g clindamycin phosphate and benzoyl peroxide gel, based on body surface area (BSA) comparisons (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of major birth defects, loss, and other adverse outcomes.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Human Data In limited published trials in pregnant women administered clindamycin during the first trimester of pregnancy, there was no difference in the rate of major birth defects reported among in utero exposed infants compared to unexposed infants. These data cannot definitely establish or exclude any clindamycin-associated risk during pregnancy.
Animal Data Animal reproductive/developmental toxicity studies have not been conducted with clindamycin phosphate and benzoyl peroxide gel or benzoyl peroxide. Developmental toxicity studies of clindamycin performed in pregnant rats and mice administered during the period of organogenesis at oral doses of up to 600 mg/kg/day (240 and 120 times the MRHD for, respectively, based on BSA comparisons) or subcutaneous doses of up to 200 mg/kg/day (80 and 40 times the MRHD for clindamycin, respectively, based on BSA comparisons) revealed no malformations or embryo-fetal development toxicity.
8.2Lactation Risk Summary There are no data on the presence of clindamycin or benzoyl peroxide in human milk, the effects on the breastfed child, or the effects on milk production following topical administration. However, clindamycin has been reported to be present in breast milk in small amounts following oral and parenteral administration. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for clindamycin phosphate and benzoyl peroxide gel and any potential adverse effects on the breastfed child from clindamycin phosphate and benzoyl peroxide gel or from the underlying maternal condition.
Clinical Considerations If used during lactation and clindamycin phosphate and benzoyl peroxide gel is applied to the chest, care should be taken to avoid accidental ingestion by the infant.
8.4Pediatric Use Safety and effectiveness of clindamycin phosphate and benzoyl peroxide gel in pediatric patients under the age of 12 have not been evaluated.
8.5Geriatric Use Clinical trials of clindamycin phosphate and benzoyl peroxide gel did not include sufficient numbers of subjects aged 65 and older to determine whether they respond differently from younger subjects.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanisms of Action Clindamycin: Clindamycin is a lincosamide antibacterial [see Microbiology (12.4) ] . Benzoyl Peroxide: Benzoyl peroxide is an oxidizing agent with bactericidal and keratolytic effects but the precise mechanism of action is unknown.
12.3Pharmacokinetics The systemic absorption of clindamycin was investigated in an open-label, multiple-dose trial in 16 adult subjects with moderate to severe acne vulgaris treated with 1 gram of clindamycin phosphate and benzoyl peroxide gel applied to the face once daily for 30 days. Twelve subjects (75%) had at least one quantifiable clindamycin plasma concentration above the lower limit of quantification (LOQ = 0.5 ng/mL) on Day 1 or Day 30. On Day 1, the mean (± standard deviation) peak plasma concentration (C max ) was 0.78 ± 0.22 ng/mL (n=9 with measurable concentrations), and the mean AUC 0-t was 5.29 ± 0.81 h∙ng/mL (n=4).
On Day 30, the mean C max was 1.22 ± 0.88 ng/mL (n=10), and the mean AUC 0-t was 8.42 ± 6.01 h∙ng/mL (n=6). Clindamycin plasma concentrations were below LOQ in all subjects at 24 hours post-dose on the three tested days (Day 1, 15, and 30). Benzoyl peroxide has been shown to be absorbed by the skin where it is converted to benzoic acid.
12.4Microbiology Clindamycin binds to the 50S ribosomal subunits of susceptible bacteria and prevents elongation of peptide chains by interfering with peptidyl transfer, thereby suppressing bacterial protein synthesis. Clindamycin and benzoyl peroxide individually have been shown to have in vitro activity against Propionibacterium acnes , an organism which has been associated with acne vulgaris; however, the clinical significance of this activity against P. acnes is not known. P. acnes resistance to clindamycin has been documented.
Resistance to clindamycin is often associated with resistance to erythromycin.

🔬 Clinical Studies ▾
14 CLINICAL STUDIES The safety and efficacy of once daily use of clindamycin phosphate and benzoyl peroxide gel were assessed in two 12-week multi-center, randomized, blinded trials in subjects 12 years and older with moderate to severe acne vulgaris. The two trials were identical in design and compared clindamycin phosphate and benzoyl peroxide gel to clindamycin in the vehicle gel, benzoyl peroxide in the vehicle gel, and the vehicle gel alone. The co-primary efficacy variables were: (1) Mean absolute change from baseline at Week 12 in: Inflammatory lesion counts Non-inflammatory lesion counts (2) Percent of subjects who had a 2-grade improvement from baseline on an Evaluator's Global Severity (EGS) score.
The EGS scoring scale used in all of the clinical trials for clindamycin phosphate and benzoyl peroxide gel is as follows: Grade Description Clear Normal, clear skin with no evidence of acne vulgaris Almost Clear Rare non-inflammatory lesions present, with rare non-inflamed papules (papules must be resolving and may be hyperpigmented, though not pink-red) Mild Some non-inflammatory lesions are present, with few inflammatory lesions (papules/pustules only; no nodulocystic lesions) Moderate Non-inflammatory lesions predominate, with multiple inflammatory lesions evident: several to many comedones and papules/pustules, and there may or may not be one small nodulocystic lesion Severe Inflammatory lesions are more apparent, many comedones and papules/pustules, there may or may not be a few nodulocystic lesions Very Severe Highly inflammatory lesions predominate, variable number of comedones, many papules/pustules and many nodulocystic lesions The results of Trial 1 at Week 12 are presented in Table 2: Table 2: Trial 1 Results Trial 1 Clindamycin Phosphate and Benzoyl Peroxide Gel N = 399 Clindamycin Gel N = 408 Benzoyl Peroxide Gel N = 406 Vehicle Gel N = 201 EGSS Clear or Almost Clear 115 (29%) 84 (21%) 76 (19%) 29 (14%) 2-grade reduction from baseline 131 (33%) 100 (25%) 96 (24%) 38 (19%) Inflammatory Lesions: Mean absolute change 14.8 12.2 13 9 Mean percent (%) reduction 55% 47.1% 49.3% 34.5% Non-Inflammatory Lesions: Mean absolute change 22.1 17.9 20.6

🧪 Nonclinical Toxicology ▾
13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity, mutagenicity and impairment of fertility testing of clindamycin phosphate and benzoyl peroxide gel have not been performed. Benzoyl peroxide has been shown to be a tumor promoter and progression agent in a number of animal studies. Benzoyl peroxide in acetone at doses of 5 and 10 mg administered topically twice per week for 20 weeks induced skin tumors in transgenic Tg.AC mice.
The clinical significance of this is unknown. Carcinogenicity studies have been conducted with a gel formulation containing 1% clindamycin and 5% benzoyl peroxide. In a 2-year dermal carcinogenicity study in mice, treatment with the gel formulation at doses of 900, 2700, and 15000 mg/kg/day (1.8, 5.4, and 30 times the MRHD for clindamycin and 3.6, 10.8, and 60 times the MRHD for benzoyl peroxide, respectively, based on BSA comparisons) did not cause any increase in tumors.
However, topical treatment with a different gel formulation containing 1% clindamycin and 5% benzoyl peroxide 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 in a 2-year dermal carcinogenicity study in rats. In an oral (gavage) carcinogenicity study in rats, treatment with the gel formulation at doses of 300, 900, and 3000 mg/kg/day (1.2, 3.6, and 12 times the MRHD for clindamycin and 2.4, 7.2, and 24 times the MRHD for benzoyl peroxide, respectively, based on BSA comparisons) for up to 97 weeks did not cause any increase in tumors.
Clindamycin phosphate was not genotoxic in the human lymphocyte chromosome aberration assay. 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. Fertility studies have not been performed with clindamycin phosphate and benzoyl peroxide gel or benzoyl peroxide, but fertility and mating ability have been studied with clindamycin.
Fertility studies in rats treated orally with up to 300 mg/kg/day of clindamycin (approximately 120 times the MRHD for clindamycin, based on BSA comparisons) revealed no effects on fertility or mating ability.
