6.1 Clinical Trials 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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice.

During clinical trials, 397 subjects used clindamycin phosphate and benzoyl peroxide gel once daily for 11 weeks for the treatment of moderate to moderately severe facial acne vulgaris.

All subjects were graded for facial local skin reactions (erythema, peeling, burning, and dryness) on the following scale: 0 = absent, 1 = mild, 2 = moderate, and 3 = severe.

The percentage of subjects that had symptoms present before treatment (at baseline) and during treatment is presented in Table 1.

6.2 Post-marketing Experience The following adverse reactions have been identified during post-approval use of clindamycin phosphate and benzoyl peroxide gel.

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 hospitalization, has been reported in postmarketing use with clindamycin phosphate and benzoyl peroxide gel.

Urticaria, application site reactions, including discoloration have been reported.
