Hypersensitivity to Clindamycin, lincomycin, benzoyl peroxide, or any component of the formulation; history of regional enteritis, ulcerative colitis, pseudomembranous colitis or antibiotic-associated colitis.

Clindamycin is a semi-synthetic derivative of lincomycin. It inhibits bacterial protein synthesis by reversibly binding to the 50S ribosomal subunits thus blocking the transpeptidation or translocation reactions of susceptible organisms. Benzoyl peroxide has mild keratolytic effect and antimicrobial activity which is attributed to its potent oxidizing activity. Clindamycin and Benzoyl peroxide are both active against Propionibacterium acnes, an organism associated with acne vulgaris.
