Erythromycin-Benzoyl Peroxide Topical Gel is indicated for the topical treatment of acne vulgaris.

Erythromycin-Benzoyl Peroxide Topical Gel is contraindicated in those individuals who have shown hypersensitivity to any of its components.

Pseudomembranous colitis has been reported with nearly all antibacterial agents, including erythromycin, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents. Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia.

Studies indicate that a toxin produced by Clostridium difficile is one primary cause of “antibiotic-associated colitis.” After the diagnosis of pseudomembranous colitis has been established, therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation and treatment with an antibacterial drug clinically effective against C. difficile colitis.

Pregnancy: Teratogenic Effects Animal reproduction studies have not been conducted with Erythromycin-Benzoyl Peroxide Topical Gel or benzoyl peroxide. There was no evidence of teratogenicity or any other adverse effect on reproduction in female rats fed erythromycin base (up to 0.25% diet) prior to and during mating, during gestation and through weaning of two successive litters. There are no well-controlled trials in pregnant women with Erythromycin-Benzoyl Peroxide Topical Gel.

It also is not known whether Erythromycin-Benzoyl Peroxide Topical Gel can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Erythromycin-Benzoyl Peroxide Topical Gel should be given to a pregnant woman only if clearly needed.

In controlled clinical trials, the incidence of adverse reactions associated with the use of Erythromycin-Benzoyl Peroxide Topical Gel was approximately 3%. These were dryness and urticarial reaction. The following additional local adverse reactions have been reported occasionally: irritation of the skin including peeling, itching, burning sensation, erythema, inflammation of the face, eyes and nose, and irritation of the eyes.
