Benzamycin gel is used for:
Treating severe acne. It may be used with other acne medications.
Benzamycin gel is a combination macrolide antibiotic and keratolytic (drying) agent with antibacterial actions. The effectiveness of benzoyl peroxide appears to be due to its antibacterial, peeling (keratolytic), and drying actions. How topical erythromycin treats acne is not fully known. It is thought that the improvement in acne is due to the ability of topically applied erythromycin to slow the growth on the skin of bacteria that cause the acne.
