BenzaClin Gel contains a combination of benzoyl peroxide and clindamycin. Benzoyl peroxide has an antibacterial effect. It also has a mild drying effect that allows excess oil and dirt to be washed away. Clindamycin is an antibiotic that prevents bacteria from growing on the skin.

BenzaClin is used to treat acne.

BenzaClin may also be used for purposes not listed in this medication guide.

Use BenzaClin Gel exactly as your doctor has prescribed it for you. Using more medicine or applying it more often than prescribed will not make it work any faster, and may increase side effects. Do not use BenzaClin for longer than your doctor has prescribed.

Avoid getting BenzaClin in your eyes, mouth, or nose (or in the creases of your nose), or on your lips. If it does get into any of these areas, wash with water. Do not apply this medicine to sunburned, windburned, dry, chapped, irritated, or broken skin.
