If you experience very dry and peeling skin or skin irritation, talk to your doctor or health care professional.

Talk to your pediatrician regarding the use of this medicine in children. Special care may be needed.

What should I watch for while using this medicine?

Your acne may get worse during the first few weeks of treatment, and then start to get better. It may take 8 to 12 weeks before you see the full effect. If you do not see any improvement within 4 to 6 weeks, call your doctor or health care professional.

Once you see a decrease in your acne, you may need to continue to use this medicine to control it.

Do not use products that may dry the skin like medicated cosmetics, products that contain alcohol, or abrasive soaps or cleaners. Do not use other acne or skin treatment on the same area that you use this medicine unless your doctor or health care professional tells you to.
