Retin-A.

Retin-A (tretinoin topical) is a medicine intended for the treatment of acne. Your acne may get worse at first, but this is a normal occurrence in the course of the treatment – just continue applying this medicine. Make sure you use clean dry hands and apply the medicine in a thin layer to clean and dry skin. Wash your skin (the area affected) with some mild soap and pat dry with a soft towel. It's recommended to wait for some 20 minutes for the skin to dry – and then you can apply Retin-A. You are normally supposed to apply it before going to bed. If you happened to miss an application – skip it and go back to the normal schedule. However, you should know that skipping to many applications will affect your treatment and you will be unable to treat your acne as fast as you hope this is possible. Make sure you inform your health care provider if you are using any of the following medications that have been reported to interact with Retin-A and therefore need to be reported: chlorpromazine, diuretics, antibiotics, sulfa drugs, prochlorperazine, tetracycline, and promethazine. At the beginning of your treatment Retin-A may cause a number of side effects – such as redness, peeling, tingling, warmth, itching, swelling, irritation, burning, dryness, and stinging.
