Retin-A (tretinoin) can be a part of a treatment program specially designed to treat acne. Retin-A increases the sensitivity of your skin, which means you are not supposed to spend too much time in the sun. It's recommended to wash your face with some soap and wait for 20-30 minutes for the skin to dry before applying this medicine. When applying the drug try to avoid mouth, wounds, ears, eyes and nostrils. Some people have overly sensitive skin. When using Retin-A such patients are likely to experience blisters, crusted, puffy or red skin. You may need to stop taking this medicine for your skin to become normal again or your doctor may recommend stopping the treatment.
Even though this medicine is intended for topical use it may have interactions with other drugs, such as preparations or ointments that contain sulfur or benzoyl peroxide, as well as salicylic acid and resorcinol. If you have been prescribed these other medications make sure some time passes before you apply Retin-A to avoid drug interaction. It is not exactly known whether this drug is expected to harm an unborn baby. If you have to take Retin-A and are planning to become pregnant or breastfeed discuss it with your health care provider first.
