Drug Interactions
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Avoid using other skin products that are harsh, irritating, or drying on the treated area. These products include hair perming solutions, alcohol/lime/menthol-containing products (such as astringents, toners, shaving lotion), medicated or abrasive soaps or cleansers, soaps and cosmetics with a strong drying effect (such as alpha hydroxy acids, glycolic acid), and products containing sulfur, resorcinol, or salicylic acid.
Benzoyl peroxide can be very irritating and may decrease the effectiveness of tretinoin if the two products are applied at the same time. Talk with your doctor or pharmacist about the safe use of prescription and non-prescription benzoyl peroxide products.
Negative Interactions

Tretinoin
Vitamin A
Large amounts of vitamin A can cause side effects, and oral tretinoin can cause similar side effects. Combining vitamin A with oral tretinoin is likely to increase the risk of side effects. People taking oral tretinoin should probably not take more than 10,000 IU of supplemental vitamin A per day.
