What other drugs could interact with this medication?
There may be an interaction between adapalene and any of the following:
- aminolevulinic acid
- vitamin A
Adapalene can irritate the skin, so other products such as harsh or abrasive cleansers, strong drying agents or other products that may be irritating should be avoided in the areas of the skin where adapalene is applied. Many over-the-counter acne medications contain sulfur, resorcinol, or salicylic acid. It is best to stop using these before starting adapalene therapy. When using other topical acne medications (e.g., erythromycin topical solution, clindamycin phosphate topical solution or benzoyl peroxide), it is best to use adapalene at night and the others in the morning.
Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them. Depending on your specific circumstances, your doctor may want you to:
- stop taking one of the medications,
- change one of the medications to another,
- change how you are taking one or both of the medications, or
- leave everything as is.
An interaction between two medications does not always mean that you must stop taking one of them. In many cases, interactions are intended or are managed by close monitoring. Speak to your doctor about how any drug interactions are being managed or should be managed.
