Drug Interaction Report

Using porfimer together with acitretin may increase the risk of a photosensitivity reaction (e.G., redness, swelling, itching, burning sensation, feeling hot, and/or blisters), following exposure to sunlight or bright indoor lights such as examination, dental or operating room lamps; floodlights; halogen lights; and unshaded light bulbs at close proximity. It is recommended that acitretin be avoided for at least 30 days following therapy with porfimer, and until a test for residual photosensitivity shows no photosensitivity reaction within 24 hours. In some cases, it might be necessary to avoid photosensitizing medications for 90 days or longer, although it may not be feasible to interrupt some treatments for that long, especially if they are medically necessary. Exposing your skin to normal indoor lighting is helpful as it will help your body get rid of porfimer more quickly, so you do not need to stay inside in the dark. Check with your doctor to see if you should temporarily withhold any of your medications after taking porfimer or if you have any other questions. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Take acitretin with food. Women must avoid all drinks, food, and medicines (including over-the-counter products) that contain alcohol while taking acitretin or for 2 months after stopping treatment. Alcoholic beverages increase the risk for birth defects while taking acitretin. Acitretin can cause severe, life-threatening birth defects if the mother takes the medication during pregnancy. Never use acitretin if you are pregnant. Both a primary and a secondary form of birth control must be used together and for at least 3 years after stopping therapy. Talk with your doctor about other possible birth control methods while you are taking acitretin. It is important that you tell your healthcare provider about all other medications that you are using including vitamins and herbs. Do not stop using your medications without first talking to your doctor.
