Are there any interactions with Provigil?

Provigil may interact with birth control pills, causing them to be less effective. If you take birth control pills, you should use a back-up form of birth control such as condoms or foam while taking Provigil and continue it for one month after stopping the drug. If you take Provigil long-term, you may consider using a different form of birth control other than birth control pills.

Provigil may affect the blood levels of certain drugs, including warfarin (brand name Coumadin), clomipramine (Anafranil), cyclosporine (Neoral), diazepam (Valium), phenytoin (Dilantin), desipramine (Norpramin), and imipramine (Tofranil). If you take Provigil in combination with these medicines, your doctor may need to adjust your dose of these drugs.

Caution should be used when taking Provigil with Monoamine Oxidase Inhibitors such as phenylzine (Nardil) and tranylcypromine (Parnate), as there have not been any interaction studies done with these drugs.
