Generic Name: Modafinil

  • What is Provigil?

    Provigil is used to improve awakeness in adults who are very sleepy due to shift work sleep disorder (SWSD), obstructive sleep apnea/hypopnea syndrome (OSAHS, stopping breathing temporarily during sleep), or narcolepsy (a sleep disorder characterized by excessive daytime sleepiness).

  • What is the most important information I should know about Provigil?

    Provigil is a controlled substance because it can be abused or lead to dependence. Keep Provigil in a safe place to prevent misuse and abuse.

    Provigil may cause a serious rash or serious allergic reaction. Stop Provigil and call your doctor right away or get emergency treatment if you have any of the following: skin rash or skin that blisters and peels; hives; sores in your mouth; swelling of your face, eyes, lips, tongue, or throat; trouble swallowing or breathing; or hoarse voice.

    Provigil may cause serious side effects, including heart problems such as chest pain and mental problems such as depression, anxiety, hallucinations, mania, thoughts of suicide and aggression. If you notice any of these problems, stop taking Provigil and call your doctor or get emergency help.

    This drug will not cure any sleep disorder, but it may help improve wakefulness. Provigil does not take the place of getting enough sleep. Follow your doctor's advice about good sleep habits and using other treatments.

    Provigil is used along with other medical treatments for SWSD, OSAHS, or narcolepsy and is not a replacement for a continuous positive airway pressure (CPAP) machine (a machine that helps your breathing during sleep) in people with OSAHS. It is important that you continue to use your CPAP machine while sleeping.

  • Who should not take Provigil?

    Do not take Provigil if you are allergic to any of its ingredients or if you have had a rash or allergic reaction to armodafinil, the active ingredient in Nuvigil.

  • What should I tell my doctor before I take the first dose of Provigil?

    Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Provigil. Also, talk to your doctor about your complete medical history, especially if you have ever had a heart attack, mental health problems (such as psychosis), high blood pressure, heart problems, liver or kidney problems, or a history of drug or alcohol addiction. You should also tell your doctor if you are pregnant, planning to become pregnant, or are breastfeeding.

    Tell your doctor if you use a hormonal birth control method (including birth control pills, shots, implants, patches, vaginal rings, and IUDs); Provigil can interfere with these types of birth control. Women using hormonal birth control with Provigil may have a higher chance of getting pregnant while taking Provigil and for 1 month after stopping the drug.
