Provigil is a wakefulness-promoting drug. It is believed to function by modifying the brain's natural chemicals (neurotransmitters).

Provigil is prescribed for the treatment of excessive drowsiness caused by sleep apnea, narcolepsy, or shift work sleep disorder.

In addition to the uses indicated in this drug guide, Provigil may also be used for reasons not specified here. There are several generic versions of Provigil (modafinil) available today. One may conveniently buy modafinil online.



If you have ever had an allergic reaction or rash while taking modafinil or armodafinil, you should not take Provigil (Nuvigil).


Provigil may produce skin responses severe enough to need hospitalization. Stop taking this medication and get immediate medical attention if you develop a rash or hives, blisters or peeling, mouth ulcers, difficulty breathing or swallowing, fever, limb swelling, dark urine, yellowing of the skin or eyes, or swelling of the face.


Inform your doctor if you have angina (chest discomfort), liver or renal illness, a cardiac condition, a history of drug addiction, if you are on blood pressure medicine, or if you have recently had a heart attack.


Modafinil has an influence on the central nervous system. This drug may affect your cognitive or behavioral abilities. Be cautious if you are driving or doing any activity that needs vigilance. Avoid engaging in potentially hazardous tasks until you know how this drug affects your alertness.


It is unknown if this medication may damage a fetus. Inform your physician if you are or want to become pregnant.


Provigil may reduce the effectiveness of some contraceptives. During your therapy, hormonal contraception (pills, injections, implants, skin patches, and vaginal rings) may not be effective enough to prevent conception. Discuss with your doctor the most effective forms of contraception to use while taking Provigil.


It is unknown whether modafinil enters breast milk or if it might be harmful to a breastfeeding infant. It is necessary to inform your physician though.


Provigil is not authorized for use by anybody under the age of 17.


Take Provigil as directed by your physician. Follow all instructions on the label of your medication. Do not use this medication in bigger or lower doses or for a longer duration than prescribed.


Modafinil may be addictive. Never share Provigil, particularly with someone who has a history of substance misuse or addiction. Keep the medicine in a location that is inaccessible to others. Selling or distributing this medication is illegal.

Typically, Provigil is prescribed for 12 weeks or fewer.


If you are using Provigil to treat drowsiness caused by obstructive sleep apnea, you may also be treated with a CPAP machine. This device is an air pump attached to a mask that pushes pressurized air softly into your nose as you sleep. The pump does not breathe for you, but the modest air pressure prevents blockage by keeping your airway open.


If your doctor has not instructed you to cease using your CPAP machine while sleeping, you should continue to use it. A combination of CPAP and Provigil may be required for optimal treatment of your illness.


Provigil will not cure or treat the underlying causes of obstructive sleep apnea. Follow your physician's directions for any other therapies for this illness.


Contact your physician if you continue to have extreme drowsiness after taking this medication.


Taking Provigil does not replace obtaining sufficient sleep.


Temperature-controlled storage away from moisture and heat.


Monitor the quantity of medication consumed from each fresh bottle. Modafinil is a substance of abuse, and you should be informed if somebody is misusing or abusing your medication.


Dosage details Usual dose for adults with narcolepsy:


200 mg per day taken orally in the morning


Dosage for Sleep apnea:

200 mg per day taken orally in the morning


Normal dosage for adults with shift work sleep disorder:


200 mg orally once day, one hour before the beginning of the work shift


Standard pediatric dose for attention deficit hyperactivity disorder:


Not FDA approved.

The FDA's Pediatric Advisory Committee has unanimously recommended that a particular caution against the use of modafinil in children be added to the labeling; use only if first- and second-line therapies have failed and the benefits exceed the risks.

Children weighing less than 30 kilograms: 200-340 mg daily

Children above 30 kg: 300 to 425 mg


In randomized, double-blind, placebo-controlled pediatric research, an 85 mg film-coated tablet (not commercially available) was used to provide these doses. All trials used a titration procedure, although the duration of titration differed (3 weeks vs. 7-9 days); clinical improvement was shown sooner with the shorter titration duration.

Provigil side effects

Get immediate medical attention if you exhibit symptoms of an allergic reaction to Provigil: Itching; trouble breathing; swelling of the cheeks, lips, tongue, and throat.


This list of side effects is not an exhaustive one. Consult your physician for guidance on side effects.

Other pharmaceuticals, including prescription and over-the-counter medications, vitamins, and herbal supplements, may interact with modafinil. Inform each of your healthcare providers of any medications you currently take, as well as any new or discontinued medications.
