Provigil 100 mg

What is Provigil 100 mg?

Provigil 100 mg is an oral tablet containing modafinil. It promotes wakefulness and is used to treat excessive daytime sleepiness caused by narcolepsy, obstructive sleep apnea (OSA) or shift work sleep (SWS) disorder. Provigil does not treat the underlying disorder, it only makes people feel more awake. Provigil does not take the place of other treatments for narcolepsy or OSA. These should be continued while you are taking Provigil.

How does Provigil 100 mg work?

Modafinil works on the brain pathways that help to control alertness. While its full mechanism has not been established, it appears to influence chemical messengers such as dopamine, norepinephrine, histamine and orexin. These messengers help control attention, motivation and the body’s sleep wake pattern.

By supporting activity in these pathways, Provigil 100 mg may reduce the tendency to fall asleep during the day. It does not cure the underlying sleep disorder and people with obstructive sleep apnea should continue treatments such as CPAP if they have been prescribed.

Key Features

What is it used for?

Provigil 100 mg may be recommended for excessive daytime sleepiness associated with:

• Narcolepsy is a condition that can cause sudden sleep episodes and difficulty maintaining wakefulness
• Obstructive sleep apnea where sleepiness continues despite treatment for interrupted breathing during sleep
• Shift work sleep disorder especially when work schedules interfere with the body’s usual sleep routine

For sleepiness linked with obstructive sleep apnea, Provigil 100 mg does not treat airway obstruction. It is usually considered alongside ongoing therapies aimed at managing the breathing disorder.
