Modafinil is an oral, stimulant-like medication that promotes wakefulness. It is used to treat narcolepsy, obstructive sleep apnea, and shift work sleep disorder. In a clinical trial, modafinil significantly improved ESS in untreated sleepy patients with mild to moderate OSA. Compared with the placebo, ESS improved by 3-4 points.


Narcolepsy is a sleep disorder that causes excessive daytime drowsiness, which can disrupt an individual’s ability to function. These episodes may last from a few seconds to several minutes and are sometimes called “sleep attacks.” People with narcolepsy have low levels of the hormone hypocretin, which helps the brain stay awake.

Treatment for narcolepsy includes medication and behavioral strategies to help people avoid or cope with these episodes of sleepiness. Modvigil 200 Buy Online, which is used to treat narcolepsy and other sleep disorders, works by stimulating the brain. This drug has fewer side effects than traditional stimulant drugs and can improve alertness throughout the day.

Taking short naps throughout the day can also help manage symptoms of narcolepsy. Make sure to follow your doctor’s treatment plan for the best results.

The most common symptom of narcolepsy is daytime sleepiness (EDS). All people with narcolepsy experience this symptom, but it is more intense in some patients. In addition, other symptoms may occur. These include cataplexy, hypnagogic hallucinations, and sleep paralysis.

Obstructive sleep apnea

Obstructive sleep apnea is the most common type of sleep-disordered breathing. The disorder occurs when your throat becomes partially or completely blocked for a short time while you’re asleep, disrupting your breathing.

People who have obstructive sleep apnea snore loudly, gasp deeply and wake up feeling tired. They also may be at higher risk for heart attack and stroke, high blood pressure (hypertension), diabetes, depression, and other chronic health problems.

Your medical provider can diagnose obstructive sleep apnea by collecting your medical history, performing a physical exam, and referring you for a diagnostic sleep study. The results of the test will help your doctor make a diagnosis and develop a treatment plan.

Obstructive sleep apnea can be treated with breathing devices, oral appliances, surgery, or medication such as modafinil. The drug can help restore healthy nighttime breathing and reduce excessive daytime drowsiness.

Shift work sleep disorder

Those who work shifts, such as pilots, firefighters, nurses, security guards, and factory workers, are at risk for shift work sleep disorder. This condition can cause problems with sleeping and daytime drowsiness, as well as missed days of work and accidents on the job.

Symptoms of this condition include a decrease in overall sleep time by one to four hours nightly, which causes excessive daytime drowsiness. This is especially true in individuals who work multiple night shifts in a row or rotate between shifts.

Treatment for this condition involves changing your schedule and practicing good sleep hygiene. Your doctor may also prescribe medications, such as modafinil (Provigil), to help you stay alert during your shifts.

Other conditions

Modafinil is a central nervous system (CNS) stimulant that can be used to treat excessive daytime drowsiness. It is FDA-approved to treat narcolepsy, sleep work shift disorder, and obstructive sleep apnea (adjunct to continuous positive airway pressure or CPAP).

In a 12-week study of patients with mild to moderate obstructive sleep apnea and severe daytime sleepiness, modafinil improved sleep latency compared with a placebo. In addition, simulated driving ability improved more in patients who took modafinil than in those who took a placebo.

However, despite the benefits, these patients continue to experience sleepiness and poor daytime performance. This suggests that modafinil does not improve the alignment of the patient’s internal circadian rhythms with their work-sleep schedule.
