Provigil is a prescription medicine used to improve wakefulness in adults who are very sleepy due to one of the following diagnosed sleep disorders: narcolepsy, obstructive sleep apnea, or shift work disorder. Provigil will not cure these sleep disorders. Provigil may help the sleepiness caused by these conditions, but it may not stop all your sleepiness. Provigil does not take the place of getting enough sleep. Provigil may cause serious side effects including a serious rash or a serious allergic reaction that may affect parts of your body such as your liver or blood cells. Do not take Provigil if you are allergic to any of its ingredients or have had a rash or allergic reaction to modafinil (Provigil). Do not drive a car or do other dangerous activities until you know how Provigil affects you. You should avoid drinking alcohol.
Learn about medication Provigil. The recommended dosage of Provigil for patients with narcolepsy is 200 mg taken orally once a day as a single dose in the morning. Doses up to 400 mg/day, given as a single dose, have been well tolerated, but there is no consistent evidence that this dose confers additional benefit beyond that of the 200 mg/day dose. The recommended dosage of Provigil for patients with SWD is 200 mg taken orally once a day as a single dose approximately 1 hour prior to the start of their work shift. Dosage Modifications in Patients with Severe Hepatic Impairment. In patients with severe hepatic impairment, the dosage of Provigil should be reduced to one-half of that recommended for patients with normal hepatic function. Consideration should be given to the use of lower doses and close monitoring in geriatric patients.
The mechanism through which Modafinil promotes wakefulness. Modafinil has wake-promoting actions similar to sympathomimetic agents including amphetamine and methylphenidate, although the pharmacologic profile is not identical to that of the sympathomimetic amines. Modafinil is not a direct-or indirect-acting dopamine receptor agonist. However, in vitro, Modafinil binds to the dopamine transporter and inhibits dopamine reuptake. This activity has been associated in vivo with increased extracellular dopamine levels in some brain regions of animals.

Most powerful and popular cognitive enhancers. Supports memory, attentiveness, mood and improved mental performance. Boost focus, motivation and energy.
Provigil reviews often state that this supplement gives them a much cleaner energy boost than caffeine and other stimulants. For this reason, it has become popular for off-label use as a concentration enhancer.
Provigil has been shown to help people stay awake and active, as well as make their mind much clearer if their memory has been previously worsened by the onset of sleep deprivation. Studies have successfully shown a correlation between the use of this drug and retaining cognitive function in a healthy state against factors like a lack of sleep. However, not all of them could connect Provigil to an improvement in psychomotor function in human test subjects.
