Administration of Modavigil

Modavigil dosage and administration.

Modavigil can be prescribed to people who got a complete examination of their excessive sleep, which was caused by such disorders as narcolepsy, sleep apnea and shift work disorder.  The evaluation should be made with the help of DSM or ICSD criteria. This medical check-up usually includes physical examination, complete history and laboratory testing. Some people have several sleep disorders at the same time. Sometimes it happens that a person suffers from SWSD and OSAHS simultaneously. Such patients require more supervision and attention from the doctor.


If you faced with Narcolepsy it is recommended to take from 200mg to 400 mg of Generic Modavigil each day in the morning, or sometimes you can divide the dose and take it 2 times a day. It is suggested to swallow tablets whole, don’t chew them. Such high doses of 400mg were tolerated normally by the patients, but there is no concrete and evident information that this dose can lead to additional benefits in comparison with the dose of 200mg. Those patients, who need the dose more than 200 mg, shouldn’t exceed the norm of 400mg.

Obstructive Sleep Apnea.

For those who suffer from OSA, it is suggested to take from 200mg to 400 mg of the medication in the morning as a single dose. Some can divide it and take two times a day: in the morning and noon as well. Swallow the tablets whole. It is reported that high doses of 400mg were well tolerated by the patients, but there were not noticed any additional positive effects from the drug on the organism. One shouldn’t take more than 400mg per day.  Modavigil treats the excessive daytime sleep in those who have OSA. It is also recommended to use Continuous Positive Airway Pressure together with the medication in order to get a better result.

Shift Work Sleep Disorder.

For those who faced with SWSD it is suggested to take 200 mg of Modavigil. One should have it 1 hour before the shift start. It must be taken as a single dose and should be swallowed whole. With time when you understand what effects the drug has on your organism, the dose can be changed, of course, after the consultation with your doctor. Only when he approves everything you can order Modavigil online.

Special population dosing.

Those who have severe hepatic impairment the dose must be reduced to one half of that which is recommended for people who suffer from normal hepatic function. There is no concrete information about Modavigil efficacy in those who have severe renal impairment. Those who buy Modavigil for their parents should remember that the dose must be reduced there, which is explained by the age.
