Modafinil is a prescription medicine that treats excessive tiredness caused by sleep conditions such as sleep apnea, narcolepsy, and shift work sleep disorder. Modafinil is available under the brand name Provigil.
Modafinil is mainly used for treating the following medical conditions:
It is a disorder that happens when your breathing starts and stops while you sleep as the airway gets blocked.
It is a medical condition that happens when the brain’s control of your sleep-wake cycle does not work.
Shift work disorder
This condition involves trouble sleeping when you need to or extreme sleepiness when you wish to be awake.
Modafinil controls the levels of chemical messengers in your brain and exerts a stimulant effect to decrease extreme sleepiness.
It is important to take Modafinil tablets as your doctor has recommended.
You can take Modafinil tablets with or without food as prescribed by the doctor once in the morning to treat narcolepsy. Your doctor might divide the dosage into morning and noon doses.
To treat obstructive sleep apnea, take Modafinil daily with or without food in the morning. Unless the doctor recommends it, continue your other treatments, like the CPAP machine.
When treating shift work sleep disorder, take a Modafinil tablet at least one hour before your work shift starts.
Even if you feel well, continue your treatment with Modafinil unless the doctor tells you to stop.
Suddenly stopping treatment with Modafinil can increase your risk of experiencing withdrawal symptoms such as chills, shaking, confusion, vomiting, and nausea.
