Modasmart 400 mg contains modafinil, a wakefulness-promoting medicine used to improve wakefulness in adults with excessive daytime sleepiness associated with certain sleep disorders. It is used in the management of sleepiness associated with narcolepsy, obstructive sleep apnea (OSA), and shift work disorder (SWD).
What Is Modasmart 400 mg Used For?
Modafinil is indicated to improve wakefulness in adults with excessive sleepiness associated with:
- Narcolepsy: A neurological sleep disorder that can cause excessive daytime sleepiness and an increased tendency to fall asleep.
- Obstructive Sleep Apnea: A sleep-related breathing condition that can be associated with persistent daytime sleepiness.
- Shift Work Disorder: A condition in which work schedules interfere with normal sleep and wake patterns.
Treatment should be based on an appropriate diagnosis and guidance from a qualified healthcare professional.
How Does Modasmart 400 mg Work?
It acts on the central nervous system and produces wakefulness-promoting effects that can help reduce excessive sleepiness.
The medicine is intended to support wakefulness in people with certain sleep disorders. It should not be used simply to compensate for inadequate sleep or normal tiredness.
Modasmart 400 mg Dosage Information
The appropriate dose of modafinil depends on the condition being treated and individual factors such as medical history, liver function, age, and other medicines being used.
For adults with narcolepsy or obstructive sleep apnea, the recommended dose is generally 200mg once daily in the morning. For shift work disorder, the recommended dose is generally 200mg once daily, approximately one hour before the start of the work shift.
Doses up to 400mg per day have been studied and tolerated in some patients, but current prescribing information notes that there is no consistent evidence that 400mg provides additional benefit compared with 200mg per day.
Because this product is listed as a 400mg strength, it should not be assumed that 400mg is appropriate for every person or condition. Follow the specific instructions provided by your healthcare professional and do not adjust the dose yourself.

When appropriately prescribed, modasmart 300mg may help:
- Promote wakefulness during normal waking hours

Precautions and Warnings
