What Is Armodafinil?
Armodafinil is a prescription wakefulness-promoting medicine that helps adults stay awake when certain sleep disorders cause excessive daytime sleepiness.
Armodafinil does not treat ordinary tiredness or replace adequate sleep. Patients should use it only for a diagnosed sleep-wake disorder and under appropriate medical supervision.
Armodafinil Dosage
The appropriate Armodafinil dosage depends on the condition being treated and the patient’s individual medical circumstances.
Typical adult dosing includes:
- Narcolepsy: 150mg to 250mg once daily in the morning.
- Obstructive sleep apnea: 150mg to 250mg once daily in the morning.
- Shift work disorder: 150mg once daily, approximately one hour before the start of the work shift.
Patients can take Armodafinil with or without food. Swallow the tablet whole with water.
If you miss a dose and taking it later could interfere with nighttime sleep, follow your prescriber’s instructions rather than taking the missed dose late in the day. Never take two doses together to make up for a missed dose.

Important Medical Information
Armodafinil is a prescription-only medicine. Use it only under the supervision of a qualified healthcare professional and according to the approved prescribing information.
This product information does not replace professional medical advice, diagnosis, or treatment. Patients should consult their doctor or pharmacist before starting or changing Armodafinil treatment.
Armodafinil 150mg helps improve wakefulness in adults with excessive daytime sleepiness associated with narcolepsy, obstructive sleep apnea, or shift work disorder. A healthcare professional should determine the appropriate dose based on the patient’s condition.
Common Armodafinil side effects include headache, nausea, dizziness, insomnia, anxiety, dry mouth, and decreased appetite. Contact your doctor if you experience severe or unusual symptoms.
The usual Armodafinil dosage depends on the condition. Doctors commonly prescribe 150mg to 250mg once daily in the morning for narcolepsy or OSA, while they commonly prescribe 150mg approximately one hour before a work shift for shift work disorder.
Armodafinil promotes wakefulness by affecting neurotransmitter activity in the brain. It helps adults with certain sleep-wake disorders maintain alertness and reduce excessive daytime sleepiness.
Both strengths contain Armodafinil, but Armodafinil 250mg contains a higher amount of the active ingredient than Armodafinil 150mg. Your doctor should choose the appropriate strength based on your condition and treatment response.
