Common use

Modvigil is primarily indicated for the treatment of narcolepsy, obstructive sleep apnea (with residual daytime sleepiness despite primary therapy), and shift work sleep disorder. Off-label, it is sometimes used to support cognitive function in attention deficit hyperactivity disorder (ADHD), fatigue associated with multiple sclerosis, and jet lag, though these uses require careful medical supervision. It is not approved for general fatigue or as a study aid in healthy individuals.

Dosage and direction

The standard adult dosage for Modvigil is 200 mg taken orally once daily, preferably in the morning. For shift work sleep disorder, take approximately one hour before the start of the work shift. Dosage may be adjusted based on individual response and tolerability, though doses above 400 mg per day are not recommended. Tablets should be swallowed whole with water, with or without food. Do not crush or chew.

Precautions

Patients should be monitored for the emergence of new psychiatric symptoms, including anxiety, depression, or psychosis. Use with caution in those with a history of cardiovascular disease, hypertension, or arrhythmias. Modvigil may impair the ability to operate machinery or drive; assess individual response before engaging in hazardous activities. Avoid alcohol and other CNS depressants during treatment. Periodic evaluation of hepatic function is advised during prolonged therapy.

Contraindications

Modvigil is contraindicated in patients with known hypersensitivity to modafinil or armodafinil. It should not be used in those with symptomatic cardiovascular disease, uncontrolled hypertension, or history of left ventricular hypertrophy. Concomitant use with monoamine oxidase inhibitors (MAOIs) is contraindicated due to risk of hypertensive crisis. Not recommended during pregnancy or breastfeeding unless potential benefits outweigh risks.

Possible side effects

Common side effects (≥1%) include headache, nausea, nervousness, anxiety, insomnia, dizziness, and dry mouth. Less frequently, palpitations, tachycardia, hypertension, diarrhea, or blurred vision may occur. Rare but serious adverse effects include Stevens-Johnson syndrome, angioedema, multiorgan hypersensitivity reactions, and psychiatric symptoms such as aggression or suicidal ideation. Discontinue and seek medical attention if severe reactions develop.

Drug interaction

Modvigil is a moderate inducer of CYP3A4 and may reduce the efficacy of hormonal contraceptives, cyclosporine, midazolam, and certain anticoagulants. Concurrent use with CYP2C19 inhibitors (e.g., fluoxetine, omeprazole) may increase modafinil concentrations. It may potentiate sympathomimetic agents and interact with serotonergic drugs, increasing risk of serotonin syndrome. Dose adjustments of concomitant medications may be necessary.

Missed dose

If a dose is missed, take it as soon as remembered unless it is close to the next scheduled dose. Do not double the dose to make up for a missed one. Taking Modvigil late in the day may cause insomnia.

Overdose

Symptoms of overdose may include agitation, confusion, tachycardia, hypertension, hallucinations, or gastrointestinal distress. There is no specific antidote; treatment is supportive and symptomatic. Maintain hydration and vital signs. Hemodialysis is not expected to be effective due to high protein binding. Contact a poison control center or seek emergency medical attention immediately.

Storage

Store at room temperature (15–30°C or 59–86°F) in a dry place, protected from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.
