Nuvigil Dosage

Dosage in Obstructive Sleep Apnea (OSA) and Narcolepsy

The recommended dosage of NUVIGIL for patients with OSA or narcolepsy is 150 mg to 250 mg taken orally once a day as a single dose in the morning.

In patients with OSA, doses up to 250 mg/day, given as a single dose, have been well tolerated, but there is no consistent evidence that these doses confer additional benefit beyond that of the 150 mg/day dose .

Dosage in Shift Work Disorder (SWD)

The recommended dosage of NUVIGIL for patients with SWD is 150 mg taken orally once a day as a single dose approximately 1 hour prior to the start of their work shift.

Dosage Modification in Patients with Severe Hepatic Impairment

In patients with severe hepatic impairment, the dosage of NUVIGIL should be reduced.

Use in Geriatric Patients

Consideration should be given to the use of lower doses and close monitoring in geriatric patients.
