Nuvigil 150 mg contains armodafinil, a prescription medicine used to promote wakefulness in adults with excessive daytime sleepiness linked to certain sleep-related conditions. It may help people remain more alert during the day when sleepiness is associated with narcolepsy, obstructive sleep apnea, or shift work disorder. However, it does not replace adequate sleep, correct an irregular schedule, or treat every underlying cause of fatigue.
The Nuvigil 150 mg medication guide explains important information about its uses, dosing, precautions, possible side effects, and interactions. The appropriate dose and timing depend on the condition being treated, the person’s medical history, and other medicines they may be taking. Patients should use it only as prescribed and should not increase, reduce, or change the timing of a dose without speaking with a healthcare professional.
Before starting treatment, patients should tell their prescriber about heart problems, high blood pressure, liver or kidney disease, mental health conditions, allergies, pregnancy, or breastfeeding. They should also mention all prescription medicines, over-the-counter products, and supplements, because armodafinil may affect how some medicines work. Hormonal contraceptives may be less reliable while taking armodafinil and for a period after treatment, so medical advice about alternative contraception may be needed.
Possible side effects include headache, nausea, dry mouth, reduced appetite, dizziness, or difficulty sleeping. Seek urgent medical attention for a severe rash, blistering or peeling skin, swelling of the face or throat, trouble breathing, chest pain, fainting, or significant mood or behavior changes. Alcohol and other substances that affect alertness should be discussed with a healthcare professional.

If daytime sleepiness continues, worsens, or interferes with driving, work, or daily activities, a healthcare professional can help evaluate possible causes and recommend an appropriate treatment plan.
