A drug called Artvigil 150 mg (Armodafinil), also known by the trade name Nuvigil, is used to treat severe drowsiness brought on by narcolepsy, obstructive sleep apnea, or shift work sleep problems. It is only accessible with a doctor’s prescription and works well to treat narcolepsy-related drowsiness. Patients with narcolepsy or obstructive sleep apnea should take 150 mg to 250 mg of Armodafinil tablets orally in the morning. It’s critical to practice proper sleep hygiene, which includes sleeping in a dark, quiet room, abstaining from caffeine in the hours before bed, and keeping all of your doctor and visits.
