Artvigil 150 mg tablets are primarily used to treat sleep disorders, particularly narcolepsy and obstructive sleep apnea, by promoting wakefulness. The active ingredient, armodafinil, is a wakefulness-promoting agent that works by altering neurotransmitters in the brain, enhancing alertness, and reducing excessive daytime sleepiness. While effective, it is important to use Artvigil under medical supervision due to potential side effects, including headache, nausea, and anxiety. Patients should adhere to prescribed dosages and consult healthcare providers for any concerns regarding interactions with other medications or underlying health conditions.
