The main purpose of Artvigil 150 is to encourage wakefulness in patients with sleep problems. In order to lessen excessive daytime drowsiness, it is primarily used to treat disorders including narcolepsy, obstructive sleep apnea, and shift work sleep disorder. It enhances mental clarity and alertness by increasing brain activity. To improve attention, concentration, and productivity, some people also use artvigil 150 off-label. It does not, however, take the place of getting enough sleep or treat sleep problems. It should be taken under a doctor's supervision because it may cause anxiety, headaches, and sleeplessness.
