Artvigil 150 mg tablets are a prescription medication primarily used to treat excessive daytime sleepiness associated with conditions such as narcolepsy and obstructive sleep apnea. The active ingredient, armodafinil, is a wakefulness-promoting agent that alters neurotransmitters in the brain to enhance alertness and cognitive function. Patients typically take the medication once daily, with or without food, and it is important to follow the prescribing physician’s instructions to minimize potential side effects, which may include headache, nausea, and anxiety. Regular monitoring and consultation with a healthcare provider are recommended to assess the effectiveness of the treatment and make any necessary adjustments.
