A 150mg dose of armodafinil, such as Artvigil 150, is the standard and most commonly prescribed amount for promoting wakefulness. It is not considered a high dose, but it is the maximum recommended daily dose. Artvigil 150 is effective for treating conditions like narcolepsy, obstructive sleep apnea, and shift work sleep disorder. While generally well-tolerated, some people may experience side effects like headache, nausea, or anxiety. If you’re sensitive to stimulants, consult your doctor before starting Artvigil 150. Never increase the dose without medical advice, as higher amounts may increase the risk of side effects.
