What is the maximum amount of modafinil per day?

For the treatment of disorders such as shift work sleep disorder, narcolepsy, or obstructive sleep apnea, 200 mg of modafinil (Modalert 200) should be given daily, generally in the morning. Depending on the condition and the doctor's advice, the dose may be raised to 400 mg per day for certain people, but in most situations, 200 mg is the limit. Higher dosages may raise the chance of side effects including headaches, sleeplessness, or anxiety, so it's crucial to heed your doctor's advice. A doctor should always be consulted before changing your medicine because taking more than the recommended amount might pose major health hazards.
