Modafinil is often prescribed at a daily dose of 200 mg, which is typically taken in one morning. For the majority of individuals with narcolepsy, obstructive sleep apnea, or shift work sleep disorder, 200 mg of modafinil is the recommended and efficient dosage, and this is what
Modalert 200 mg contains. In certain instances, a smaller first dose (100 mg) could be recommended in order to gauge tolerance. Generally speaking, taking more than 200 mg daily is not required and may raise the risk of adverse effects including headaches, sleeplessness, or anxiety. Modalert 200 should always be used under a doctor's supervision and in accordance with the recommended dosage.
