The typical recommended dose of Modalert 200 (modafinil) for adults is 200 mg per day. For most conditions, including narcolepsy, sleep apnea, and shift work sleep disorder, this dose is usually taken once in the morning to help with daytime sleepiness. In some cases, a healthcare provider may adjust the dosage based on the individual’s needs or response to the medication, but 200 mg is the standard starting dose. It's important to follow your doctor’s instructions carefully and never exceed the recommended dose, as higher amounts can increase the risk of side effects.
