To promote daytime alertness, clinicians frequently suggest a once-daily morning routine; however, the precise timing, dosage, and duration must be customized to your medical history and other drugs. Take the pill whole with water, don’t double doses if you miss one, and don’t alter the schedule without a doctor’s permission. Report any odd symptoms as soon as possible because modafinil can influence mood, sleep, and other medications. Modvigil 200 should never be used without expert supervision.
