Modalert 200 can be used every day, but only with a doctor's supervision. In order to encourage alertness, it is frequently used for ailments including narcolepsy, sleep apnea, and shift work sleep disorder. Even though many people take it every day, prolonged usage should be closely watched for adverse effects including elevated heart rate, anxiety, or sleeplessness. Avoid taking more medication than is advised or self-medicating. Seeing your doctor on a regular basis guarantees that the drug will continue to be safe and effective for you. See your doctor for safer, longer-term options if you're using Modalert for general fatigue without a specified illness.
