Modalert 200 mg is one of several medications that can help you stay awake all day. Modalert, a drug that promotes alertness, is frequently used to treat excessive daytime drowsiness brought on by illnesses such shift work disorder, narcolepsy, and sleep apnea. It increases alertness and decreases weariness by boosting dopamine and other brain chemicals. A closely similar medicine called Armodafinil and stimulants like Adderall and Ritalin, which are frequently recommended for attention deficit hyperactivity disorder (ADHD), are other drugs that encourage wakefulness. Although these medications can help keep you alert, it's best to use them under a doctor's supervision to prevent any negative effects, addiction, or abuse.
