Those with narcolepsy and obstructive sleep apnea take modalert 200 to stay awake. It is occasionally used off-label for ADHD and depression-related tiredness. People with these difficulties may enhance productivity and cognitive function with modafinil by improving attention and lowering daytime drowsiness. Although some users report greater alertness and motivation, it is not an authorized therapy for mental health illnesses and does not address underlying psychological concerns. Side effects may include anxiety, headaches, and sleeplessness. To guarantee safe and effective usage of Modalert for mental health, contact a healthcare practitioner first.
