Modalert Pills are primarily used to treat excessive daytime sleepiness caused by sleep disorders such as narcolepsy, shift work sleep disorder, and obstructive sleep apnea. They contain modafinil, a wakefulness-promoting agent that helps improve alertness, focus, and mental clarity. Doctors prescribe Modalert Pills to support patients who struggle to stay awake during normal daily activities. While they do not cure underlying sleep conditions, they help manage symptoms and improve quality of life. Modalert Pills should always be taken under medical supervision to ensure safe and effective use.
