Yes, Modalert 200 is a brand name for a medication called Modafinil. It's primarily prescribed to treat sleep disorders like narcolepsy, obstructive sleep apnea, and shift work sleep disorder. Modafinil is known for its wakefulness-promoting effects and is sometimes used off-label to enhance cognitive function in conditions like ADHD or for boosting alertness and focus in individuals without sleep disorders. However, it's important to use it only under a doctor's supervision due to potential side effects and dependency issues.
