Some healthy persons may think about using Modalert 200mg for cognitive enhancement, alertness, or to remain awake. It is typically given for disorders like narcolepsy, sleep apnea, or shift work sleep disorder.  But it's crucial to remember that Modalert 200 is a prescription drug, and taking it unsupervised might result in negative side effects including headaches, sleeplessness, and anxiety.  It is not advised for healthy people to consume it for an extended period of time as this might result in abuse or dependency.  Additionally, it is yet unclear if Modalert is safe and beneficial for improving cognitive function in healthy people.  Before taking any drug off-label, it's advisable to speak with a healthcare professional.
