Whether you can take Modalert 200mg daily depends on why it was prescribed and your doctor's guidance. Modalert (modafinil) is sometimes prescribed for regular daily use in conditions such as Narcolepsy, Obstructive Sleep Apnea (to address residual sleepiness), or Shift Work Sleep Disorder. However, taking it daily without medical supervision is not recommended. Regular use may increase the risk of side effects such as headache, insomnia, anxiety, elevated heart rate, or changes in blood pressure. Your doctor can determine the appropriate dose, schedule, and monitoring based on your health history. If you're considering daily use, it's best to discuss it with a healthcare professional rather than starting or continuing it on your own.
