Generally, anxiety is not treated with modalert 200 (modafinil). Some people may even have increased anxiety or restlessness or uneasiness as a result of taking it, particularly if they are stimulant sensitive or take larger amounts. In addition to improving attention, modafinil Modalert 200 encourages wakefulness and alertness, which some users may experience as negative side effects including irritation or increased stress. Its effects on anxiety are little understood, however it may help boost energy levels and lessen weariness and mood. It's advisable to speak with a healthcare provider if you're experiencing anxiety because stimulants like Modalert are seldom used to treat anxiety; instead, SSRIs or therapy are usually used.
