Can you become immune to modafinil?

Some people may have decreased efficacy from frequent use of Modalert 200mg, needing greater dosages to produce the same wakefulness-promoting benefits. Nevertheless, it is not advised to increase the dosage without medical supervision since this may result in dependency or adverse consequences. Although Modalert 200 is thought to have a minimal risk of addiction, frequent or prolonged usage should be closely watched by a medical expert. Tolerance can be avoided by taking pauses or using it sparingly.
