Modafinil how long does it last ?

Half life of Modafinil 200mg in healthy individuals is 12-15 hours after which you will experience its effects fading away.

If you have an underlying kidney or liver disease, this can slow down the metabolism of Modafinil in your system and prolong its half-life.

Although half life is about 15 hours, traces of Modafinil can still be found in your system until day 4 or more since last dose, even though the stimulant effects wear off.

Traces of Modafinil can still be found in your system until hour 82 after the last dose. Modafinil is less likely to be confused with stimulants like Adderall or other recreational drugs during a drug test.

If tested for traces of Modafinil in your system it will show up until a few days from the last dose.
