    Summary

    A psychostimulant commonly used in the treatment of ADHD, narcolepsy and obesity, particularly in the EU instead of Adderall. Methylphenidate is also a 5HT1A receptor agonist. Sometimes prescribed off-label to help the withdrawals from cocaine and other stimulants.


    ⚠️ XR formulations become IR before they can be insufflated, so duration should be mostly the same.
