Methylphenidate: Ingestion methods

Last modified: Saturday, 20. June 2009 - 12:57 pm

MPH is most often taken in pill form. It is available in prescribed quantities of 5-, 10-, and 20-mg tablets. A sustained or delayed release 20-mg tablet is also available. In 2001, the FDA approved Concerta, a longer acting MPH tablet that is taken once a day. Besides its long lasting action, Concerta has another benefit: Abusers sometimes grind MPH tablets into a powder and snort it up their noses, but Concerta is formulated so that it cannot be ground into a powder. According to the DEA, methylphenidate abusers also dissolve the immediate-release MPH tablets in water and then inject the mixture.
