Methadone is a synthetic opioid medication or drug, which is commonly prescribed as a treatment and harm reduction approach for opioid use disorder, in particular, to help people overcome heroin addiction. A powerful painkiller, methadone is also sometimes prescribed to treat severe pain. The main therapeutic effects of methadone are to reduce heroin withdrawal symptoms, prevent heroin and other opiates from producing euphoria and reduce pain perception. Methadone can appear as a tablet, powder, or liquid, and is typically administered as a measured oral dose in the form of a green syrup, or in a sweet orange or cherry flavored drink. Methadose, a relatively new methadone formula, is ten times stronger than methadone, requiring a much smaller dose to be given.
