Mental Health Home > Generic Methadone

Methadone is often prescribed for the treatment of pain and addiction to opiates. Because all of the patents have expired, generic versions of the medication are available. There are several strengths and forms, including tablets, dispersible tablets, an oral solution, and injections. Several manufacturers make generic methadone, including Roxane Laboratories, Sandoz, and Mallinckrodt, Inc.

Is a Generic Version of Methadone Available?

Methadone hydrochloride (Diskets®, Dolophine®, Methadose®) is a prescription opioid medication. It is approved for treating pain and for opioid addiction treatment.
 
At this time, brand-name Diskets and Dolophine tablets are made by Roxane Laboratories, and Methadose tablets and oral concentrate are made by Mallinckrodt, Inc. However, the patents for methadone have long expired, and generic versions of all forms are available. In fact, both Roxane and Mallinckrodt are generic manufacturers.
