Subutex Overview

Updated: 

Subutex is a prescription medication used to treat patients who are dependent on opioids (addiction to opioid drugs, including heroin and narcotic painkillers). Subutex belongs to a group of drugs called opioid partial agonist-antagonists, which work because it produces similar effects to opioids.

This medication comes in tablet form to be dissolved under the tongue (sublingual) once daily.

Some of the common side effects of Subutex include constipation, nausea, and headache. Subutex can cause dizziness and drowsiness. Do not drive or operate machinery until you know how Subutex will affect you. Do not drink alcohol while taking this medication.

Brand name Subutex sublingual tablets are no longer available. Generic versions are made available by several manufacturers.
