Buprenorphine — Uses, Dosage, Side Effects & Safety

Drug class: Opioid partial agonist

Overview

Buprenorphine is a prescription medication used to treat opioid dependence (addiction to opioid drugs) and to manage moderate to severe pain. It works by binding to opioid receptors in the brain, reducing cravings and withdrawal symptoms in people with opioid use disorder, while producing less euphoria and respiratory depression than full opioid agonists. For pain management, buprenorphine provides relief by altering the way the brain and nervous system respond to pain. It is available in several forms, including sublingual tablets/films, transdermal patches, and injections. Patients should know that buprenorphine can help reduce opioid misuse, but it must be used exactly as prescribed to avoid dependence, overdose, or withdrawal.
