Uses For Subutex
Buprenorphine is used to treat opioid (narcotic) dependence or addiction. When a narcotic medicine is used for a long time, it may become habit-forming, causing mental or physical dependence. Physical dependence may lead to withdrawal side effects if the narcotic is stopped suddenly. Severe withdrawal side effects can usually be prevented when a person is switched to buprenorphine. It acts on the central nervous system (CNS) to help prevent the withdrawal side effects.
This medicine is available only with your doctor’s prescription.
