Subutex is the trade name given to a semi-synthetic opioid, known as Buprenorphine. It was specifically manufactured to treat the withdrawal symptoms in people recovering from the opioid addiction. The drug relieves the withdrawal symptoms and thus, helps in preventing a relapse. Its mechanism of action is similar to other opioids such as morphine and heroin. It is also used for the treatment of moderate to severe pain. Similar to other opioids, prolonged use of Subutex can develop the tolerance, which can lead towards addiction. The drug also has a high potential for abuse, misuse, and overdose. Accidental exposure in children can be fatal. The misuse during pregnancy can lead to neonatal opioid withdrawal syndrome; that can be life-threatening. The medicine comes with a proper guide and instructions to avoid the cases of overdose. It was discovered in 1970 and was labeled as a very harmful medicine if used incorrectly.
