Suboxone is a pill that contains two different medicines, buprenorphine and naloxone. Subutex only contains buprenorphine. Buprenorphine is a medicine that is used to prevent the withdrawal symptoms people experience when they stop using opioid drugs. These symptoms can include depressed mood, anxiety, drug craving, nausea, diarrhea, vomiting, muscle and joint aches, muscle spasm, runny nose and eyes, sweating and difficulty sleeping. Naloxone is a drug that reverses the effects of opioids. It can cause withdrawal symptoms. Giving naloxone and buprenorphine together in Suboxone may make it easier to use each medicine properly.
“The study suggests that patients addicted to prescription opioid painkillers can be effectively treated in primary care settings using Suboxone,” however, once the medication was discontinued, patients had a high rate of relapse.
