Official answer


Suboxone is a medication that combines the two drugs buprenorphine and naloxone. It is used to treat addiction to opioid drugs (like heroin) and prescription painkillers, including:

Buprenorphine, the active drug in Suboxone, is a partial opioid agonist. That means it works partially like an opioid, but its effects are weaker than drugs like heroin or methadone. It lowers the effects of withdrawal symptoms and reduces cravings for other opioids.

Naloxone is an opioid antagonist, or "blocker." It is only absorbed if Suboxone is injected instead of being dissolved in the mouth as prescribed. If injected, it causes uncomfortable withdrawal symptoms in order to discourage IV use.

Suboxone is safe and effective when used as prescribed, but it can cause serious side effects when used with many other medications. Drugs that can have negative effects when taken with Suboxone include:

It's important to tell your doctor about medicines you are taking while you're on Suboxone, including prescription drugs, over-the-counter medicine, vitamins and herbal supplements. Also avoid drinking alcohol, taking sedatives or other opioid pain medication, or using illegal drugs while on Suboxone.
