Applies to:Suboxone (buprenorphine/naloxone) and naltrexone
Using naltrexone together with buprenorphine is not recommended. Naltrexone can block the effects of buprenorphine and make the medication less effective in treating your condition. If you have been receiving buprenorphine for a while (for example, a week or longer), naltrexone can also precipitate withdrawal symptoms. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
