Do naltrexone and bupropion interact with other drugs?

Dr. Darria Long Gillespie, MD
Emergency Medicine
If you are taking bupropion, you should not take Contrave.

If you are taking an opioid, you should not take Contrave.

If you are taking amantadine, carbamazepine, efavirenz, levodopa, phenobarbital, phenytoin, or a protease inhibitor, Contrave may not be a good option for you.

You should not take Contrave while taking an MAO inhibitor or until at least 2 weeks after stopping MAO inhibitors.

If you have stopped drinking alcohol, taking a barbiturate, a benzodiazepine, an anticonvulsant, or an opioid in the past few weeks, you should not take Contrave.
