Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Buprenorphine (Subutex) and naltrexone (Vivitrol) are both used to treat opioid use disorder, but they work in different ways and have different forms. Buprenorphine is a partial opioid agonist that helps ease cravings and withdrawal symptoms by attaching to opioid receptors in the brain, but it can still cause dependence and misuse. It is taken as a sublingual tablet that dissolves under your tongue. On the other hand, Vivitrol is an opioid antagonist that blocks opioid receptors, preventing the feel-good effects of opioids and alcohol. It is given as a monthly injection by a healthcare professional and does not have a risk of dependence or misuse. Buprenorphine is available as a lower-cost generic, while Vivitrol is only available as a brand-name medication. Common side effects of buprenorphine include headache and nausea, whereas Vivitrol can cause injection site reactions and nausea. Buprenorphine is a controlled substance, but Vivitrol is not.
