Published January 20, 2025 · 8 min read · Updated April 2026

Reviewed for accuracy by licensed clinical professionals.

Three FDA-approved medications treat opioid use disorder. Each works differently and suits different situations.

Suboxone (buprenorphine)

Partial opioid agonist. Prevents withdrawal and reduces cravings. Can be started during withdrawal. Prescribed by any physician. Daily sublingual film or tablet. Mild abuse potential. Safe overdose profile due to ceiling effect.

Methadone

Full opioid agonist. Prevents withdrawal and blocks other opioid effects. Daily dosing at licensed clinic initially. Most effective for severe, long-standing OUD. No waiting period before starting. Higher overdose risk than buprenorphine.

Vivitrol (naltrexone)

Opioid antagonist. Blocks all opioid effects. Monthly injection. Requires 7-14 days opioid-free before starting. No abuse potential. Best for highly motivated patients who have completed detox.

Choosing

No universal best option. Suboxone: flexibility, safety, wide access. Methadone: strongest coverage for severe OUD, daily structure. Vivitrol: monthly dosing, zero abuse potential, requires detox first. Your provider helps determine the best fit.
