What is naltrexone?
Naltrexone is a daily prescription pill (also available as a monthly injection) that has been FDA-approved to treat alcohol use disorder since 1994. It is not a controlled substance and is not addictive.
How does naltrexone work for drinking?
Naltrexone blocks the opioid receptors involved in alcohol's pleasurable 'reward.' Over time, drinking feels less rewarding, which can make it easier to cut back or stop. In a JAMA meta-analysis of 122 trials, oral naltrexone reduced the return to heavy drinking (number-needed-to-treat of 12).
How do I get naltrexone online?
With Abstinex, you complete a structured intake and safety screening from home. A licensed clinician reviews your case and, when appropriate, may prescribe naltrexone. Nothing is prescribed automatically — a clinician makes every decision. Care starts at $99; no insurance is required.
Naltrexone for moderation or for quitting
Naltrexone can support either goal — drinking less or stopping entirely. Your goal guides how your clinician plans your care.
