Educational Information Only

This site is for education only and is not a substitute for medical advice, diagnosis, or treatment. Always speak with a qualified, licensed clinician before making any decisions about medication or treatment. Naltrexone is a prescription medication and is not appropriate for everyone.

This page is not a substitute for medical evaluation. Only a qualified, licensed clinician can determine whether naltrexone and the Sinclair Method are appropriate for you. This page is intended to help you understand the general considerations so you can have a more informed conversation with a clinician.

Who May Be a Good Candidate

  • Adults who drink regularly and want to reduce or stop drinking
  • People who experience strong alcohol cravings
  • People who have tried to cut back and found it difficult
  • Gray-area drinkers, binge drinkers, and high-functioning drinkers
  • People who want a medication-assisted approach
  • People who do not want to commit to immediate lifelong abstinence
  • People who have not responded well to other approaches

Who Should Be Cautious or May Not Be Candidates

  • People currently using opioids — naltrexone will precipitate withdrawal in people who are opioid-dependent
  • People with significant liver disease — naltrexone is metabolized by the liver; liver function should be evaluated
  • People who are pregnant or breastfeeding — discuss with a clinician
  • People with acute hepatitis
  • People who need opioid pain medication — naltrexone blocks opioid effects
  • People with severe alcohol withdrawal risk — medical supervision is essential

Questions to Ask a Clinician

  • Am I a candidate for naltrexone given my medical history?
  • Do I need a liver function test before starting?
  • Are there any medications I take that interact with naltrexone?
  • What dose would you recommend?
  • How will we monitor my progress?
  • What should I do if I experience side effects?

Talk to a Licensed Clinician
