As a psychiatrist, I often discuss medications that can help manage various conditions, especially those related to substance use disorders. One such medication is naltrexone, an opioid blocker that is widely used for treating alcohol use disorder (AUD) and opioid use disorder (OUD). It can also play a role in chronic pain management and weight loss when combined with bupropion.

In this post, I'll explain how naltrexone works, its benefits, and important considerations for anyone taking it, especially in emergency situations.
