Three medications are currently approved in the US for the treatment of alcohol use disorder and can be prescribed by any clinician: Naltrexone (Revia®, Vivitrol®), Acamprosate (Campral) and Disulfiram (Antabuse®). Naltrexone and acamprosate are very safe and well tolerated and do not make people sick if they drink but rather work to decrease cravings and urges to drink to help people drink less. They are both available in pill form, however, naltrexone is also available as a monthly injection that some patients prefer for ease of adherence. Disulfiram is one of the first medications used to maintain abstinence from alcohol however it is rarely prescribed now. People who were medicated with disulfiram would feel immediately sick if they had even a small amount of alcohol. This approach has fallen out of favor.
