Medications for alcohol use disorder are effective and safe for most people, and most insurance plans cover them. Yet only a small share of people who could benefit are ever offered one.

Naltrexone

Naltrexone reduces cravings and makes drinking less rewarding, which can cut down heavy drinking days. It comes as a daily pill or a monthly injection (Vivitrol). You can’t take it with opioid medications, and it isn’t right for some people with significant liver disease.

Acamprosate

Acamprosate helps people who have already stopped drinking stay stopped, by easing the restlessness, anxiety and poor sleep of early recovery. It’s taken three times a day, and the dose is adjusted for kidney function.

Disulfiram

Disulfiram (Antabuse) causes flushing, nausea and a racing heart if you drink. It only works when taken every day, so it suits people who are highly motivated and have someone supporting them.

Other options

Clinicians sometimes prescribe medications such as topiramate or gabapentin off label when the FDA-approved options aren’t a fit. The right choice depends on your goals, other medications and health history.

Your goal can be cutting back or stopping

Some people want to quit completely. Others want to drink less. Medication can help with either goal, and it works best alongside therapy or peer support.

A gentle next step

Wellthy Psychiatry offers judgment-free, LGBTQ+ affirming care by telehealth across California. A free 15-minute phone consult is an easy way to see if we’re a good fit.
