What is acamprosate used for?

Acamprosate helps curb alcohol cravings and is prescribed to individuals who have already quit drinking.³ It is not used to treat withdrawal symptoms or for those still consuming large amounts of alcohol.¹ 

 

Acamprosate is commonly part of medication-assisted treatment (MAT), combining medication with behavioral therapy to support recovery.³ 

How does Acamprosate work?

The exact mechanism is unclear, but it is believed to restore neurotransmitter balance (GABA and glutamate) in the brain, reducing cravings and preventing relapse.⁷

Dosage and treatment plan

The typical dose is 666 mg (oral, slow-release tablet) taken three times daily. Tablets should be swallowed whole. Taking them with meals may help with adherence.³

Acamprosate vs. Naltrexone: Which Is Right for You?

Both medications treat alcohol use disorder but function differently: 

  • Acamprosate: Targets brain chemistry to reduce cravings and prevent relapse.⁸ 
  • Naltrexone: Blocks the brain's pleasure response to alcohol, reducing heavy drinking.⁸ 

 

Unlike acamprosate, naltrexone also treats opioid use disorder and is available in tablet or injection form. However, naltrexone has more side effects, including dizziness and fatigue.⁴ 

 

A meta-analysis found that acamprosate is better for maintaining abstinence, while naltrexone is more effective for reducing heavy drinking and cravings.⁵ 

 

Your doctor will help determine the best option based on your needs and health history.
