Disulfiram
Disulfiram is one medication that can help some people stop drinking. It works by interfering with the way your body breaks down alcohol. When you drink after taking disulfiram, a substance builds up in your body that causes a strong physical reaction. This reaction can include nausea, vomiting, sweating, chest pain, palpitations, headaches, dizziness, and even difficulty breathing. Because of how unpleasant these effects are, many people are deterred from drinking while on this medication.
Naltrexone
Naltrexone is another option that’s often prescribed for alcohol use disorder. It works by blocking the rewarding effects of alcohol in the brain, which helps reduce cravings and the urge to drink. It can also help people stay on track with their recovery, even if they slip up and drink a small amount.
Acamprosate
Acamprosate is a more recent medication used in alcohol treatment. It helps restore the balance of certain brain chemicals that are disrupted by long-term alcohol use. This can help reduce the desire to drink and support people in maintaining abstinence.
