Acamprosate for Alcohol Abuse and Dependence
|Generic Name||Brand Name|
How It Works
Experts are still studying how this medicine works. It appears to reduce cravings for alcohol by helping balance brain chemicals called neurotransmitters. It also might reduce anxiety, mood swings, and sleep problems caused by alcohol withdrawal.1
Why It Is Used
Acamprosate was approved by the U.S. Food and Drug Administration (FDA) to treat alcohol dependence in people who have quit drinking. This medicine is used to reduce cravings for alcohol, and it might help with anxiety and other problems caused by withdrawal. It can be used along with some other medicines.
How Well It Works
During trials, side effects didn't bother most people who took acamprosate. Diarrhea was the most common side effect. Some people had belly pain, nausea, vomiting, headache, drowsiness, rash, itching, flatulence, or dizziness. A very small number of people who took the medicine had an increase in suicidal thoughts or had serious kidney problems.2
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
People who have kidney problems might not be able to take this medicine or might need to take lower doses.
In addition to medicines, counseling can also help you stop drinking. You might also want to attend a support group, such as Alcoholics Anonymous (AA).
