What is Campral?
Campral affects chemicals in the brain that may be unbalanced in a person who is addicted to alcohol. Acamprosate works by restoring this chemical balance in the brain in an alcohol-dependent person who has recently quit drinking.
Campral is used to help maintain sobriety in alcohol-dependent adults who no longer drink alcohol. This medicine is used with behavioral therapy or counseling support to help prevent an urge to drink again. Campral will not treat or prevent alcohol withdrawal symptoms.
Campral may not be as effective if you have not gone through detox and stopped drinking alcohol completely. This medicine is also unlikely to be effective in people who abuse drugs or other substances.
