What is Campral?
Campral (acamprosate) 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 together with behavior modification and counseling support to help a person who has recently quit drinking alcohol continue to choose not to drink.
Campral is not likely to be helpful if you have not already quit drinking or undergone detoxification. It may not help you if you are also addicted to other substances besides alcohol.
Campral may also be used for purposes not listed in this medication guide.
You should not use Campral if you have severe kidney disease.
Campral can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
