Why is Campral prescribed?

Campral is prescribed to treat alcohol dependence. It helps people who have already stopped drinking alcohol keep from starting again.

You must be alcohol-free before taking Campral for it to work. You must also be prepared to follow a complete alcohol treatment plan that includes mental and behavioral health counseling.

Campral is thought to work by restoring and regulating brain chemicals that have been disrupted by long-term exposure to alcohol. Campral is not used for any type of substance dependence other than alcohol.
