Campral is used as part of a complete treatment program that includes both counseling and psychological support.

Revia is also used to treat narcotic drug addiction.

Campral (acamprosate calcium) works by restoring the natural balance of chemicals in the brain (neurotransmitters) and is used to help alcohol-dependent patients keep from drinking alcohol. Campral should be used as part of a complete treatment program that includes both counseling and psychological support. Campral is unlikely to be helpful to a person who has not already quit drinking or undergone detoxification. Campral may not be helpful to a person who is also addicted to other substances besides alcohol.

Revia (naltrexone) is a special narcotic drug that blocks the effects of other narcotic medicines and alcohol used to treat narcotic drug or alcohol addiction and is taken orally in tablet form.

There may be other drugs that can interact with Campral. Tell your doctor about all your prescription and over-the-counter medications, vitamins, minerals, herbal products, and drugs prescribed by other doctors. Campral should be used only when prescribed during pregnancy. Drinking large amounts of alcohol during pregnancy can cause long-lasting problems (often called fetal alcohol syndrome) in your baby, such as birth defects, growth retardation, and learning disabilities. It is not known whether this drug passes into breast milk. Consult your doctor before breastfeeding.

Revia may interact with narcotic drugs or alcohol, or prescription or over-the-counter medicines to treat a cold, cough, diarrhea, or pain. Tell your doctor all medications and supplements you use.

The recommended dose of Campral is two 333 mg tablets (each dose should total 666 mg) taken three times daily.

To treat alcoholism, a dose of 50 mg Revia once daily is recommended for most patients. To treat opiod dependence, the initial dose of Revia is 25 mg.
