Generic Name: naltrexone (nal-TREX-one)
Brand Name: Revia

Revia is used for:

Treating alcoholism and narcotic (opioid) addiction in adults, as part of a complete treatment program. It may also be used to treat other conditions as determined by your doctor.

Revia is a narcotic antagonist. It is thought to work by blocking the effects of opioids (eg, heroin, narcotic pain relievers). It has also been shown to decrease alcohol consumption.

Do NOT use Revia if:

  • you are allergic to any ingredient in Revia
  • you are currently dependent on narcotics or you are having withdrawal symptoms from narcotics
  • you are taking narcotic pain medicines (eg, codeine), opioid medicines to treat narcotic addiction (eg, methadone), or a lab or medical test shows you have opioids in your system
  • you have hepatitis or liver failure

Contact your doctor or health care provider right away if any of these apply to you.

  • Thioridazine because side effects such as sleepiness and sluggishness may occur.
  • Medicines that may harm the liver (eg, acetaminophen, methotrexate, ketoconazole, isoniazid, certain medicines for HIV infection) because the risk of liver side effects may be increased. Ask your doctor if you are unsure if any of your medicines might harm the liver.

This may not be a complete list of all interactions that may occur. Ask your health care provider if Revia may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
