Drug Name: Revia (Naltrexone)

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.

Use Revia as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Take Revia by mouth with or without food.
• Revia should not be taken until the naltrexone challenge test is negative.
• Before taking Revia , you must be willing to take Revia to help with alcohol dependence, you must be free of substance abuse for 7 to 10 days, you must not have any severe or active liver or kidney problems, and you must not have any other medical problems or conditions that make taking Revia inadvisable.
