How much medicine you take and how often you take it depends on many factors, including the condition being treated and the age and weight of the patient. If you have any questions about the amount and/or frequency of Revia (naltrexone) you are taking, talk with your health care provider. Carefully read the information provided with Revia (naltrexone) and reread it each time you get this prescription refilled. Take Revia (naltrexone) exactly as prescribed by your health care provider.

Do not use narcotics while taking Revia (naltrexone), including opioid-containing medicines (such as cough and cold products, pain relievers, or heroin). It may cause coma or death.

If more than one dose is missed, contact your doctor or pharmacist.
