Revia (Naltrexone) from Maple Leaf Medications.

Revia (naltrexone) Indications

Revia, generic name naltrexone, is a medication used to treat alcohol and opioid dependence.

Naltrexone acts by blocking the effects of opioids and alcohol in the brain by binding to opioid receptors in the brain, blocking the effects of opioids such as heroin, morphine, and codeine. In addition, naltrexone can reduce the rewarding effects of alcohol, which can help reduce the urge to drink.

Revia is used as part of a comprehensive treatment program that includes counselling, support, and other forms of therapy to help people overcome addiction. While Revia is not a cure for addiction, this medication is a tool to help manage cravings and reduce the risk of relapse.

Revia (naltrexone) Uses and Dosage

Prior to starting Revia, read the prescription information leaflet carefully to understand the dosing instructions and potential side effects. Always take Revia exactly as prescribed by your healthcare provider.

The recommended dosage of Revia depends on the condition being treated. The recommended dose for managing alcohol dependence is 50 mg once daily. The recommended dose for the treatment of opioid dependence is typically 50 mg once daily, yet in some cases the dose may be reduced to 25 mg once daily.

Revia tablets are swallowed whole with a full glass of water at the same time each day, usually with food to help reduce the risk of stomach upset.
