Revia is an orally administered medication used to treat alcohol and opioid dependence. It contains the active ingredient naltrexone. Naltrexone belongs to a class of drugs called opiate antagonists, which work in the brain to prevent opiate effects such as pain relief and feelings of well-being. In addition to blocking these effects, Revia also reduces the desire to take opiates.
Revia 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. It is often used in combination with other treatments, such as counseling and support groups, to help people overcome their addiction.
Uses and Dosage
Revia is an oral tablet that should be taken by mouth with or without food, usually 50 milligrams once daily, or as directed by your doctor. In some cases, a health care professional may watch you take the medication as part of a program and may order a higher dose of 100-150 milligrams to be taken every 2-3 days to make it easier to schedule clinic visits. If stomach upset occurs, this medication may be taken with food or antacids.
Before starting naltrexone, a urine test should be done to check for recent opiate drug use. Your doctor may also give you another medication, known as a naloxone challenge test, to check for opiate use. Do not use any opiates for at least 7 days before starting naltrexone, and you may need to stop certain opiate drugs, such as methadone, for 10 to 14 days before starting naltrexone.
The dosage of Revia is based on a patient's medical condition and response to treatment. Doctors may start patients at a lower dose and monitor them for side effects or withdrawal symptoms before increasing their dosage. Patients should take tablets as directed and should not increase their dose, take it more frequently, or stop taking it without their doctor's approval.
To get the most benefit from Revia, patients should use it regularly and take it at the same time every day. They should inform their doctor if they start using drugs or alcohol again.
