  • Naltrexone Overview

    Naltrexone is used to prevent people who have been addicted to certain drugs (opiates) from taking them again. Naltrexone is used as part of a complete treatment program for drug abuse (such as compliance monitoring, counseling, behavioral contract, lifestyle changes). Naltrexone must not be used in people currently taking opiates, including methadone. Doing so can cause sudden withdrawal symptoms. Naltrexone belongs to a class of drugs known as opiate antagonists. It works in the brain to prevent opiate effects (such as feelings of well-being, pain relief). It also decreases the desire to take opiates. Ask your doctor or pharmacist if you should have naloxone available to treat opioid overdose. Teach your family or household members about the signs of an opioid overdose and how to treat it. Naltrexone is also used to treat alcohol abuse. It can help people drink less alcohol or stop drinking altogether. It also decreases the desire to drink alcohol when used with a treatment program that includes counseling, support, and lifestyle changes.

Naltrexone may be given as part of a program where a health care professional will watch you take the medication.

Naltrexone may be taken with food or antacids if stomach upset occurs. A urine test should be done to check for recent opiate drug use. Your doctor may give you another medication (naloxone challenge test) to check for opiate use. Do not use any opiates for at least 7 days before starting naltrexone. You may need to stop certain opiate drugs (such as methadone) 10 to 14 days before starting naltrexone. Dosage of Naltrexone is based on your medical condition and response to treatment. Your doctor may start you at a lower dose and monitor you for any side effects or withdrawal symptoms before increasing your dose. Take Naltrexone as directed. Do not increase your dose, take it more often, or stop taking it without your doctor's approval. Use Naltrexone regularly to get the most benefit from it.
