NALTREXONE SUSPENSION - INJECTION
COMMON BRAND NAME(S): Vivitrol
WARNING: Naltrexone can cause liver problems when given in large doses. Stop using this medication and tell your doctor immediately if symptoms of liver problems develop (e.g., persistent nausea, unusual tiredness, abdominal/stomach pain, yellowing eyes/skin, pale stools, dark urine).
This medication should not be used in patients who already have liver problems (e.g., active hepatitis, liver failure). (See also Side Effects section.)
USES: This medication is used to treat alcohol abuse. It is used only in people who have been able to stop drinking for some time before starting treatment with naltrexone. You should not be drinking when you start naltrexone. It can help people drink less alcohol or stop drinking altogether. Naltrexone works in the brain to decrease the desire to drink. It does not work like some other treatments for alcohol abuse (e.g., disulfiram). It will not make you sick when taken with alcohol.
This medication is also used to prevent relapse to opioid abuse, after opioid detoxification. It works by blocking the action of opioids. This medication 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 is used as part of a complete treatment program for alcohol or opioid abuse (e.g., counseling, 12-step program, lifestyle changes).
HOW TO USE: Read the Medication Guide provided by your pharmacist before you start using naltrexone and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Before you receive this medication, you should have a urine test 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 alcohol/any opiates for at least 7 days before starting naltrexone.
This medication is injected into a muscle in the buttock as directed by your doctor, usually once a month.
Dosage 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.
If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. The mixed medication is milky white. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.
Do not increase your dose or use this drug more often or for longer than prescribed. Do not stop taking this medication without consulting your doctor.
To get the most benefit from this medication, use it regularly and continue your treatment program. To help you remember, mark your calendar with the days you need to receive this drug and/or be treated.
