Vivitrol extended-release naltrexone
Vivitrol is a monthly injection of naltrexone. It is used for alcohol dependence in patients able to abstain before starting, and to prevent relapse to opioid dependence after detoxification. Those are different starting situations. The evaluation needs to establish which condition is being treated, whether withdrawal has been safely addressed and whether a month-long opioid blocker fits your health and pain-treatment needs.
How Vivitrol extended-release naltrexone works
Naltrexone blocks opioid receptors. For alcohol treatment, it can reduce alcohol-related reward and support a recovery plan. For opioid treatment, it blocks opioid effects. It does not relieve opioid withdrawal or treat dangerous alcohol withdrawal. Unlike buprenorphine, it is not an opioid agonist. It also does not protect someone who drinks from intoxication, impaired driving or alcohol poisoning.
Eligibility: Vivitrol extended-release naltrexone
For alcohol dependence, the first injection is for a patient who can abstain in an outpatient setting and is not actively drinking at administration. Every patient needs an opioid exposure review, even when alcohol is the reason for treatment. Pain medicines, tramadol, methadone, buprenorphine and opioid-containing cough or diarrhea remedies matter. Current opioid dependence, acute opioid withdrawal, a positive opioid urine screen or a failed naloxone challenge are label contraindications. Liver history and pregnancy require individual review.
What to expect: Vivitrol extended-release naltrexone
Check withdrawal and readiness
The clinician asks about the last drink, alcohol withdrawal history and recent opioids. Prior seizures, confusion or severe withdrawal may require medical withdrawal care before a relapse-prevention discussion. For opioid treatment, simply counting days since last use cannot prove that the injection is safe.
Review medicines and pain needs
Bring all prescriptions, nonprescription medicines and supplements. Discuss surgery, dental work, chronic pain and emergency pain plans. Naltrexone can block opioid analgesia. A negative urine result or a tolerated test does not guarantee that precipitated withdrawal is impossible, so the whole history matters.
Arrange the injection after clearance
A healthcare provider prepares Vivitrol and gives a deep intramuscular injection into the buttock. It is not a self-injection and is not interchangeable with an oral tablet. Oral naltrexone pretreatment is not required by the label, although the clinician may discuss prior experience or another supervised step.
Build continuing support
Discuss triggers, sleep, mood, counseling and what to do if drinking or opioid use returns. Set the next injection date and identify who handles a gap in medication delivery. Recovery needs can change even when injections are on schedule, so follow-up should assess life outside the appointment too.
Preparing for your appointment
Bring the last opioid and alcohol use dates, medication containers, detox/discharge records, previous naltrexone experience and liver test results if available. Be honest about any opioid exposure after the appointment was booked. Tell the clinician about prior injection reactions, bleeding concerns and pregnancy. Ask whether the appointment is an evaluation or a confirmed administration visit and how to contact the team if plans change.
Risks and when to seek help
Starting too soon after opioids can cause sudden, severe withdrawal that may need hospital care. The label generally recommends at least seven to ten opioid-free days after short-acting opioids; vulnerability after buprenorphine or methadone may last longer. Your clinician determines readiness. Never try to overcome the blockade with larger opioid amounts. Overdose risk rises as the injection wears off, after a missed dose or after stopping because opioid tolerance may be lower. Seek prompt assessment for worsening injection-site swelling, open wounds, jaundice, dark urine or severe abdominal pain. Call 911 for an overdose or another medical emergency.
Follow-up and treatment review
Vivitrol is usually given every four weeks or once a month. Contact the prescriber promptly if an injection is missed, especially if opioids were used during the gap. Re-starting still requires an opioid-free assessment. Report persistent cravings, alcohol use, depression and side effects; they are reasons to revisit the plan. Agree on access to naloxone or another suitable overdose-reversal medicine when opioid exposure is possible.
Appointments, costs and coverage
Ask what the estimate includes: evaluation, medicine, administration, tests and follow-up may be separate. Coverage authorization and medication arrival should be confirmed before the injection appointment is final. If treatment was started in another program, send the last injection date and records so care can continue safely. Confirm the administering site rather than assuming every evaluation location can give the injection.
Questions about your care
What is Vivitrol? Can Vivitrol be used for alcohol dependence?
Vivitrol is a monthly injection of naltrexone. It is used for alcohol dependence in patients able to abstain before starting, and to prevent relapse to opioid dependence after detoxification.

Pain medicines, tramadol, methadone, buprenorphine and opioid-containing cough or diarrhea remedies matter. Current opioid dependence, acute opioid withdrawal, a positive opioid urine screen or a failed naloxone challenge are label contraindications. Liver history and pregnancy require individual review.
How often are Vivitrol injections scheduled?
The labeled Vivitrol schedule is an injection every four weeks or once a month, given by a healthcare professional into the buttock muscle. Confirm the actual date and medication arrangement. Contact the prescriber after a missed visit; do not repeat or supplement treatment yourself.
Can Vivitrol be used for opioid use disorder?
Naltrexone blocks opioid receptors; it is different from buprenorphine, which partially activates them. Starting naltrexone while physically dependent on opioids can cause severe precipitated withdrawal. Vivitrol generally requires at least 7–10 opioid-free days after short-acting opioids; people transitioning from buprenorphine or methadone can remain vulnerable for up to two weeks. The clinician verifies readiness and the current label—do not stop opioids or choose a waiting period on your own.
Do you accept insurance for Vivitrol visits?
Have your insurance card ready when booking. Share member details through the clinic’s confirmed secure intake process. Check with the clinic and your insurer that the exact plan covers the clinician and requested service. Ask about visit charges, any separately billed tests or medicines, and any referral or authorization requirement. Coverage and your copay or deductible depend on the plan; request a written estimate if paying yourself.

Does Vivitrol make drinking safe or stop all cravings?
No. Cravings can persist, and alcohol can still cause intoxication, injury and poisoning. Tell the clinician if cravings or drinking continue so medication, behavioral support and level of care can be reconsidered. An injection is one part of treatment.
How long does Vivitrol last?
Vivitrol blocks opioid effects for approximately 28 days and is scheduled every four weeks or once a month. Drug release and the blocking effect gradually decline; the appointment date is not an exact point when the medicine is gone or opioids become safe. Overdose risk rises as blockade wanes, after a missed injection or after stopping because opioid tolerance may be lower. Never try to overcome the blockade. Contact the prescriber after a missed visit and discuss access to overdose-reversal medicine.
Is Vivitrol similar to methadone or Antabuse?
They can be used in substance-use treatment, but they work differently. Vivitrol is injectable naltrexone, an opioid antagonist used for alcohol dependence and opioid relapse prevention after detoxification. Methadone is a full opioid agonist used for OUD; it reduces opioid withdrawal and cravings. Antabuse is disulfiram, an alcohol-deterrent tablet that can cause an unpleasant and potentially serious reaction with alcohol. Vivitrol does not cause that disulfiram-type reaction, and drinking can still cause intoxication or alcohol poisoning. Switching from methadone to Vivitrol requires clinician-directed opioid-free preparation; do not switch or combine these medicines yourself.
Can you drink on Vivitrol?
Vivitrol is used with counseling and social support to help people avoid alcohol; it does not make drinking safe or treat acute alcohol withdrawal. The label requires being able to abstain before starting and not actively drinking at the first injection. If drinking returns during treatment, tell the clinician so the treatment and withdrawal-safety plan can be reviewed.
