Monthly cadence, not one-off treatment
The injection schedule is every four weeks, so the clinic choice needs to work for repeat follow-up and not just the first appointment.
A missed or stopped Vivitrol injection changes the follow-up and overdose-risk discussion. Contact the team before the due date if access is uncertain; do not try to overcome the blockade with opioids.
Give the actual date and any opioids used since then, including pain treatment. Restarting requires opioid-free assessment. A previous successful injection does not establish that the next administration is safe after an exposure change.
The label uses a monthly or every-four-weeks schedule and directs a missed dose as soon as possible. Supply, clinical review and administration still have to be coordinated. A late appointment should trigger a next-step discussion rather than silently ending care.
Opioid tolerance can be lower near the end of a dosing interval and after missed or stopped treatment. Returning to a previous amount or attempting to override blockade can cause overdose. Keep naloxone and an emergency response plan.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Ask the selected service for the next available appointment for Vivitrol assessment. Confirm whether booking or a walk-in visit is appropriate before traveling. The first visit reviews eligibility, records and the treatment plan. Medication delivery, authorization and an injection appointment may need separate coordination.

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.
The injection schedule is every four weeks, so the clinic choice needs to work for repeat follow-up and not just the first appointment.
Patients using Vivitrol for alcohol dependence should already be able to abstain and should not be actively drinking at the first injection.
Patients using Vivitrol for opioid use disorder usually need to be opioid-free for 7 to 14 days before the first injection, and the team confirms readiness before scheduling administration.
Because the injection is monthly, delays, no-shows, and schedule gaps should be addressed early instead of assumed from the previous calendar.
