What Is Vivitrol and How Does It Help With Recovery?

Vivitrol is the brand name for extended-release naltrexone, an FDA-approved monthly injection used to treat opioid use disorder and alcohol use disorder. It is one of the three medications considered gold standard for medication-assisted treatment (MAT).

If you are in Virginia weighing your MAT options, this guide explains what Vivitrol actually is, how it works in the brain, who qualifies, what the risks are, and what it costs in Hampton Roads.

What Vivitrol Is and How Monthly Injections Work

Vivitrol is a 380 milligram intramuscular injection administered once every 4 weeks. It is manufactured by Alkermes and has been FDA-approved for opioid use disorder since 2010 and alcohol use disorder since 2006.

The active ingredient is naltrexone in an extended-release polymer. After injection, naltrexone releases steadily into the bloodstream over approximately 28 to 30 days. Blood levels remain relatively stable throughout the month, which is the main advantage over daily oral naltrexone (ReVia).

The injection is given in the gluteal muscle by a licensed provider. Most patients tolerate the injection well. Some experience mild soreness at the injection site for a few days.

How Vivitrol Blocks Opioid and Alcohol Effects in the Brain

Vivitrol works by binding to the brain's mu-opioid receptors. When naltrexone occupies these receptors, opioids like heroin, oxycodone, or fentanyl cannot bind. The euphoria that reinforces continued use does not happen.

For alcohol, the mechanism is related but not identical. Alcohol triggers endorphin release in the brain's reward system. Endorphins bind to mu-opioid receptors. Vivitrol blocks this reinforcement pathway, which reduces alcohol cravings and heavy drinking.

The clinical result: on Vivitrol, using opioids produces no high, and drinking alcohol produces significantly less reward. The brain has less reason to seek out either substance.

Who Is a Good Candidate for Vivitrol Treatment

Vivitrol works well for specific patient profiles:

• Patients who have completed medical detox and are opioid-free for at least 7 to 14 days
• Patients who prefer a monthly injection over daily medication
• Patients concerned about adherence to daily dosing
• Patients with co-occurring alcohol use disorder
• Patients in professions where controlled substances create licensure concerns (medical, aviation, law enforcement)
• Patients transitioning out of residential treatment
• Patients on probation or in drug court programs

Vivitrol is not the right first choice for patients still using opioids, patients unable to complete a detox period, or patients with severe chronic pain requiring opioid pain management.

The Importance of Being Fully Detoxed Before Starting

This is the most critical clinical point. Vivitrol requires 7 to 14 days completely opioid-free before the first injection.

Starting Vivitrol while any opioids are still in the system causes precipitated withdrawal. The naltrexone displaces opioids from receptors and blocks them. The result is sudden, severe withdrawal that can last hours to days. This is one of the worst experiences in addiction medicine.

Providers use a urine drug screen before administering Vivitrol. Some providers also use a naloxone challenge test to verify no opioids remain in the system. If you have used long-acting opioids like methadone or fentanyl, the washout period may need to be longer than 14 days.

Comparing Vivitrol to Daily Oral Naltrexone

Naltrexone is available in two forms:

Vivitrol (monthly injection). Consistent blood levels for 28 days. No daily adherence required. Administered by a provider. Cannot be missed accidentally.

Oral naltrexone (ReVia, generic). Daily 50 milligram tablet. Requires daily patient adherence. Less consistent blood levels. Significantly less expensive.

Research consistently shows better adherence and lower relapse rates with the monthly injection than with the daily pill. This is not because the medication is different. It is because monthly dosing eliminates the daily decision of whether to take the medication.

Oral naltrexone can still be a reasonable choice for patients with strong adherence support or cost concerns. Vivitrol is generally considered the first-line naltrexone option when accessible.

Availability and Cost of Vivitrol in Hampton Roads Virginia

Vivitrol is widely available at licensed MAT providers, specialty pharmacies, and some primary care offices throughout Hampton Roads.

Retail cost is approximately 1,500 to 1,700 dollars per monthly dose without insurance. However, coverage and support programs significantly reduce this:

• Virginia Medicaid (Cardinal Care) covers Vivitrol with no out-of-pocket cost for eligible enrollees
• Tricare covers Vivitrol for military beneficiaries
• Anthem, UnitedHealthcare, Aetna, and Cigna typically cover Vivitrol under Virginia Code § 38.2-3412.1
• The Alkermes Vivitrol Co-Pay Program can reduce out-of-pocket cost to as little as 5 dollars per dose for eligible commercially insured patients
