What is the “Vivitrol pill” (and is it a real medication)?
“Vivitrol” is most commonly used online as a misspelling or confusion with either:
- Vivitrol as a brand name for injectable naltrexone (often discussed for alcohol or opioid use disorder), or
- Vivitrol Tablets that are sometimes mentioned in low-quality listings but are not the standard, widely recognized form for the medication most people mean.
The key point for search intent: there isn’t a commonly recognized, standard “Vivitrol pill” product the way there are for many other prescription drugs. The established medication associated with this name in mainstream prescribing is naltrexone, typically given as an extended-release injection for alcohol or opioid use disorder (brand names can vary by country and formulation).
If you tell me the exact spelling on the package (or whether it’s a tablet vs. injection) and your country, I can narrow down what you likely have.
If it’s actually naltrexone: what does it do and what is it used for?
Naltrexone is used to help with:
- Alcohol use disorder (to reduce heavy drinking)
- Opioid use disorder (to help prevent relapse)
It works by blocking opioid receptors, which reduces the rewarding effects of opioids and can reduce alcohol-driven reinforcement.
Why people look for a “pill” version
Extended-release naltrexone is often associated with injection formulations, so patients may search for a “pill” because they want something oral. Oral naltrexone tablets do exist in some markets, but that’s a different formulation and dosing schedule than the extended-release injection.
Can you take naltrexone if you’re on opioids?
This is a major safety issue people commonly run into when they search for the “pill.”
- Naltrexone can precipitate withdrawal in someone who still has opioids in their system.
- Clinicians typically require a period of opioid abstinence and may use urine testing before starting, depending on circumstances.
If you’re currently taking opioids (pain meds or anything else), it’s important to ask a prescriber/pharmacist before switching to any naltrexone product.
What side effects do patients ask about?
Commonly reported issues with naltrexone (tablet or injectable) include:
- Nausea, headache, dizziness
- Sleep problems
- Fatigue
- Injection-site reactions (for injections)
Liver safety matters too—naltrexone can affect liver enzymes, so prescribers consider baseline liver function and monitor when needed.
Could “Vivitrol pill” be a counterfeit or unapproved product?
If you found “Vivitrol” pills from an online shop, social media ad, or non-pharmacy source, there’s a risk the product is:
- misnamed,
- incorrectly labeled,
- or not what it claims.
A quick way to verify is to check whether it’s dispensed through a licensed pharmacy with a clear active ingredient (naltrexone) and a legible strength (mg).

Quick question so I can answer precisely
When you say “Vivitrol pill,” do you mean:
1) an oral tablet you were prescribed, or
2) the injection people sometimes associate with the name?
If you can paste the label text (active ingredient and strength) or describe the packaging, I’ll identify what it is and how it’s typically used.
