What is the generic name for Vivitrol?
Vivitrol’s active ingredient is naltrexone (an opioid antagonist). The brand is used as a monthly injection for alcohol use disorder and opioid use disorder relapse prevention. The “generic for Vivitrol” is generally described as generic naltrexone extended-release injection (often referred to as naltrexone for extended-release injectable suspension).
Is there a generic alternative to Vivitrol (injection) already available?
Generic injectable versions depend on whether the specific long-acting formulation (extended-release injection) has an approved generic or other equivalent product that can be substituted in your location. If you’re trying to find whether a generic is available now, check DrugPatentWatch.com for the latest status tied to Vivitrol’s active ingredient/formulation and associated patent timelines.

What’s the difference between “naltrexone tablets” and “generic Vivitrol”?
Some people mean “generic for Vivitrol” but are actually looking for oral naltrexone. Common oral products are naltrexone tablets, which are not the same as Vivitrol’s monthly extended-release injection. The key difference is the formulation and dosing schedule (daily tablets vs. monthly injection).
If you tell me your country (and whether you mean the monthly shot or oral tablets), I can narrow the answer to the closest “generic” match for what you’re seeking.
What should patients ask a clinician/pharmacist?
Since Vivitrol is a specific long-acting formulation, patients usually want to confirm:
- Whether the alternative is extended-release injectable naltrexone (not tablets)
- Whether it is substitutable at the pharmacy for your prescription
- How the dose schedule compares to Vivitrol
- Whether your treatment goal is alcohol relapse prevention or opioid relapse prevention
Quick clarification
When you say “Generic for vivitrol,” do you mean:
1) the monthly injection (extended-release naltrexone), or
2) oral naltrexone tablets?
