Who makes Lybalvi (olanzapine + samidorphan)?
Lybalvi is a brand-name drug made by Alkermes (U.S. label/brand), combining olanzapine and samidorphan in a single product. The active ingredients are an antipsychotic (olanzapine) plus an opioid antagonist/add-on component (samidorphan).
Is there a generic “Lybalvi” (olanzapine + samidorphan)?
You generally won’t see a true generic substitution for Lybalvi until there is an approved generic (or interchangeable) product specifically containing the same combination at approved dosing.

What counts as a “generic” here—single-ingredient vs combination?
A lot of “generic olanzapine” confusion comes from the fact that:
- Generic olanzapine tablets are widely available.
- But Lybalvi is not just olanzapine; it is the fixed combination of olanzapine + samidorphan.
So even if olanzapine generics are on shelves, that does not mean there is a generic Lybalvi-equivalent combination product.
If you’re trying to switch, the key question is whether the substitute contains both components (olanzapine and samidorphan) in the same formulation.
How to verify a manufacturer or label claim for the product you’re seeing
If you’re searching for “manufacturer generic,” the practical step is:
- confirm the exact product name and strength on the pharmacy label (Lybalvi vs generic olanzapine),
- then verify the manufacturer listed for that specific NDC/product.
Because generic combination products (if/when they exist) can come from different manufacturers than the brand, manufacturer identity depends on the exact product.
What to check if you’re trying to predict when a generic might launch
Generic timing for combination products usually depends on:
- patent life for key formulations/uses,
- any method-of-use protections,
- exclusivity periods (if applicable).

Quick clarification question
When you say “manufacturer generic,” do you mean:
1) the company that makes the brand Lybalvi, or
2) the company that makes an available generic/alternative to Lybalvi (olanzapine + samidorphan)?
If you share the country (U.S. vs elsewhere) and the exact product strength/NDC (if you have it), I can narrow the answer to the likely manufacturer for that specific product.
