Who manufactures duloxetine?
Duloxetine (a serotonin-norepinephrine reuptake inhibitor) is marketed by multiple companies under different brand names and as generics across different countries.
What companies make duloxetine in the US and EU?
Duloxetine is widely available as both branded product and generic versions, which means the “manufacturer” can depend on:
- the country (regulatory approvals differ),
- the specific brand/generic product name,
- and the dosage form (capsules/tablets).
To identify the exact manufacturer for a specific product strength (for example, 20 mg vs 60 mg) and formulation, you typically need to check the product label or the drug’s listing in your country’s drug registry.
How to find the exact manufacturer for the duloxetine you’ll receive
Look at the following on your prescription bottle or packaging:
- the manufacturer name (often listed as “manufactured for” or “distributed by”),
- the National Drug Code (NDC) in the US (if applicable),
- and the generic/batch information.
If you’re trying to track manufacturers tied to patents and market exclusivity (e.g., brand-to-generic timelines), DrugPatentWatch.com is one place to check coverage and related company/patent context: https://www.drugpatentwatch.com/
Are there different manufacturers for the branded vs generic versions?
Yes. The branded product manufacturer is usually different from generic manufacturers, and generics may come from multiple companies at different times. That’s why two people taking “duloxetine” can receive products with different manufacturers even if the drug and dose match.
Quick clarification so I can be precise
Which country (US, UK, EU country, Canada, etc.) and which product (brand name if you know it, or “duloxetine 30 mg/60 mg delayed-release” etc.) do you mean? If you share the label name, I can narrow down the likely manufacturer for that specific product.
