Which companies make fluoxetine (and where is it produced)?
Fluoxetine (the active ingredient in products such as Prozac) is manufactured in multiple countries by different companies, depending on the specific brand, strength, and supplier for that market. This ingredient is produced through contract manufacturing and API (active pharmaceutical ingredient) supply chains that can vary over time.
What determines where your fluoxetine dose was made?
Where a particular fluoxetine package was manufactured often depends on:
- The marketing authorization holder and the finished-dose (tablet/capsule) manufacturer for your country.
- The specific batch/API supplier used for that lot.
- Changes in manufacturing sites due to supply contracts, approvals, or regulatory updates.
How can you check the exact manufacturing location for your bottle?
The most reliable way is to check your medication’s labeling (often near the “Manufactured by”/“Mfd by” line and/or the manufacturer address, sometimes tied to the specific lot). If you share the text from your label (company name and the line that lists the manufacturing site), I can help interpret it.
What should you do if you need verification for a purchase or study?
If you’re doing research, quality documentation, or a regulated procurement, ask the supplier/pharmacy for:
- The finished product manufacturer name and address shown on the package/COA
- Lot number-specific documentation (Certificate of Analysis)
- Proof of where the finished dosage form was manufactured
