Who makes Premarin (conjugated estrogens)?
Premarin is a brand of conjugated estrogens (used for estrogen replacement in certain patients). The specific manufacturer can vary by country and by the particular Premarin product strength/formulation. For the most accurate answer for your location and dosage form, check the label (active ingredient and “manufactured for/by” line) on your specific box.
What manufacturer details should you look for on the box or prescription label?
Look for the “Manufactured for” or “Manufactured by” line and any company name followed by an address. This is the fastest way to confirm the current distributor/manufacturer for the exact Premarin product you have (tablet strength can matter for sourcing).
Is the manufacturer the same as the “brand owner”?
Not always. A drug brand may be owned by one company, while the tablets or formulation can be manufactured (or relabeled) by a different manufacturer under contract. The box label usually shows the actual manufacturing company tied to that lot.
If you tell me your country and product strength, I can narrow it down
If you share:
- your country (or where the prescription was filled), and
- the Premarin strength (e.g., 0.3 mg, 0.625 mg, etc.) and dosage form (tablet),
I can help pinpoint the likely manufacturer listed for that specific product.
