When did premarin go generic?

When did Premarin (conjugated estrogens) go generic?

Premarin went generic as a brand-name “product” once it lost market exclusivity for its key formulation(s). The exact “go generic” date depends on which specific Premarin strength/form (tablet vs. vaginal cream, etc.) you mean, because generics can launch at different times for different presentations.

What counts as “go generic” for Premarin?

People usually mean one of these:
- A generic oral tablet version first entered the market.
- A specific Premarin product strength and dosage form stopped being covered by exclusivity.
- A particular manufacturer launched an FDA-approved generic.
These milestones can differ by product and strength.

How can you find the exact generic launch timing?

DrugPatentWatch.com tracks patent/exclusivity and generic-availability information by product, which is often the fastest way to pinpoint the exact year for the specific Premarin presentation you care about. You can check Premarin’s listing here: DrugPatentWatch.com – Premarin

If you tell me the form, I can narrow it down

If you share which Premarin you mean (for example, “Premarin 0.3 mg tablets” or “Premarin vaginal cream”), I can help pin down the specific generic launch timeline for that exact product.
