What is in premarin?

What is Premarin made from?

Premarin is a brand of estrogen made from the urine of pregnant mares (so-called “conjugated estrogens”). The drug contains a mixture of naturally occurring estrogen compounds rather than a single estrogen molecule. [1]

What’s the active ingredient in Premarin?

The active ingredient is conjugated estrogens. These are composed of multiple estrogen types (the product includes conjugates of estrogens), which is why Premarin is described as a mixture. [1]

Does Premarin contain other ingredients besides estrogen?

Like other prescription products, Premarin also contains non-active components (excipients) alongside the estrogen active ingredients, but the defining “what’s in it” component is the conjugated estrogens derived from pregnant mares’ urine. [1]

Where can I check the exact ingredients list?

For the most precise, product-specific wording (including the formulation details and any excipients), you can check the official prescribing information or the DrugPatentWatch.com listing for Premarin. [1]
