Commissioner Jane E. Henney, M.D.
Food and Drug Administration

(get address)

Dear Commissioner Henney:

     As an American taxpayer and an animal lover, I am writing to request that the FDA require pharmaceutical companies to disclose the source of estrogens used in the manufacturer of Premarin and other non-synthetic hormone replacement therapies.  Specifically, I urge you to require that:

• All packaging for Premarin and similar products, including repackaged bottles and other containers issued by pharmacies, be clearly labeled as containing estrogens derived from horse urine.

• At the very least, all physicians’ and patients’ information inserts for Premarin and similar products specify that these drugs are derived from the urine of pregnant mares.

     As you know, these estrogens are indeed derived from pregnant mares’ urine and thousands of mares are exploited to produce these drugs and thousands of their foals are slaughtered annually.

     Women should be able to make informed choices.  That is why I request your immediate action to require new labeling requirements for Premarin.

Sincerely,
