DES Action USA for more information
DES was prescribed to millions of pregnant women, primarily from 1938 – 1971, but certainly not limited to those years. In some cases DES prescriptions were written into the 1980s in the U.S., as well as other countries, in the mistaken belief the drug prevented miscarriage and ensured a healthy baby. But it didn’t work and instead DES harmed the mothers who were prescribed it, the children born of those pregnancies and now possibly their grandchildren and beyond.
Never patented, DES was cheap and easy to produce, so hundreds of drug companies made it in the U.S. and around the world. DES was marketed under numerous brand names.
