The California Office of Environmental Health Hazard Assessment (OEHHA) has added clomiphene citrate to the Prop 65 list for chemicals known to cause cancer. Clomiphene citrate is better known by brand names Clomid, Milophene and Serophene and is used to stimulate ovulation in women. The listing is based on a formal requirement by a state of federal agency that the chemical be labeled or identified as a carcinogen or causing reproductive toxicity under the Health and Safety Code. The U.S. Food and Drug Administration (FDA) is the agency that filed the formal requirement. For more information on the listing of clomiphene citrate, visit OEHHA’s website.
