According to the California Environmental Protection Agency,<unk>  should not be used by pregnant women, or women expecting to become pregnant soon, as studies with rats shows a risk of birth defects: "Studies in the rat following oral administration at dosage levels up to 50 mcg/kg per day revealed that the females exhibited an increase in the number of resorbed embryos and a decrease in the number of living fetuses at the highest dose. Pregnancy: Teratogenic Effects (i.e., possibility of causing abnormalities in fetuses): Pregnancy Category C:<unk>  has not been tested for teratogenicity when applied topically; however, it is absorbed percutaneously, and when administered subcutaneously it was a significant teratogen in both the rabbit and mouse.<unk>  has greater teratogenic potential than steroids that are less potent. There are no adequate and well-controlled studies of the teratogenic effects of<unk>  in pregnant women. Temovate Cream and Ointment should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus."
