[edit] Risk to pregnant women
According to the California Environmental Protection Agency, clobetasol propionate should not be used by pregnant women, or women expecting to become pregnant soon, as studies with rats shows a risk of birth defects (http://www.oehha.ca.gov/prop65/CRNR_notices/admin_listing/requests_info/referenced_docs/frpkg5r.html):
"Studies in the rat following oral administration at dosage levels up to 50 mg/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 abnormailities in fetuses): Pregnancy Category C: Clobetasol propionate 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. Clobetasol propionate has greater teratogenic potential than steroids that are less potent.There are no adequate and well-controlled studies of the teratogenic effects of clobetasol propionate in pregnant women. Temovate Cream and Ointment should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus."
