Bexarotene topical Pregnancy Warnings

Animal studies of oral administration during days 7 to 17 of gestation in rats showed developmental abnormalities including incomplete ossification at 4 mg/kg/day, cleft palate, microphthalmia, and small ears at 16 mg/kg/day, and developmental mortality at 10 mg/kg/day. The rat no-effect oral dose is 1 mg/kg/day. Bexarotene plasma levels after topical application in chronic T-cell lymphoma (CTCL) patients were usually less than one hundredth of the rat dysmorphogenesis-associated Cmax, although some patients reached levels approximately one eighth the dysmorphogenesis Cmax. There are no controlled data in human pregnancy.

Pregnancy categories A, B, C, D, and X are being phased out.
