Cysteamine ophthalmic Pregnancy Warnings

Use during pregnancy is recommended only if the potential benefit justifies the potential risk to the fetus.

US FDA pregnancy category: C

Animal studies have revealed evidence of teratogenicity and fetotoxicity. Teratogenic findings included cleft palate, kyphosis, heart ventricular septal defects, microcephaly, and exencephaly; fetotoxicity resulted in intrauterine death and growth retardation. This drug reduced the fertility of adult animals and the survival of their offspring at an oral dose 1.7 times the recommended human dose (RHD), but had no effect on fertility and reproductive performance at an oral dose 0.4 times the RHD. There are no controlled data in human pregnancy.

US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
