Pregnancy: No adequate and well controlled studies in pregnant women, and teratogenicity occurred at clinically relevant doses in rabbits and rats given the drug orally during pregnancy. Oral dosing in pregnant rabbits produced fetal malformations at 1.4 times the recommended human ophthalmic dose (spina bifida including meningocele), exencephaly and craniofacial malformations at 5.6 times, and abortion and embryofetal lethality at 83 times, with no developmental no-adverse-effect level established. Oral dosing in pregnant rats produced malformations at 34 times and embryofetal lethality at 695 times, with a developmental no-adverse-effect level of 3.4 times; in rats dosed from late gestation through lactation, survival of live-born offspring was reduced at 3.4 times. Background U.S. population risk is 2% to 4% for major birth defects and 15% to 20% for miscarriage.
Lactation: No data on presence in human milk, effects on the breastfed infant, or effects on milk production; weigh the developmental and health benefits of breastfeeding against the clinical need for treatment.
