Ketamine Pregnancy and Breastfeeding Warnings

Ketamine is also known as: Ketalar

Ketamine Pregnancy Warnings

Ketamine has not been formally assigned to a pregnancy category by the FDA. Animal studies at higher than human doses failed to reveal evidence of teratogenicity or impairment of fertility. There are no controlled data in human pregnancy. Since the safe use in pregnancy and delivery has not been established, the manufacturer recommends that ketamine be considered contraindicated in pregnant women. Ketamine has been assigned to pregnancy Risk Factor B by Briggs et al. as probably compatible.

Ketamine Breastfeeding Warnings

There are no data on the excretion of ketamine into human milk. Because ketamine is a general anesthetic agent, breastfeeding would not be possible during use of the drug. According to Briggs et al., ketamine should be undetectable in maternal plasma approximately 11 hours after a dose. Nursing after this time should not expose the infant to significant amounts of the drug.
