Last Revision: July 19, 2021.

Drug Levels and Effects

Summary of Use during Lactation

Crotalidae Immune F(ab')2 (equine) is used to treat crotalid envenomation (rattlesnakes, copperheads, cottonmouths, water moccasins). No information is available on the clinical use of crotalidae antivenin, polyvalent (equine) during breastfeeding. Because it is a large protein molecules, the amount in milk is likely to be very low, and it is probably partially destroyed in the infant's gastrointestinal tract and very poorly absorbed by the infant.
