Drug Levels and Effects

Summary of Use during Lactation

Crotalidae polyvalent immune Fab (Ovine) is used to treat crotalid envenomation (rattlesnakes, copperheads, cottonmouths, water moccasins). No information is available on the clinical use of Crotalidae polyvalent immune Fab during breastfeeding. Because it is a large protein molecule, 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.
