In the article on CroFab (june 25, 2001, vol. 43, page 55), the first sentence in the paragraph on Dosage should have been: "The antivenom should be given within six hours after the snakebite in an initial dose of four to six vials IV (depending on the severity of the bite) infused over 60 minutes."The dose does not depend on the size and age of the patient.

CroFab, an antigen-binding-fragment (Fab) antivenom of ovine origin, has been approved by the FDA for treatment of North American rattlesnake envenomation.
