Snake antivenin administration in a patient allergic to horse serum.

We have described a case in which a potent epinephrine drip was useful in the management of a patient who needed antivenin and was allergic to horse serum. With 50 ml of 1:10,000 epinephrine in 500 ml of 5% dextrose in water, repeated anaphylactoid reactions were controlled. We believe that such a solution would be helpful in other patients having severe anaphylactic reactions to antivenin.
