Understanding Phenytoin Equivalents

fosphenytoin image 1 (1)Sometimes, in an effort to make things simpler, we actually make them more confusing. Such is the case with phenytoin equivalents.

This week I received one from Dr. Scott Weingart that someone had sent to him. This paramedic was reviewing his anaphylaxis protocol with some new medics and providers. They asked a challenging question regarding a “pearl” they learned in which half-dose epinephrine should be administered in anaphylactic patients on beta-blockers. Patients on beta-blockers do have an increased risk for anaphylaxis, so there is a chance you’ll see a case just like this at some point.
