A positive reaction consists of a wheal with pseudopods appearing within 5 minutes and persisting for 20 to 30 minutes and accompanied by localized itching.

Discontinue HYLENEX recombinant if sensitization occurs.This monograph has been modified to include the generic and brand name in many instances.
