Hypersensitivity Reaction to Vitrase (Ovine Hyaluronidase)


The objective of this study was to rule out a greater than 10% incidence of hypersensitivity to Vitrase following a single intradermal injection of 3 USP units Vitrase. Less than or equal to 10% hypersensitivity response was considered acceptable.
