Applies to hyaluronidase: injectable powder for injection, injectable solution

Local

Local reactions are the most common side effects. The most common side effect during hypodermoclysis is edema.[Ref]

Other

Hyaluronidase (the active ingredient contained in Hydase) increases the side effects of coadministered drugs.[Ref]

Hypersensitivity

Hypersensitivity reactions have included urticaria and angioedema in less than 0.1% of patients. Anaphylactic-like reactions have rarely been reported after intravenous or retrobulbar injection.[Ref]

One clinic has reported a possible increase in cases of angioedema related to the use of pharmacy-compounded hyaluronidase in cataract surgery as opposed to that seen with the use of manufactured products.[Ref]

Ocular

Ocular side effects have included case reports of hypersensitivity reactions after retrobulbar injections, which manifested as increased intraorbital pressure and swelling, periorbital edema, and localized pruritus.[Ref]
