A Proprietary Technology
Hylenex recombinant (hyaluronidase human injection) is a purified preparation of the enzyme recombinant human hyaluronidase made using sophisticated recombinant DNA technology in a U.S. facility compliant with the FDA’s current Good Manufacturing Practices (cGMP).

Indication:

Hylenex® recombinant (hyaluronidase human injection) is an endoglycosidase indicated as an adjuvant to increase the dispersion and absorption of other injected drugs.

Important Safety Information:

Contraindications
Hylenex recombinant is contraindicated in patients with known hypersensitivity to hyaluronidase or any of the excipients in Hylenex recombinant. Discontinue Hylenex recombinant if sensitization occurs.

Warnings and Precautions
Spread of Localized Infection: Hyaluronidase should not be injected into or around an infected or acutely inflamed area because of the danger of spreading a localized infection.
Ocular Damage: Hyaluronidase should not be applied directly to the cornea. It is not for topical use.

Adverse Reactions
Allergic reactions have been reported in less than 0.1% of patients receiving hyaluronidase. Anaphylactic-like reactions following retrobulbar block or intravenous injections have occurred, rarely.
The most frequently reported adverse reactions have been mild local injection site reactions, such as erythema and pain. Hyaluronidase has been reported to enhance the adverse reactions associated with co-administered drug products.

Drug Interactions
Furosemide, the benzodiazepines, products containing sodium metabisulfite (e.g. in local anesthetic products containing epinephrine) and phenytoin are incompatible with hyaluronidase.
Hyaluronidase should not be used to enhance the dispersion and absorption of dopamine and/or alpha agonist drugs.
When used with local anesthetics, hyaluronidase hastens the onset of analgesia and shortens its duration of effect, and increases the incidence of systemic reactions.
Patients receiving large doses of salicylates, cortisone, ACTH, estrogens or antihistamines may require larger amounts of hyaluronidase for equivalent dispersing effect.

Available by prescription only.
