Hyalase® (Hyaluronidase) Injection Aftercare
Keep this aftercare leaflet safe and present it to the treating physician in the event of an adverse reaction.
Hyalase® is an enzyme which breaks down hyaluronic acid fillers, but it can also break down naturally occurring hyaluronic acid present in the body. The results can be unpredictable and the effect dramatic with possible loss of volume and some skin laxity. Although some of the effects can be immediate, it can take up to 2 weeks for the final results to be seen and the procedure may need to be repeated.
Hyalase® administration can result in anaphylaxis (a severe allergic reaction) which in itself is life-threatening and requires immediate medical attention.
Symptoms of a Severe Allergic Reaction
- Shortness of breath, wheezing, coughing
- Difficulty swallowing, swelling of the tongue, eyelids, lips
- Hoarseness of the voice
- Stomach pain, nausea or diarrhea
If you have any of the above symptoms, please report to your nearest Accident and Emergency Department or call 999 for an ambulance.
Common Injection-related Reactions
After the procedure, some other common injection-related reactions might occur. These reactions include:
- Redness, swelling, pain, itching, bruising and tenderness at the injection site
They have generally been described as mild to moderate and typically resolve spontaneously after a few days after injection. Bruising may occasionally be more significant.
If you have any concerns following treatment, do not hesitate to contact your treating practitioner on their emergency contact number.
