Why injectors plan around it
HA filler is reversible, and hyaluronidase is the reversal agent. That reversibility is one reason HA products are widely used, and it is why emergency preparedness for filler centers on having the enzyme on hand, knowing how it is used, and having a written protocol for events like vascular occlusion.
Prescription, protocol and training
Hyaluronidase is a prescription product. Using it requires an order or protocol from a qualified prescriber, and the person using it must be trained for the situation. Using it to dissolve filler is generally an off-label use of the product, which is why the written protocol and documentation matter (see off-label use).
Practices that perform HA filler should be able to show what is stocked, where it is kept, who may use it, the dosing approach in their protocol, and when staff were last trained.
Having it ready
Practices that inject hyaluronic acid filler typically keep hyaluronidase on site with a written protocol, so the team knows who does what if a vessel is affected. Dosing and technique should be learned in training, not on the day it is needed.
Common mistakes
- Not stocking it, or letting it expire.
- No written plan for who acts and when.
- Assuming it resolves every type of complication.
Frequently asked
Can all fillers be dissolved with hyaluronidase?
No. It works on hyaluronic acid fillers. Other filler types, such as calcium hydroxylapatite or poly-L-lactic acid, are not reversed this way.
Is hyaluronidase only for emergencies?
No. It is also used to correct unwanted filler results such as lumps or a bluish tint. The decision to use it is a clinical one made under the practice's protocols.
