What is HYQVIA?
HYQVIA is an injectable drug containing a genetically designed protein. It is a dual vial unit with a vial of Immune globulin infusion 10% (Ig) and another vial of recombinant human hyaluronidase (Hy), which assists your body in the absorption of injectable medicines.
The parts are infused one after the other (Hy first, Ig second) through a needle set.
HYQVIA is an immune globulin infusion. It is a sterilized solution made up of human plasma containing antibodies that help your body to protect itself against different infectious diseases. It is used in treating primary immunodeficiency in adults.
HYQVIA is administered in the form of a subcutaneous infusion, given under the skin. It has flexible administration options in which a healthcare provider can teach you how to self-administer in the comfort of your own home.
Do not self-administer the medication if you do not understand the instructions properly. The infusion can also be administered at an infusion center.
- HYQVIA is to be stored in a refrigerator 36° to 46° for up to 3 years, (do not freeze the medication)
- It may be stored at room temperature (up to 77°F) for up to 3 months, during the first 24 months from the date of manufacturing printed on the carton.
- Do not return HYQVIA to the refrigerator if you take it out to room temperature.
- Store HYQVIA in its carton to protect it from light.
- The refrigerated product should be allowed to come to room temperature before use.
- Do not heat or microwave the product.
For infusion, an infusion pump is needed to titrate the appropriate flow rate. To prevent leakage at the infusion site while administering Hyqvia, a longer needle (12 or 14 mm) and using multiple infusion sites are considered.
- Before infusing, inspect the vials for any cloudy precipitates and do not shake the vials.
- Do not use the medication if the solution is not clear.
- Each vial is single-use and should not be used more than once.
- Suggested infusion sites are the thighs or abdomen.
- When infusing, do not mix the two medications given in the HYQVIA kit.
Both the components of HYQVIA are infused sequentially, starting first with Hyaluronidase then Ig 10% within 10 minutes through the same subcutaneous needle.
The entire contents of the Hyaluronidase vial are used for each full or partial vial of Ig infusion.
Local infusion-site reactions such as mild to moderate pain, temporary soft pancake-like swelling, itching, and skin redness are common.
Swelling may last 1-3 days and infusion-related reactions should go away in a few hours.
