Sold under the brand name “Hyqvia”, the combination of Hyaluronidase and immune globulin is used to treat primary immunodeficiency in adults. Based on the definition posted on drugs.com, Hyaluronidase is “used as an aid in helping your body absorb other injected medications”. As for Immune globulin, it “contains the antibodies to help your body protect itself against infection from various diseases”. Before using this treatment, it is very important that you tell your doctor if you have other health issues, such as diabetes, kidney/ heart disease, or if you use birth control pills. You should also tell them if you’ve ever been bed-ridden due to severe illness. And considering the fact that it is still unclear whether or not the Hyaluronidase-immune globulin combination could harm the fetus or the nursing baby, telling your doctor that you are pregnant / breastfeeding before taking this medicine is highly recommended. It is worth noting that the drug in question is typically injected under the skin, once every four weeks. Listed as follows are the common side effects of Hyaluronidase-immune globulin combination (and they’re quoted from drugs.com): headache, fever, tiredness, nausea, and vomiting. There are, however, other side effects that require medical attention such as liver problems, lung problems, chest pain, flu symptoms, and sudden weakness on one side of the body, among others. Don’t forget to call your doctor if you experience any of the aforementioned side effects.
