You may have heard that when a doctor gives you an injection, they give you another medicine along with it. Or you may have heard of a medicine that helps to send a type of fluid under the skin when it is difficult to give saline into a vein in cases like dehydration. One medicine that is used in such cases and has a slightly special function is Hyaluronidase, which we are talking about today.
Simply put, what is Hyaluronidase?
Hyaluronidase is a protein that occurs naturally in our bodies. It is used as a medicine to enhance the effectiveness of other injectable medications, that is, to help those medications work.
Think of the tissue under your skin as a sponge. Sometimes it can be difficult for this sponge to absorb medications or liquids. This Hyaluronidase medication temporarily loosens the sponge, making it easier for other medications or liquids to spread and be absorbed into the body. This allows the other medication to work more quickly and effectively.
This medicine may also be used for other purposes. If you have any questions about it, you can ask your doctor. Vitrase is a well-known brand name for this medicine.
Things you should tell your doctor before taking this medicine
Before you are given this medicine, it is important that your medical team knows some things. Be sure to tell them if you have any of the conditions below.
- If you have allergies to bee or other insect stings.
- If there is any infection, wound, or swelling at the site where the vaccine is expected to be given.
- If you have ever had an unusual or allergic reaction to hyaluronidase, lamb protein, beef protein, thimerosal, or other medicines, foods, dyes, or preservatives.
- If you are pregnant , or trying to get pregnant.
- If you are a breastfeeding mother .
It is very important to tell your doctor about anything like this, because only then can they determine whether this medication is appropriate and safe for you.
