Do you also get sick frequently? Sometimes our body's immune system can become weak due to various reasons. When that happens, even a minor illness that a normal person gets can become more severe for you, or you may get infections frequently. So, in such cases, today we are going to talk about a special treatment that doctors recommend to help the body's defense system.
What is this medicine? Let's understand it simply.
This is actually a combination of two medications. Let's look at them separately.
1. Immune Globulin: This is the main drug. Simply put, this is a collection of antibodies collected from the blood plasma of a large number of healthy people. Antibodies are like part of our own army that fights germs that enter our body. So, if your body is producing less of these antibodies, when these antibodies that are given from outside enter your body, they give you a lot of strength to fight germs. That is, this helps to prevent you from getting infections or reduce the severity of them if you do get them.
2. Hyaluronidase: This is a protein that is naturally present in our body. Its function is to help the body absorb the medicine called `Immune Globulin` mentioned above under the skin. It is like someone paving the way. This allows the main medicine to enter the body more efficiently.
The combination of these two drugs is most commonly known by the brand name `HYQVIA`.

Other things that may interact with this medicine
The main thing that can interact with this medicine is live virus vaccines . For example, measles, mumps, and rubella (MMR) vaccines.
Imagine, the antibodies you receive from outside with this `Immune Globulin` medicine fight against the weakened live virus in the vaccine and inactivate it. Then, the immunity expected from the vaccine will not develop in your body.

Also inform your doctor about any other medications, vitamins, or traditional medicines you are taking.
