Immune globulin therapy, which first occurred in the 1930’s, is “the use of a mixture of antibodies (immune globulins) to treat a number of health conditions” (Wikipedia.com) According to another source, “immune globulins are given to those with a weak immune system to strengthen or act as the body’s natural immune system.” Additionally, they decrease the risk of infection in these patients, especially the ones who are incapable of making antibodies due to their immune deficiency. Considering the fact that immune globulins are part of the human blood’s plasma, they can be separated out when people donate blood. Then, they are given to the patient through an injection into their vein in order to help strengthen their immune system and, of course, their ability to fight off infections. Bear in mind that Immune globulins can cause blood clots in people with certain pre-existing conditions such as diabetes, kidney problems, strokes, and heart problems. So, make sure you tell your doctor about your other health issues before using this treatment. It is worth noting that Immune globulins can cause dizziness, nausea, headache, fever, and chills – All of which may even occur during the injection itself. There are also other side effects that require immediate medical care such as kidney/lung problems, blood clot, and dehydration. Remember to tell your doctor if you are pregnant before taking these injections as they may not be safe for you.
