How Your Body Rejects a Biologic
Biologics are a type of medication that are made from living organisms, such as proteins or cells. They are used to treat a variety of diseases, including cancer, rheumatoid arthritis, and Crohn's disease.
While biologics can be very effective, they can also cause side effects, including injection site reactions, rash, and fever. In some cases, the body can also reject a biologic. This is called an immune response.
How does the immune response work?
The immune system is the body's natural defense against infection. It is made up of a network of cells, tissues, and organs that work together to identify and destroy foreign substances, such as bacteria and viruses.
When the body is exposed to a biologic, the immune system recognizes it as a foreign substance. It then produces antibodies, which are proteins that bind to the biologic and mark it for destruction. The immune system also activates T cells, which are specialized white blood cells that can kill cells that have been marked by antibodies.
In some cases, the immune response to a biologic can be very strong, and the body can quickly reject the medication. This is called an anaphylactic reaction. Anaphylaxis is a life-threatening condition that requires immediate medical attention.
What are the symptoms of a biologic rejection?
The symptoms of a biologic rejection can vary depending on the severity of the reaction. Some of the most common symptoms include:
* Injection site reactions, such as pain, redness, and swelling
* Rash
* Fever
* Chills
* Nausea
* Vomiting
* Diarrhea
* Shortness of breath
* Dizziness
* Confusion
What should I do if I experience symptoms of a biologic rejection?
If you experience any symptoms of a biologic rejection, it is important to see your doctor right away. Your doctor will evaluate your symptoms and determine if you are experiencing an immune response to the medication. If you are experiencing an anaphylactic reaction, you will need to be treated with epinephrine (adrenaline) and other medications.
How can I prevent a biologic rejection?
There is no sure way to prevent a biologic rejection, but there are some things you can do to reduce the risk, such as:
* Tell your doctor about any allergies you have
* Tell your doctor about any other medications you are taking
* Be aware of the symptoms of a biologic rejection and see your doctor right away if you experience any of them
Biologics are a powerful class of medications that can be very effective in treating a variety of diseases. However, it is important to be aware of the potential risks, including the risk of an immune response.
