Drug-induced immune hemolytic anemia is a condition where the immune system destroys the red blood cells. This takes place in response to medication. The resulting low red blood cell count is known as anemia.
Red blood cells transport oxygen to tissues of the body. In some people, medications can cause the immune system to attack and destroy red blood cells. This is known as hemolysis.
Hemolytic anemia brought on by an immune reaction to a drug can be caused by a number of medications. Examples include many types of antibiotics and certain blood pressure drugs, among others.
