Red blood cells provide oxygen to body tissues.Normally, red blood cells last for about 120 days in the body. In people with hemolytic anemia, red blood cells in the blood are destroyed earlier than normal.In some cases, a drug can cause the immune system to mistake your own red blood cells for foreign substances. The body responds by making antibodies to attack the body's own red blood cells. The antibodies attach to red blood cells and cause them to break down too early.Drugs that can cause this type of hemolytic anemia include:Cephalosporins (a class of antibiotics), most common cause Dapsone Levodopa Levofloxacin Methyldopa Nitrofurantoin Nonsteroidal anti-inflammatory drugs (NSAIDs) Penicillin and its derivatives Phenazopyridine (Pyridium) Quinidine Drug-induced hemolytic anemia is rare in children.
