Drug Allergies Directory
Some drugs trigger allergic reactions in certain people. This happens when the body believes the drug is a foreign substance that is dangerous. The body tries to attack the drug with histamine and other substances in order to expel it from the body. Some of these allergic reactions can be life-threatening, while others may cause itchy skin, hives, congestion, or other less serious symptoms. Penicillin is a very common drug allergy. Treating drug allergies mostly consists of symptom relief, but for serious reactions, epinephrine may be given.
