DRUG ALLERGY SYMPTOMS

A drug allergy is the abnormal reaction of your immune system to a medication. Any medication is capable of inducing a drug allergy. This reaction can cause varieties of mild to severe allergic symptoms such as rash, fever, or Steven-Johnson Syndrome and trouble breathing. In some cases, drug allergy may cause serious reactions, including a life-threatening condition that affects multiple body systems (anaphylaxis). It’s important to know if you have a drug allergy and what to do about it.
