A drug allergy may cause serious reactions, including a life-threatening condition that affects multiple body systems (anaphylaxis).A drug allergy is not the same as a drug side...

Once your immune system detects a drug as a harmful substance, it will develop an antibody specific to that drug. This can happen the first time you take a drug, but sometimes an allergy doesn't develop until there have been repeated exposures.The next time you take the drug, these specific antibodies flag the drug and direct immune system attacks on the substance....
