Drug Allergies

drug-allergies-allergy-allergist-top10mdAdverse drug allergies occur more often than you are aware of.

Drug allergies occur when your body responds in an unusual manner to medication.

Complications happen immediately or with time. It’s even possible to take a drug and be fine and then take it again later and then experience an allergic reaction.

The first time you take the medication prescribed for you, your body’s immune system may produce a substance, that works against the drug, called IgE. The next time you take the drug, the IgE tells your white blood cells to make a chemical called histamine. Histamine is what causes your allergy symptoms.

Most of the time you will suffer from a minor skin rash and/or hives the first time you take a drug that your body reacts to. Serum sickness is a delayed type of allergy that occurs a week or two after you have taken your medication. Penicillin and other antibiotics are the most common cause of drug allergies. Other common drugs people react to are anticonvulsants, insulin, x-ray contrast dyes and sulfa drugs.
