I've been asked a multitude of questions about drug allergies over the past 20 years. Most people do not get through life without having a side effect from a prescription drug or over the counter (OTC) medication. Adverse drug reactions occur when a medication causes a symptom or abnormal body function that is unintentional and potentially harmful. There are many types of adverse drug reactions but they are often classified as either allergic or non-allergic.
Allergic reactions to drugs are the result of the immune system responding to the medication as if it were a foreign invader (or germ). Symptoms and signs of drug allergy include: itching, rash, swelling, hives, wheezing, dizziness, fainting and fever or anaphylaxis (life threatening allergic reaction). But these are not the only possible signs/symptoms of allergic drug reactions. Some people may experience nausea, vomiting, diarrhea and abdominal pain. Unfortunately many of the above signs/symptoms may also occur in...

Penicillin allergy represents the most common drug allergy in the United States. Somewhere between one and 10 percent of people avoid penicillin because of a history of reacting to it. But did you know 80-90 percent of the time it may not be a true penicillin allergy? Yes, many people are labeled “penicillin allergic” but, in fact, are not allergic to this class of drug. Why is this?
Drug reactions are documented, in most cases, purely by the report of a patient having an adverse response to a medication. When someone experiences a rash, itching, upset stomach, diarrhea, abdominal pain, swelling, dizziness, lightheadedness, throat symptoms or shortness of breath while taking a medication, drug allergy is appropriately considered. Unfortunately, all it takes is the consideration for health providers to make the claim of drug allergy.
True drug allergies are mediated by an antibody that we all have, and is referred to as IgE . When our bodies gener...
