Patient Education - Aspirin "Allergy" or Sensitivity

Aspirin (acetyl-salicylic acid or ASA) may cause allergy-type reactions in persons who develop this unusual sensitivity. Although this sensitivity is not a true allergy (see What is Allergy?), this idiosyncratic type reaction can be very serious - sometimes even life-threatening. Another type of idiosyncratic reaction (occurring infrequently in sensitive persons) is that caused by intravenous contrast dye used for CAT Scans. Those people who have both moderate to severe asthma and chronic sinusitis are more likely to be aspirin sensitive. The main types of reactions are:

Stomach pains due to aspirin are not allergic or idiosyncratic types of reactions, but are usually due to irritation of the stomach lining.

One very important point is that most NSAID's (or Non-steroidal anti-inflammartory drugs) cross-react with aspirin - meaning that they can cause the same types of reactions in aspirin sensitive people. These drugs are mostly used for arthritis and other painful disorders. Common NSAID's (not a complete list) include: Advil, Anaprox, Ansaid, Butazolidin, Clinoril, Dolobid, Feldene, Ibuprofen, Indocin, Motrin, Naproxyn, Nuprin, Orudis, Rufen, Tolectin, and Voltaren. AS FAR AS OVER-THE-COUNTER MEDICATIONS FOR ACHES AND PAINS - LOOK ON THE LABEL.. THERE SHOULD BE A WARNING ABOUT THOSE ALLERGIC TO ASPIRIN.

A drug commonly used for aches and pains is Acetaminophen (Tylenol™, e.g.) Acetaminophen, however, is very commonly safe in aspirin sensitive people when used at recommended doses. As with all medication decisions, you should discuss this with your doctor. An allergy specialist may also find other pain or arthritis medications that you could try under close supervision.

ASPIRIN (acetyl salicylic acid or ASA) and NSAID's are found in many home remedies, over-the-counter (OTC) drugs, and prescription medications. Please check the list below. THIS IS NOT A COMPLETE LIST AS NEW PREPARATIONS ARE BEING ADDED ALL THE TIME. Look for ASA (aspirin) in medications for headaches, colds, coughs, allergies, sinus problems, arthritis, rheumatism (joint pain), menstrual cramps, stomach acidity, backache, or urinary pain. Please read all labels carefully, or ask the pharmacist before trying any medication. An over-the-counter medication label may say in small print "don't take this medicine if you are allergic to aspirin or NSAID's." Also, remember to tell your doctor, dentist, and nurse that you are sensitive to aspirin.

Artificial coloring, for example Tartrazine Yellow (FD&C No. 5), may rarely mimic aspirin sensitivity. This dye is present in many foods including alcoholic and soft drinks, candies, artificial orange juice (TANG), luncheon meats, preserves, jams, fruit gelatins, ice cream, colored baked goods, toothpaste, and mouth wash. Always read the labels on packaged foods and try to avoid those that contain this artificial coloring if you're sensitive to aspirin.

Tartrazine dyes are also present in some medicines including some antihistamine preparations used to treat allergies. Use only those medications prescribed by your doctor, and be suspicious of any colored pills if you develop an itch, rash, or stuffy nose after you start taking them.
