Many people take drugs without a doctor’s advice ignoring the fact even common drugs like aspirin and ibuprofen can produce allergic reaction. Most of us might have experienced unintended reaction when take medicines. 15 to 30 % of drugs would produce reactions. But only 1of 10 drug reactions are true allergy.

Drug reaction

Drug reactions can be classified into two.

1 Common and predictable reaction of a drug. These expected side effects may be due to interaction between two medicines or due to excessive intake of medicine-over dosage.

2. Unpredictable reaction of a drug. These reactions are seen only in certain people. This includes unexpected side effects, medication intolerance, allergic reactions and other non allergic immunologic reactions.

True Allergic Reactions

When you take medicine for the first time no reaction is experienced.

1. There would not be any problem if medicine is taken for a period of time (1 week) or one week before medicine is taken again.

2. Reaction is different from expected side effect.

3. The reaction is suggestive of anaphylaxis- low blood pressure, rapid heart rate, trouble breathing and skin symptoms like swelling

4. Symptoms disappear within few days if medication is stopped.


Skin rashes-urticaria and angeoedema- are common symptom in medication allergy. But sun burn like lesions is suggestive of non allergic immunologic origin. Low blood pressure, rapid heart rate and short breath may be present. Allergy can be developed to any medicine but some common medicines are

1. Penicillin-It is very life threatening reaction. Skin test can be done to identify it.

2. Cephalosporin-Persons who have allergy to penicillin can develop allergy to this medicine also.

3. Sulfonamides-No conclusive test is available for this drug

4. Anti inflammatory drug-Non steroidal anti inflammatory drugs like aspirin, ibuprofen and naproxen can produce allergy. But there is no reliable test for them.


1. Avoidance of suspected medicines is most important. All that is needed is that you have to tell your doctor details about the allergic drugs.

2. Immediate treatment like injection of epinephrine is essential for anaphylaxis.

3. Consult allergist to determine the cause

4. If one medicine is allergic replace it with other medicine to cure the disease.

5. Desensitizing treatment can be done. Small dose is given initially with increasing doses over many hours.
