Drug allergies are an abnormal reaction of your immune system to any medication either over-the-counter, prescription, or herbal. However certain medications are more likely to induce a drug allergy than the others.
The most common symptoms and signs of a drug allergy include fever, rashes or hives but serious reactions including a life-threatening condition can also be caused to affect multiple body systems.
The side-effect of a drug that may be listed on the label cannot be considered similar to a drug allergy. It is also different from drug toxicity which is caused by an overdose of the medication.
It only takes an hour for the signs and symptoms of a serious drug allergy to become evident after the drug is ingested. Some reactions like rashes can occur hours, days, and even weeks after. Some of the signs and symptoms of a drug allergy may include skin rash, itching, hives, fever, shortness of breath, swelling, runny nose, wheezing, and itchy and watery eyes.

Research suggests that drug allergies may be overdiagnosed or that patients may report reactions that have never been confirmed. Drug allergies that are misdiagnosed may result in the use of inappropriate medication or expensive drugs.

They may also conduct allergy skin testing by administering a tiny quality of the suspected drug into the skin with a small needle that scratches the skin, an injection or a patch. A positive reaction to the test will cause an itchy, red, or raised bump. It also suggests that the patient may have a drug allergy.
