About Drug Allergies



Drug Allergy Test

Penicillin Allergy Testing


Allergic drug reactions occur when the immune system overreacts to a harmless substance in a drug that triggers an allergic reaction. Common drug allergies that produce an allergic reaction include:

  • Antibiotics, such as penicillin
  • Aspirin and non-steroidal anti-inflammatory medications, such as ibuprofen
  • Anticonvulsants
  • Monoclonal antibody therapy
  • Chemotherapy

Drug Allergy vs. Adverse Drug Reaction

Everyone responds differently to medications. One person may experience a troublesome side effect while another person may have no adverse reaction whatsoever. Drug side effects are common, but only 5% to 10% of drug reactions are caused by an allergy, which is why it’s important to get formal allergy testing and a proper diagnosis from an allergist if you suspect that you’re allergic to a certain drug.

If you suspect that you might be allergic to a medication that’s been prescribed by your doctor, be sure to call your doctor before altering or stopping your dosage.

Drug Allergy Symptoms

The most common drug allergy symptoms include:

  • Skin rashes, usually hives
  • Itching
  • Respiratory problems
  • Swelling, such as in the face

Serious allergic responses involve swelling, hives, lowered blood pressure, and anaphylactic shock in severe cases. These symptoms require immediate medical attention, and can be fatal if they’re not managed appropriately.

Drug Allergy Test

Drug allergy symptoms can be very similar to symptoms caused by other conditions. It can be difficult to determine if a reaction is caused by medication or something else. If you suspect that you have a drug or medication allergy, or if you’ve received an allergy diagnosis from a physician that’s not an allergist, it’s important to see an allergist and undergo a proper drug allergy test to confirm.

During a drug allergy test, Dr. Mehta will ask you to describe your symptoms, when symptoms began, and how long symptoms last. You should also be prepared to describe any other medications you were taking during the time of your reaction, including over-the-counter medications.

Penicillin drug allergy test

Penicillin Allergy Testing

Drug allergy misdiagnosis is very common, especially in the case of suspected penicillin allergy. As many as 90% of penicillin allergy diagnoses are actually misdiagnosed, preventing many individuals from taking penicillin antibiotics that could help them through common illnesses.

Standardized penicillin allergy testing is available and may be followed by an oral drug challenge in the clinic. Testing provides a high degree of certainty that penicillin and similar medications can be taken without allergic reaction.

Drug Allergy Treatment

Antihistamines, corticosteroids, and epinephrine may be prescribed in response to a serious drug allergy reaction.

The first step to overcoming a suspected drug allergy is to receive a proper diagnosis. Once diagnosed, Dr. Mehta can help you identify alternative medications that you’re not allergic to. If no alternative medication is available, the medication that you’re allergic to may be introduced in small doses until the therapeutic dose is achieved. This is called a desensitization procedure.

It’s important that you keep your other physicians, dentist, and pharmacy informed and up to date on your drug allergies.
