What you need to know about Drug Allergies

A drug allergy is an abnormal reaction of your immune system to a medication. A drug allergy occurs when your immune system identifies (sometimes mistakenly) a drug as a harmful substance, and as such develops an antibody specific to that drug.

Symptoms of drug allergy ranges from having a rash or fever to having serious reactions, including a life-threatening condition called anaphylaxis which affects multiple body systems. The symptoms may occur right away or hours after receiving the drug.

Please note that a drug allergy is not the same as an already known and expected drug side effect.

Which drugs most often cause an allergic reaction?

Although any drug can cause an allergic reaction, some drugs are more commonly associated with allergies than the rest. They include:

  • Antibiotics such as penicillin

While anyone can have an allergic reaction to a drug, a few factors can increase the risk of having one. These may include:

  • A history of other allergies like food, dust or pet allergy

An Allergic reaction can cause symptoms such as:

  • Itchy skin or eyes

Treatment

The goal of treatment is to relieve symptoms and prevent a severe reaction.

Treatment may include:

  • Antihistamines to relieve mild symptoms such as rash and itching

Prevention

There is generally no specific way to prevent an unknown drug allergy. If you have a known drug allergy, avoiding the drug and similar medicine is the best way to prevent an allergic reaction.

Steps you can take to protect yourself include the following:

  • If you have a drug allergy, always Inform your health care workers. Be sure that your drug allergy is clearly pointed out in your medical records.
