Drug Allergies

Allergic reactions to drugs or medications.

Common Types of Drug Allergy

A person can have a drug allergy to any drug but the following are the most common types of drug allergies.

  • Penicillin
  • Insulin
  • Contrast Dyes
  • Anticonvulsants

Symptoms and Diagnosis

  • skin rashes
  • hives
  • swelling of lips and tongue
  • wheezing
  • anaphylaxis (severe allergic reaction)

Allergy skin testing or challenge testing by an allergist or medical professional can be performed to diagnose a drug allergy.

Prevention and Treatment

Avoidance is the best possible treatment for a drug allergy. For some forms of drug allergy there may be allergy skin testing available and that determination will be made by an allergist.

People with severe drug allergies should carry epinephrine (know as an EpiPen) at all times and should consider wearing a medic-alert bracelet.

For severe allergic reactions, seek emergency medical attention.
