About Our Penicilloyl G (Penicillin G/Benzylpenicillin) Allergy Test

Note: Fasting is not required for this test.

This IgE antibody allergy test uses a blood sample to determine if you are allergic to Penicillin G (also known as the antibiotic drug Benzylpenicillin or Penicilloyl G).

Penicillin G is a common antibiotic used to treat bacterial infections such as strep, staph, diphtheria, meningitis, gonorrhea, and syphilis. It is considered a natural penicillin and is typically administered via injection. 

Common side effects of the penicillin injection include:

  • Injection site pain
  • Muscle spasms
  • Mild skin reactions
  • Hives
  • Chills
  • Fever
  • Swelling
  • Joint pain
  • Fatigue
  • Upset stomach

Similarly, symptoms of a penicillin g allergy include:

  • Hives
  • Itching
  • Skin rash
  • Fever
  • Swelling
  • Shortness of breath
  • Wheezing
  • Runny nose
  • Itchy, watery eyes
  • Anaphylaxis

Because of how similar the common side effects are to allergic reactions, it's easy to see why research shows that penicillin allergies are often over-reported. The belief in a penicillin allergy can lead to the use of less-effective and/or more expensive drugs. That's why it's so important to know for certain if you have an allergy to penicillin g or if you've merely experienced common side effects. 

If you do have a penicillin g allergy, it may be best that you avoid all drugs within the immediate penicillin family, including amoxicillin, ampicillin, amoxicillin-clavulanate, dicloxacillin, nafcillin, and piperacillin-tazobactam.

Some of the risk factors that may make you more susceptible to having a penicillin allergy include: 

  • A history of allergies
  • A family history of penicillin allergy
  • Being exposed to high or prolonged doses of penicillin
  • Having an auto-immune infection such as HIV or Epstein-Barr Virus
