Description

Order a penicillin g allergy IgE blood test to detect an allergy to penicillin g. This test measures the amount of allergen-specific antibodies in a blood sample. 

Penicillin G, also known as benzathine, can be used to treat a large variety of serious bacterial infections, including meningitis, pneumonia, anthrax, syphilis, and gonorrhea. This medicine is a long-acting penicillin antibiotic that prevents the growth of bacteria.

Side effects of a penicillin g injection may include:

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

An allergy to penicillin g triggers a reaction in an individual's immune system. The body views certain substances as toxic and produces IgE antibodies to these contaminants. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction.

Allergy symptoms vary from one individual to the next ranging from mild to severe reactions, which can be experienced within minutes to a few hours after exposure. Common symptoms of a penicillin g allergy may include one or more of the following symptoms:

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

It is easy to see how close the side effects are to allergic reactions. It is crucial to know for sure if an individual has a penicillin g allergy or they merely experienced common side effects.

If an individual does have an allergy to penicillin g, it is advised to avoid all drugs in the immediate penicillin family, including:

  • Ampicillin
  • Amoxicillin
  • Nafcillin
  • Amoxicillin-clavulanate
  • Piperacillin-tazobactam
  • Dicloxacillin
