Question

Within two hours of taking the first dose of amoxicillin, the patient developes shortness of breath, a rash over the majority of her body, and swelling of the lips and tongue. What is the patient most likely experiencing?

A) A side effect
B) An allergic reaction
C) This is a normal response to amoxicillin
D) A teratogenic effect

Answer 1

The patient is most likely having an allergic reaction to amoxicillin. The symptoms like rash, and swelling suggest anaphylaxis, a severe and life-threatening condition that requires immediate medical attention.

Step-by-step explanation:

The patient is most likely experiencing B) An allergic reaction to amoxicillin. The symptoms described, including shortness of breath, a rash, swelling of the lips and tongue, can potentially lead to a life-threatening condition known as anaphylaxis. This severe immune response triggers a mass release of histamines, leading to symptoms like the ones observed in the patient. It is crucial for someone experiencing such symptoms after taking a medication to seek emergency medical treatment immediately. If the patient had a known allergy to penicillin and related antibiotics, they may carry an epinephrine autoinjector (EpiPen®) which can temporarily control the reaction until medical help is received.
