What allergy is indicated by red spots on the arm?

• A. Ibuprofen allergy
• B. Penicillin allergy
• C. Latex allergy
• D. Antibiotic allergy

Answer: (B)

The presence of red spots on the arm can indicate an allergic reaction, and in this context, a penicillin allergy is particularly relevant. Penicillin, a commonly prescribed antibiotic, is known to cause various allergic responses, including skin reactions such as rashes and red spots. These reactions are typically due to the immune system's response to the penicillin molecule, which it mistakenly identifies as a harmful substance. In cases of penicillin allergy, red spots or rashes may appear shortly after exposure to the drug, reflecting the body's immediate hypersensitivity response. Such skin manifestations are significant indicators of an allergy and can range from mild to severe. While other allergies, such as those to ibuprofen or latex, may also cause skin reactions, they are not typically associated with red spots in the same manner or frequency as penicillin. Antibiotic allergies can encompass a broader range of medications, but if the allergy specifically pertains to penicillin, it aligns most closely with the symptom described in the question.
