A patient is admitted to the hospital after a severe hypersensitivity reaction to penicillin. Which of the following antibiotics should the patient avoid in the future?

Explanation

• A patient who has had an anaphylaxic reaction to penicillin will also be at risk for a reaction from cephalosporins and carbapenems.

• Penicillins, cephalosporins, and carbapenems all contain a beta-lactam ring in their biochemical makeup. This beta-lactam ring can cause an allergic or even an anaphylaxic reaction.
