Are there any deaths reported from cephalosporin antibiotics?

Yes.: Severe anaphylactic allergic reactions to cephalosporins (or really any drug, for that matter) have occurred resulting in death.

Possibly: For someone to die from a cephalosporin they must be very allergic to it and not be able to seek medical attention. This is rare. Never seen or heard of a case but the label does list it.

Sure but rare: No drug or procedure or anything we do is without risk but most of the time, the benefit is way better than the risk. Besides anaphylaxis, the cephalosporin group of antimicrobials has been linked to fatal c. Difficile colitis as well as exfoliative dermatitis among others.

Very rare: Very rare anaphylaxis. I'm a doctor 40 years, infectious disease specialist 34 years and never saw a patient die from a reaction to a cephalosporin antibiotic.
