ADC Practice Question — Prophylaxis regimens and drug choices

his severe penicillin allergy with anaphylaxis, what…

Pharmacology questions in the ADC written exam test applied prescribing decisions, not rote recall of drug names. This exam-level vignette tests your ability to work through clinical details and arrive at the correct management.

He reports a severe penicillin allergy with previous anaphylaxis to amoxicillin 5 years ago. He takes metformin, lisinopril, and warfarin. His cardiologist has confirmed the need for endocarditis prophylaxis. The dentist is planning the antibiotic regimen and considering surgical antibiotic prophylaxis as well.

B. Doxycycline 100mg orally 60 minutes before procedure
C. Amoxicillin 2g orally since he's on warfarin
