A 50-year-old female patient on estradiol (hormone therapy) is undergoing a dental extraction. Regarding antibiotic use in this patient, which statement is INCORRECT?

Correct answer: A. Antibiotics can hinder the effect of analgesics

• A. Correct — this is the INCORRECT statement. Antibiotics do NOT hinder the effect of analgesics. They have no meaningful interaction with common analgesics like ibuprofen or acetaminophen. Analgesic efficacy is unaffected by antibiotic administration.
• B. Antibiotics can and do cause GI disturbances (nausea, diarrhea, Clostridium difficile overgrowth) — this is true.
• C. Some antibiotics (rifampin, broad-spectrum antibiotics) can reduce the efficacy of oral contraceptives — this is a recognized drug interaction.
• D. Antibiotics can cause allergic reactions ranging from rash to anaphylaxis — this is true.
