Which statement about prescribing antibiotics is NOT true?

Correct answer: D. Antibiotics interfere with the analgesic effect of NSAIDs and acetaminophen

• A. This IS true and is the most important principle: drainage and removal of the source (pulpectomy, incision and drainage, extraction) is definitive treatment; antibiotics are adjunctive.
• B. This IS true (with nuance). Rifampin is the only antibiotic with well-proven reduction of contraceptive efficacy, but the current standard of care is still to advise patients on any antibiotic to use an additional method of contraception for the cycle.
• C. This IS true. Antimicrobial stewardship is a core professional obligation; dentists write a meaningful share of all outpatient antibiotic prescriptions.
• D. CORRECT — this is NOT true. Antibiotics do NOT interfere with the analgesic action of NSAIDs or acetaminophen. These act by entirely separate mechanisms (COX inhibition versus bacterial cell wall, protein, or nucleic acid synthesis). Pain from an odontogenic infection improves as the infection resolves, but that is not a pharmacologic interaction with the analgesic.

Note: Antibiotics are indicated for systemic involvement — fever, malaise, lymphadenopathy, trismus, spreading swelling, or immunocompromise — not for a localized abscess you can drain.
