A patient taking oral contraceptives has diabetes. When prescribing antibiotics for dental treatment, what is the risk?
Show answer and explanation
Correct answer: A. Antibiotic increases blood glucose
- A. Correct. Antibiotics can disrupt gut flora responsible for enterohepatic recirculation of estrogen metabolites, potentially reducing OCP effectiveness. Patients should use backup contraception.
- B. Incorrect. Analgesics do not interfere with oral contraceptive hormone cycles.
- C. Incorrect. Dental antibiotics do not cause significant hypoglycemia in diabetic patients (some fluoroquinolones can affect glucose, but this is not the primary dental concern).
- D. Incorrect. Antibiotics do not significantly raise blood glucose in diabetic dental patients.
