Does eating licorice candy interfere with any prescription drugs?
A. Licorice can raise blood pressure and increase potassium loss, so it may interfere with the effectiveness of many blood pressure medications. People taking Lanoxin (digoxin) or Coumadin (warfarin) should probably avoid licorice. Prednisone or diuretics that deplete potassium are also problematic. When in doubt about interactions, check with your pharmacist.
