Which of the following is a contraindication for prescribing to a patient on warfarin?

Metronidazole
Ibuprofen
Acetaminophen
Erythromycin

The correct answer is: Metronidazole

Acetaminophen, Ibuprofen, and Erythromycin are all medications that can potentially interact with warfarin and increase the risk of bleeding. This is because they can inhibit the activity of the enzyme responsible for breaking down warfarin in the body. However, while these interactions can be managed by adjusting the warfarin dose, Metronidazole is a medication that should not be prescribed to patients on warfarin due to its potential to significantly increase the risk of bleeding. It is important for healthcare providers to carefully review a patient's medication list and consider potential drug interactions before prescribing any new medication.
