An INR may also be collected when starting, discontinuing, or changing doses of medications known to interact with warfarin.

Ongoing alcohol use is a concern for the risk of gastrointestinal bleeding, which will complicate anticoagulation management. In the event of toxicity, physicians must rapidly assess bleeding risk or the degree of bleeding and identify less common complications of warfarin therapy. Coordination with a pharmacist, blood bank technician, and nursing staff are often required to quickly obtain and administer appropriate reversal agents and appropriately monitor response to therapy.

Never assume anything about a patient without doing further investigations. Managing drug-drug interactions related to warfarin and its sequelae should involve an interprofessional approach involving laboratory technicians, nurses, pharmacists, and physicians.

The INR was 2 a week later, but one month postdischarge it was supratherapeutic (3.4). Given the potential interaction of warfarin with the antibiotics, INR was rechecked two months postdischarge and found to be 5.5.
