Warfarin is an anticoagulant that requires careful monitoring of a patient's international normalized ratio (INR) levels to avoid adverse effects such as bleeding complications. Documentation must include not only the standard 'Five Rights' but also pertinent laboratory values, such as the most recent INR, which guides warfarin dosing. Documenting the patient’s diet and concurrent medications is also good practice as they can affect INR levels and warfarin efficacy, but the INR is the most crucial piece of information specific to warfarin administration. The manufacturer and physical description of the pill are not commonly required pieces of data unless there is a specific concern that necessitates their inclusion.
