Preparing for launch
Warfarin Companion
A simple way to capture the details that matter between INR checks and appointments.
Warfarin Companion helps people taking warfarin capture changes, organize what happened between INR checks, prepare for visits, and follow through on next steps. No daily check-ins — just log it when something changes.
Not a dosing tool. It does not recommend doses, interpret INR results, or tell you to start, stop, or change a medication. Your clinician makes those decisions.
