Is it OK if I take warfarin (or other oral anticoagulants ) with alli?
No. Do not take alli with this medicine. Warfarin (or other oral anticoagulants) are used to thin the blood. You must not take alli if you are taking warfarin or other blood thinning medicines since your blood clotting function (INR; international normalised ratio) test result could change. If you have any further questions about this, please check with your doctor.
