If you take prescription blood thinners, never stop suddenly. ALWAYS check with your doctor. If you see a conventional doctor you may want to try a seasoned holistic doctor to help you get off of prescription medications. You MUST do this in an educated way with an educated practitioner. You are talking life or death here!
Also don't take nattokinase if you are taking blood thinners without a doctor's OK.
