<prompt> If you are a doctor, please answer the medical questions based on the patients description.yes I have ccleuk and I have a thrombosis for both I have been taking wayfarin. Now I am very old, my leuk stays steady but I simply have only 1.4 count despite a week of shots of cumadin in the stomach, still it stays low. but I have many skin cancers but now they hurt so much more. how can my count be off so much when I daily take five of warfarin?  <response>: Hello and thanks for your query, The dosage of warfarin varies between individuals. Some people take 2 mg daily and have a therapeutic level of 2 of the INR. A lot of things can affect the level including other medications which you might be taking, body size and diet. Your doctor may need to adjust the dose higher - perhaps to 7.5 mg daily for some time and then reassess the level. Thanks again for the query. Please let me know if I can help you with any additional concerns.
