[|AI|]  Hi, Thank you for posting your query. Yes, the most likely cause of coughing small amounts of blood in your cases, could be warfarin-related. Warfarin makes the blood thin, which results in bleeding at times. The reason for your warfarin use in not clear from your description. The dose of warfarin depends on the indication for using warfarin. I feel the dose may have to be reduced for a few days, after which you should recheck the PT, INR; and then adjust the dose of warfarin appropriately. I hope it helps. Please get back if you require any additional information. Best wishes, Chat Doctor. Ly/
