People taking blood thinners will obviously bleed more. Nose bleeds (epistaxis, as it is called by doctors) are one of the most common complaints, and can be serious in some people. The first thing to do is to speak about your problem to the physician who is managing your coumadin level. Most people check their INR regularly (INR is a measure of how thin your blood is), and if your blood is too thin at these visits, that can predispose you to regular bleeding
. Coumadin is a tricky drug to regulate, as it is affected by so many other medications and dietary aspects. More or less of just a small thing can be just enough to completely alter the efficacy of coumadin.
Additionally, night time is a common time for minor trauma to the nose. Whether you rub it, bump it, blow it, or anything else, many nose bleeds happen in the middle of the night. The front part of the nose has many small vessels that are susceptible to repeated trauma, and once you have one nose bleed, you are more likely to have another. Please speak with your doctor
to make sure your blood is not too thin, and to see if there is something that needs to be done about your recurrent bleeds.
