[|Human|] I am on pradaxa - the new blood thinner.  I was diagnosed with erosive gastritis a year ago and spit up bloody sputum every morning when I awake.  It gathers in my mouth when I sleep, and shows only in am.  It seems to be minor.  The pradaxa keeps me from having angina.  I feel that I need to take it.  What should I do?
[|AI|]  Hi, Thanks for asking. Based on your query, my opinion is as follows.1. Bloody sputum usually signifies, problems with oral hygiene.2. Meet a dentist for evaluation of gums, teeth or any ulcers.3. Prada, if it causes gastritis, and bleeding, it would have showed in stools, as dark-colored stools. 4. Presently Prada is not causing any erosive gastritis. Causes of bloody sputum appears to be in mouth. ENT and dentist evaluation will identify cause. Need to look for tumor too. Hope it helps. Any further queries, happy to help again.
