What tests can we do to check effect of dabigatran on patient with heart problems, multi infarct stroke dementia? Recently moved to d'tran from warfarin after stroke. Any interaction with antideprests

Yes but not readily. There is a test that measures dagtriban but not readily available. You can see if someone is toxic by looking at inr and if >1 than dose maybe high.
No tests. Available and no drug interactions with antidepressant meds.
