Blood Thinners (Anticoagulants-Coumadin, Plavix etc.)

Cardiovascular Medications

My doctor has started me on Warfarin (Coumadin). How will this affect my diving?
A diver who has been prescribed an anticoagulant, e.g., Coumadin® or Warfarin®, should be warned of the potential for bleeding: excessive bleeding can occur from even a seemingly benign ear or sinus barotrauma. There is a potential risk that, if decompression illness occurs, it may then cause significant bleeding in the brain or spinal cord. The diver must be able to equalize without difficulty. Also dive physicians would recommend conservative dive profiles to help further reduce the risk of DCI.
