...has used Warfarin for many years. ... {The expert} advised that there is a much better product available that he uses. This is called Plavix. He suggested that my boss should ask his GP to look into Plavix to see if it will be suitable for him. Anyone using Warfarin might want to do the same
Errr..?
I believe Plavix is an alternative to Asprin, acting similarly against platelet clump formation, and therefore not really an alternative to Warfarin, which acts rather differently.
Anyone on Warfarin that suffers a severe nosebleed really should get their INR (clotting/bleeding propensity) checked fairly urgently... (there are more serious potential sites of bleeding...) And I would have expected anyone that had been on Warfarin for "several years" to be well aware of that.
