I have a medical condition called atrial fibrillation, where the heart has an irregular beat. This may lead to the formation of clots and increase the risk of strokes. Normally it is treated with blood thinning medications. I have taken warafin for many years. Although effective it is a somewhat dangerous drug. It has many interactions with other medications and it is also necessary to have regular INR tests to check for the level in the blood. Monitoring is necessary to ensure the blood thinning is neither too high nor too low. Both can lead to serious situations.
A new drug called apixapan is now available. Tests have shown it to be as effective as warfarin, has few side effects, and is safer. However the main advantage is that INR testing is no longer necessary.
When I was in Australia my cardiologist, David Colquhon, changed my medication from warfarin to apixaban. It is great to be off warfarin.
