Just thought you might like to know the following.
Because I am having a small surgical procedure tomorrow (no Flapjack its not the unkindest cut of all ) I had to have an extra INR test on Tuesday to make sure it ws between 2 and 3 as required. Panic it was 5.2!!!! I had fogotten that some drugs affect INR quiet a lot and should have checked earlier having started propafanone about two weeks ago. Lovely lady agreed she would see me first thing today for a second check and by not taking my warfarin Tuesday and Wednesday evenings my INR this morning was 2.7 so all OK. Phew!! Thought it may be useful for people to see how quickly it can change. and remind people that if you alter your drug regime in any way you need to have extra checks.
