Thank you to everyone who replied to my post about this. Really a great help and advice.
I spoke with the GP pharmacist today and she was very helpful and understanding and is going to ensure that the brand names are on my prescription. There was no argument at all or any problem moving from generic to the brands I have been on up to now. She is even going to issue a new Flecanaide prescription for the Mylan one which I can exchange for the generic one I was given.
I know it was certainly helpful in the conversation that I could mention I was part of this group and the AFib Association, and had gained some of your feedback and experience, so I came across as knowledgeable!!
Thank you all very much again x
