I have now resumed sinus mode after a 36 hour episode. Thank you everybody for advice and encouragement.
The GP has just started me on iron pills (Ferrous Fumarate 210 mg) for iron deficiency. I took the second tablet this morning and (as an overthinker) I realised my episode of AF coincided with taking my first iron table.
As It was my first episode for nearly three years, so I thought I would explore if it was a 'coincidence'.
And an internet sites did state that this was possibility that iron tablets could cause problems with people who have AF. I did ask the doctor if there were any interactions with drugs already being taken but she said there were none.
Naturally I hope it is just a coincidence but has anyone any experience of this possible issue?
