Hi all, started: 210mg ferrous fumarate once a day for low ferritin which is at 15. noticed ridiculous amounts of anxitey and panic attacks 6 days later! Had none of these symptoms before the tablets, only what i would class as normal anxitey. Has anyone else experienced this? Doctor told me to come of them for now, 2 days I haven’t taken them still feeling pretty dreadful. Not sure how long the side effects will take to subside.
