Iron infusion & over symptoms

Incoguto profile image
5 Replies

Hey all,I was wondering if anyone experienced thyroid overmedication symptoms after iron IV?

It's day 3 today, I have much better energy, but also feel jittery and hot at times.

I assume iron is making the cellular absorption better and increases conversion.

I'll probably do another ft4 ft3 test soon just to compare. I have read that ferritin peaks 7-9 days after infusion, so probably would be wise to keep the same dose for now?

Thank you!

Depending on how much iron was infused etc. it can take quite a few weeks if not months to truly settle blood work wise. I had a ferritin test run I think 6 weeks after my infusion and my ferritin was still sky high.

Don't change anything based on side effects from an iron infusion. It may be a passing phase anyway as your body gets used to better iron stores.

Retest thyroid after 6-8 weeks if you think your levels might have changed.

Thank you!

I had 500 of Monover, my hematologist said I might need it every 3 months, but we will need to check bloods closer to the time. There was another woman there who needs them every 6 months.

Wow, maybe it will last longer for me, do you remember what your ferritin was at 6 weeks? I was told ferritin will peak after a week and will be way over range.

It's now day 3, still getting some light side effects, currently back pain.

Have you felt better after infusion?

My ferritin was at 611 after 5 weeks and then a further month after that 239 so it does take quite a while for it to find its own level.

I felt slightly better but its since transpired that I have other deficiencies that I'm only just beginning to treat.

I’m in the research phase of iron infusions, thanks for your post. If you think to come back and update on how it’s going, please do!

No worries at all,you can have a look at my newest post. I don't regret getting the infusion, but I had the anaphylactic shock shortly after starting it. The hydrocortisone injection helped as I couldn't breathe and my chest got tight. The nurse was great and prompt.

My levels yoyo'd after, I felt great next day and then overdosed, checked my levels this morning, my ft3 went up by 20% (in 4 days!). It could be a coincidence, not sure, but I'm slightly lowering my dose, I ended in ED with tachycardia and tremors on Wednesday. Again this could be a mix of steroids, iron IV and thyroid meds.

I hope this somehow helps! Iron infusion is helpful, but there could be side effects. No one told me what to expect from it so it was a bit of a shock.
