Back in range!

Morning all,

I went back for my blood results yesterday and everything is back in the the mid ranges, except TSH *, and been given a script for Vit D and iron as I'm deficient which could explain why I've been bellow par..

*After my drop in thyroxine my tsh hasn't changed at all from my previous bloods in sept TSH 0.03 ( 0.35-5) has anyone else had this happen, my doctor said it was really strange and that as my T4 had dropped to 14.9 (9-19) from 20.9 I'm no longer over medicated.

has anyone else had this? And any ideas why this could be?

You are only over medicated when the FT3 is over range - so without that result your GP has little to go on. Unless of course you were displaying clinical symptoms of being over medicated. If you put both arms out in front of you with the palms facing down - do the hands shake/tremble ? Often a sign of being over medicated .....

Am sure the VitD will make a difference - how much were you prescribed ? Iron best taken with VitC to aid absorption and prevent constipation....

BeccyD,How much was your thyroxine reduced? That's quite a big drop in FT4. My TSH didn't rise when dose was reduced either.



I was dropped from 125 to 100, and felt awful when it was first dropped and have huge ridges across my nails from the first couple of weeks. Even though I'm still tired and have bad hands and feet I'm feeling a bit better but I'm nowhere near as good as I was beforehand.

I'm prepared to give the vit d and iron ago for a few weeks and see if it make a difference, but if it doesn't I'll go back



BeccyD, ask your GP for 100/125mcg alternate days. That should bring FT4 higher but still within range. FT4, not TSH, should guide dosing.

How low your vitD and iron are, and the doses you have been prescribed, will determine how long you need to supplement before your levels are optimal and you feel improvement. It's likely to take significantly longer than a few weeks. It can take 6-12 months to correct ferritin deficiencies, and if your GP has prescribed 800iu D3 it will take years. Take 500mg-1,000mg vitamin C with each iron tablet to aid absorption and minimise constipation. Iron and vitD should be taken 4 hours away from Levothyroxine.

Low TSH does not mean you are overmedicated. If you feel OK then NEVER reduce your meds. You are a person not a group of numbers.


Ok, I eventually remembered to go and pick up my prescription today, to discover that no iron or Vit D was on it ( doc did my repeat when I saw her). I called the surgery and eventually spoke to my GP who told me that my levels of iron and vitaminD weren't low enough to qualify for it on prescription! I've had a rotten coldy thing for a couple of weeks, so probably misheard her when we were talking about it....or just worse than usual brain fade!

So have bought a multi vitamin with iron and also vitamin D!
