looks like I am switching to T3. currently taking NDT

I have been taking nature thyroid for some time now and have found a perfect dosing regime. ie 1.25 grains twice daily and a nibble most days if my head starts swimming. Due to the unavailability of NDT I am ordering some T3, 25mcg ,100 tabs. I have some levo lying around but not sure whether to take straight T3 or mix with levo and how much I will need either way.

My nature thyroid is 22.5 T3 daily with nibbles to about 25 mcg in all and 95mcg of T4 plus nibbles.

So I think in all I am taking 100 mcg of T4 plus 25mcg of T3. Does this sound like a good dose if I mix.

How would I take if I just took T3. Could I just take little nibbles through out the day. I think I will need to at least split dose as daily dose of NDT taken all at once makes my heart thump.

Mandyjane,

Do you have TSH, FT4 and FT3 from taking 2.5 grains NDT?

You should be able to quarter a 25mcg T3 tablet with a pillcutter to divide dose but I doubt you'll be able to cut it down into smaller doses.

I would start with T4 + T3 rather than switch to T3 only.

I only has a recent TSh result of 0.49. I have not bothered to get blood done in recent months as my body is very clearly dicating need. I cant stand up if too low and heart thumps if too much with about half a grains leeway in between. I am starting to feel weird now as due a dose. I am very nervous about changing. A year ago and low thyroid hormones meant fatigue and constipation and weight gain. Now a low dose effects my brain very quickly and I am sure I have permanent brain damaged from the time I stopped the hormones the end of last year. I am concerned that messing about could lead to a coma and still normal blood results.My GP has said if blood indicated thyroid problems and I get ill due to change or lack of medication he will prescribe T3.

Mandyjane,

Impossible to tell whether you are optimally dosed with only TSH to go on so I think you'll have to suck it and see how you do on 100mcg T4 and 25mcg T3.

I have no thyroid and was off meds for 4 weeks. I wasn't at all well but I was still walking about, feeding myself and my dogs. I was nowhere near going into a coma.

Thanks clutter. I dont think I would be walking about for 2 days or even one now with out thyroid hormones. Something funny has happened to me.

I will check my T4 supply to make sure in date and wait arrival of T3.
