Need Help Regarding TSI/Hypo -

October 1, 2003

Hi Barb,

I had labs done 60 days after adding the Synthroid, though I could have come in

earlier if symptoms warranted it. Apparently it takes at least four weeks for

labs to reflect the Synthroid.

I haven't heard of Synthroid raising TSI, but just the opposite (some people

suspect the natural hormone, Armour, of this). I've never had TSI done and am

about to argue for it tomorrow as my endo announced at the last visit it was

time to start lowering my PTU (about 1 year since starting it).

In my case I simply added the Synthroid and didn't have to change my PTU dose.

Someone here may have advice about the sequence for raising your Tap and adding

the Synthroid. I'm not sure if you'd want to do both at once or do one first.

But in any case, despite what 's doctor wrote the combination seems to

have worked well to keep me from getting hypo while taking a fairly large dose

of ATD. I did feel a rise in energy and alertness and also lost a little weight

shortly after I started the Synthroid (which made me worry I was getting hyper

again) but things soon stabilized and the labs 60 days later matched my

pre-Graves' labs.

best wishes.

Hi -

Thank you so much for this. I really do need to hear

this right now. I was going to start the Synthroid

today, but I'm finding I'm really scared of either

raising my TSI as a result, or becoming hyper quickly,

or whatever. I think I will have my T's and TSH done

again tomorrow - it will have been three more weeks as

I've been going. It may help me make up my mind, if I

have gone further hypo.

Then I can go ahead and start on Friday, if I have my

labs back tomorrow afternoon. I see my endo Friday

anyway.

Have you been monitoring your TSI by chance? I'm

wondering if mine will go higher still if I add the

T4. It sounds like if I'm starting with 25 mcg. of

synthroid, I should be on 5 mg. of Tap anyway. I

think someone on mediboard confirmed these doses as

well. So I will increase my Tap to 5 mg. How often

were you having your labs done after starting the

Synthroid?
