TSH after RAI

[Smilerdeb]

Hi
I had RAI nearly 14 weeks ago and have been put on Thyoxin (Eutroxsig) and doses have been 'upped slowly' to 75mcg 3 weeks ago.
My TSH has risen in the last 2 weeks to 2.26 (previously 1.45 and on 66.5mcg). I would've expected that with the dose being bumped up that my TSH wouldve gone down but it hasnt.
My FT3 and FT4 are within normal reference range.
Can you tell me why my TSH and my FT3 & FT4 has risen when my TSH shouldve gone down.
My levels for the last 2 weeks are as follows:

11TH SEPT 2008
FT4 17.7 (10.0-19.0)
TSH 1.45 ( 0.50-4.00)
FT3 4.7 (3.5-6.5)

25TH SEPT 2008
FT4 19.0 (10.0-19.0)
TSH 2.26 ( 0.50-4.00)
FT3 4.8  (3.5-6.5)

I felt better when my TSH was under 2.0 but my Doctor has told me NOT to increase my Thyroxin.
Any information would help.
I am a 49 year old woman who had early menopause 7 years ago.
Thankyou

I have had tests done showing conversion problems and am very drug sensitive that the T4 has been dropped down as I had hyper symptoms as well as hypo symptoms.
I know I will never get to the 150mcg Eutroxsig as even the 75mcg dose had to be dropped back to 62.5mcg due to levels borderline hyper and symptoms showing the same.
They dont have Armour here in Australia so T3 is going to be prescribed but I am waiting a few weeks to see how the 62.5mcg dose goes. At present, I am having hyper and hypo symptoms.
If the T3 sends me hyper then I will try another med.
I am pretty pro-active in my symptoms and see my Doctor on a regular basis and have from the time of diagnosis of Graves, Hyperthyroidism, RAI, Thyca and Keyhole TT.

Thankyou

Also, don't go by the test numbers itself. may be your body needs high T4 at the top, to bring down T4 may put you in the hypo range. test range is an average for all people. your own body's feeling is the best way to determine what test results you should have.  Good luck to you.

How do you know you have T4 to T3 conversion problem ??  Your test results looks OK. Both numbers are in the normal range even T4 is at the top. these tests change a little from time to time and varys depends on the person..  My suggestion is try to stay with T4 only if you can. T3 is hard to control, don't take T3 unless you really have to.  RAI usually take 6 months to get the full effect, by that time you should take 100-150 mcg of meds.  If after 6 months your test results are not normal or you have any hypo or hyper symptoms, then adjust your meds that time. Reduce T4 for T3 now is a little too early.

Hi Smilerdeb . Just wanted to stop by and say hello.  C~

[Smilerdeb]

Thankyou very much for your precious valuable time in this subject.
I have since been advised to stop the Thyroxin for 3 days to bring down the level of FT4 a little to stop me going Hyper and been told to resume back on 62.5mcg Thyroxin.
My Doctor advised me that should I decrease the dose , it would take a lot longer for the levels to drop so has advised I stop the Thyroxin for 3 days instead.
Once again, thankyou for your valuable time.

Your T3 levels are normal -- there appears to be adequate conversion.  Would give it some more time as it has only been 14 weeks and there may be some "leveling-out" still after the RAI.   Usual full replacement is 100-150mcg depending on weight, age, etc.  The target TSH is 0.3-2.5 -- close monitoring the first 6 months after RAI for hyperthyroidism is important.

[Smilerdeb]

I have since discovered that I have a conversion problem from T4 to T3 and have lowered the thyroxin back down to 62.5mcg and if within 3 weeks, the FT3 doesnt come up....will drop the dosage of Thyroxin down to 50mcg and add some T3.
As you know...Armour is not available in Australia so will be taking a T3 med with my Doctors approval.
I am SUPER DRUG sensitive so of course, this is being monitored by myself and My Doctor.
We work very well together and have a good relationship as Doctor/Patient.
Any comments you may have would be most welcome.

Sorry I forgot to mention I hadHyperthyroidism and Graves Disease prior to RAI with fibrillations resulting in Hyper condition being dangerous.
