Hyper, bloods results, what happens now?

Hello all

Recently diagnosed Hyper (Graves) 6 weeks ago.

TSH <0.01

T4 51

After 3 weeks on Carbi (40mg) T4 went down to 42

Another 2-3 weeks later (today!) on a reduced Carbi dose (20mg) T4 is 20! Within range.

TSH is still dead.


Its only been 5 weeks, has this happened fast???? My Endo (who I haven't seen yet) told me I would take months to get back into range with such a high T4. She said at least 4-6 months for most....

My doc says to stay on 20mg for another 4 weeks and review? Really?? I understand I need to get lower for TSH to kick in (hopefully)... But since I have bad rashes and hives, I would've thought reducing a little wouldn't hurt now?

Any advice GREATLY appreciated :-)

  • Wildpoppy,

    You seem to have responded quickly to Carbimazole but FT4 is high in range and very likely to rise if you reduce dose too quickly.

    It can take months for TSH to recover and some hyperthyroid patients find TSH never recovers. Most hyperthyroid patients are prescribed Carbimazole for 9-18 months to regulate thyroid before weaning off and trying for remission.
