Hyperthyroidism Support Group

Hi and welcome:

That's good your doctor puts you on MMI (Methimazole) three times a day. That should be every eight hours for you.

Be sure to get your Free T3, Free T4, and TSH tested every six weeks, at least. You want to keep these at mid ranges. Then work with your doctor to slowly reduce the MMI all the while staying at mid ranges.

It will take at least six to eight weeks to use up the extra stores of Iodine before your Free Ts start dropping.

Are you on any beta blockers to lower the heart rate and any hypER issues?

Thanks for the reply. I am not on anything else currently. My doc wants to wait and see what happens in the next 6 weeks. What should I expect in the way of side effects while on MMI?

Oh and btw, I am experiencing dizziness. Is this a reaction from MMI or is this just another by-blow of the hyperthyroidism?

I remembered dizziness when quite hypER. I didn't really see this on the MMI side effects list and don't recall it as that for myself from using the MMI.

I don't think you are on too high of a dosage (15 mg per day) to have too much side effects going on. It happens more at 40 mg and above. But there's always that rare chance of it happening for anybody.

I experienced mild dizziness in the past 2 weeks. This dizziness was markedly more pronounced. Maybe just my condition progressing?

Thanks for the hug!

Ask for labs at four weeks from starting MMI to see if you are on track with things instead of waiting six weeks. Get the Free T3, Free T4, and TSH done.

But if you do experience worsening of the dizziness and/or other symptoms, give your doctor a call.

Hi:

For the bottom ones of the thyroid labs would you please include the ranges? The ranges will be on the right side of the paper and are different from other states and countries.

Were these labs done before you were put on the MMI?

I'll come back soon to comment.

{{{hugs}}} :-)

Sorry, I'm really a newbie at this:
TSH *0.06 uIU/mL [0.34-5.66]
FREE THYROXINE, 1.14 ng/dL [0.52-1.21]
FREETRIIODOTHYRONINE *4.09 pg/mL [2.20-3.80]

Hi! Your tsh is low but that is the way Graves is, the tsh stays suppressed, sometimes for years, by the antibodies. You have a very mild case. Your FT4 isn't even elevated, just your FT3. You will go hypo quickly if you aren't monitored by the month. You should be getting a dose reduction by the end of the month, your FT4 will have dipped too much on the meds and you will become hypo.( not a good thing either, although docs think safer, but feels like crap) make sure you aren't being dosed by tsh but by the "free" levels. The dizzyness came when I was put on too high a dose,(only 5 mgs for me) it went away but my levels dropped too much on this dose. I had a mild case too.
