Question regarding RAI

by Andi313, Sep 03, 2007 11:33AM
Hi everyone,

I am new to the board. I am 43 years old and was referred to an endo in March of this year by my primary due to mild hyperactive thryroid. I was diagnosed with perimenopause and believed the hot flashes and sweating was due to that condition vs. the thyroid. I also had difficutly sleeping.

Boy was I wrong. When I went back to get my levels rechecked (3mos), my endo advised that my levels were not even on the chart. He recommended RAI (done 7/9/07) to get it under control quicker and I agreed. Unfortunately, I have had adverse reactions to beta blockers he and my primary have put me on for symptom relief and to protect my heart (never had racing heart) and went off the last one 5 days ago.

My primary checked my levels again last week and I am still hyperactive. He will explain in detail at next weeks visit. Does anyone know when I can expect to go underactive or when I will even know if the RAI will work? I am concerned about possible heart issues from being overactive.

It may take more time for the RAI to work -- sometimes up to 6 months, the average is about 6-12 weeks.  There are many types of beta-blockers but I imagine your doctors have already tried a variety of them to see if the side-effects can be avoided.

I am back on Coreg (3rd beta blocker with least side effects for me) due to extreme symptoms. I got my labs and my T4 is normal range, T3 almost normal and TSH .03 (worse then before RAI). I am assuming this is happening due to the RAI?

My primary has advised that TSH is the last to come into alignment and I should not get discouraged that the RAI did not work yet.

My endo has indicated the shortness of breath I am experiencing may be the thryoid vs the Coreg. I had my labs taken again last week and see my endo tomorrow to discuss. I am anxious to go off the beta blocker and start feeling better.

Thank you for your response.
