In May 2010, my family doctor sent me to an endocrinologist after blood tests showed decreasing TSH and I had had some symptoms of hyperthyroidism for several months prior. The endocrinologist found a nodule, and did a scan which indicated it was hot. He also ran the antibodies test for Graves which came back negative.
Listed below are my lab results (2 different labs) and medications:
LAB RANGE: TSH 0.34 – 4.82 mU / L
Mar 6.10 TSH - .01
LAB RANGE: TSH 0.38 – 5.5 mU / L T4 – 10.5 – 20.0 pmol / L
Mar 15.10 TSH - <.06; T4 – 21.6
10mg Methimazole; 80 mg Propranolol
Jul 5.10 TSH – 4; T4 - 13.9
Sep 6.10 TSH 7.2; T4 - 15.69
5 mg Methimazole ; 80 mg Propranolol
Feb 4.11 TSH 2.5; T4 - 15.3
5 mg Methimazole; 40 mg Propranolol
May 14.11 TSH – 1.7, T4 not tested
I have now been taken off the Methimazole, and am weaning off the Propranolol (I see the cardiologist in Nov) and wanted to know what the likelihood is that the medication will have permanently prevented the nodule from becoming active again and if there is a time frame - i.e.: if my symptoms don’t return for 3 months, can I be reasonably assured the problem is solved permanently? Thank you for your assistance.
