I’m new to this site, but was diagnosed & had RAI in 1994. I take .137 Levoxyl now at age 55, but at age 40 it was .112 and my current doc says it is likely a normal response to menopause.
One thing that can cause levels to change is a change in brand of hormone. Over the years I experimented with more affordable brands and found that my levels were different with each brand. I will never change brands again. A pharmacy tech at Walgreen in Dothan, Alabama told me last spring that, "Levothyroxine is the very same identical thing as Levoxyl, and your insistence that we give you the other brand is ridiculous." After three months on Levothyroxine I was extremely ill and went online to research my symptoms…and thank God I found this website. I’m back on the regular stuff and if I’m lucky, I may even sweat before the summer is over!
I also have found that some docs interpret the test results strangely. At one clinic the doc insisted that I must have TSH readings in the upper end of the scale to avoid osteoporosis. At the same clinic another doc looked at the "therapeutic" range and decided that I must be exactly in the center of the range. Depending upon who was working the day of my appointment, I was on .112 for a few months, then .150 the next time. Being uninsured and unemployed is a medical adventure…
