Synthroid increases and how it can have adverse effects?

[Thendry1963]

I am 52 yr old female, menopausal, with a thyroid condition. I have been the asking Synthroid for over 20 years starting out with the lowest possible dose, I had my bloodwork done 8 mets go and my dr increased my Synthroid at that time. Not thinking anything of the increase I have been increasingly having problems with anxiety, nausea, hot and cold flashes, just feeling horrible. Went back to the dr and he suggested antidepressants to which after two failed attempts because the drug made me feel incredibly worse I am finally having bloodwork done tomorrow for my thyroid. My question is would having such a small increase of my last bloodwork give me all theses symptoms? I'm feeling extremely emotional and need to feel normal. Please tell me what type of bloodwork I should ask for?

What were your meds increased from and to?

You should make sure your doctor test FREE T3 and FREE T4.  Be sure FREE is specified for both tests, otherwise you will get total T3 and total T4, which are not nearly as useful.  TSH should probably be tested also.  

Do you know what your doctor based your increase on?  Were you having hypo symptoms?

You say your last blood work was 8 months ago.  When did you start feeling your current symptoms?
