Are you, by any chance, located in U.K?
We can't assume that just because the gp changed her dose that she was over medicated. All too often, doctors look only at TSH, which is not a thyroid hormone and does not correlate with symptoms. Tremors and feeling faint could be symptoms of over medication, as could the tiredness. Weight gain is, typically a symptom of under medication and of course, so is tiredness.
My own TSH has been very low (< 0.01) for over 6 years and I've never been over medicated.
Will look forward to seeing your daughter's actual test results with reference ranges.
It takes 4-6 weeks for a dosage change to stabilize, but she could start seeing subtle differences in the way she feels much sooner than that. The tiredness will probably be the last thing to resolve.
You might have them test her vitamin B-12 level to make sure it's high enough to sustain her. Vitamin B-12 that's too low in the range can cause extreme tiredness. Supplementing can help immensely.
Thank you. I will try to get actual test results from daughter. The uni GP changed her dose today back to 75mcgm per day so I assume she must have been over treated. I assume that even if this is successful in stabilising her, it will be a while before effects are felt... she may have to cope with hyper symptoms during her exams,.
Please post the actual test results, with reference ranges. Low TSH doesn't necessarily mean your daughter is over medicated, but if she has symptoms of being hyper, she possibly is.
We'll be able to tell more once we see the results.
