My first doesage (1996 or so) was 100MCG then bumped to 150MCG to get more "in range".
I just got results back, I'm apparently at a TSH level of 0.03 and I'm currently on 150MCG for a total thyroidectomy. Doc want's to cut doseage to 75MCG for 6 weeks.
Is this right?
Could I have been "off" for a long time and not know it?
How can 100 be too low before and now 75 should be good now?
Each laboratory has its own referent values for TSH. What are the referent values for TSH in the laboratory where your TSH was measured?
It is true that TSH-level is the most important parameter for therapy evaluation but for longterm treatment both hormones, TSH and free thyroxine (fT4), should be evaluated. If you had complete thyroidectomy you should take thyroxine substitution for life. Beside TSH and fT4, health condition (presence/absence of symptoms) should be also considered when determining the proper thyroxine dose. You need to take the new dosage of thyroxine at least 8 weeks until you make a new evaluation of the therapy.
You can consult some endocrinologist about this.
I'm not sure what their reference is but I remember starting at 100MCG but I still felt "off". I was on one side of "their" range so I asked to be bumped to 125MCG to see if I improved. I felt much better.
The only reason I was on 150MCG is because the mfg changed and they had a lower potency.
I just picked up my 100MCG prescription last night. Let's see what happens.
