I have been on Thyroid S for a tear now, gradually rising to 2.5 grains. All appears well except for the fact that the last twice I have had a virus, I have had tachycardia with it.
My usual GP was not bothered by this, but I saw one if his colleagues last week who picked up that my thyroid had not been checked for nearly eighteen months and ordered a TFT.
Without thinking, I got it done the same morning, four hours after I had taken one grain of Thyroid S. The results came back as:
TSH <0.02 (0.27-4.2)
FT4 27 (9-26)
I managed to persuade him that the suppressed TSH was not significant, but of course the FT4 was over range so he has asked me to reduce my dose. He thinks I'm still on Levo, so he said drop from 125 to 100.
I suspect that if I had taken no meds since the previous morning, as would normally be the case for a blood test, my FT4 would have come back well within range, so I'm kicking myself now.
The tachycardia has disappeared with the virus, but the GP will now congratulate himself on being right that it was my thyroid. I have no signs of over-replacement now. I really need to speak to him about whether I am always going to get tachycardia now with a virus, what I should do about it when it happens etc, but I seem to have shut that door.
I swapped to Thyroid S to regain control of my situation because I could not get enough Levo off the GP or more than 28 days' supply at a time.
