I was on Armour (5 grains or 300 mg), and I was not sure how to interpret my labs, so I asked to be switched to Erfa...but now, I am feeling more and more hyper, I am itching all over, and I just cannot seem to find the right dosage for me...on Armour, I felt OK, but did not think my labs were optimal. These are my labs on 5 grains of Armor, and I'd appreciate if anyone knowledgeable would comment on them:
FT4 1.1 (ref 0.7-1.5)
FT3 2.9 (ref 1.7-3.7)
TSH completely suppressed (<0.001), but I know you should not care about that when on NDT.
Both anti-TPO and anti-thyroglobulin were within range, for the first time in 15 years (I was diagnosed with Hashimoto's in 1999, and my anti-TPO levels were +6000; now they were <6 (ref <6; anti-thyroglobulin <4; ref <4).
On 5.5 grains of Erfa (+/- the equivalent of 5 grains of Armour), my labs were:
FT4 1.2 (0.7-1.5)
FT3 3.6 (1.7-3.7)
So, instinctively, I'd say my levels look better on Erfa...however, I have several hyper symptoms: losing a lot of hair, insomnia, excessive sweating, rapid heartbeat, terrible itching...most nights, I wake up drenched in sweat.
I'd really appreciate if anyone who has found an optimal dosage of NDT would tell me what symptoms to look out for, what levels to aim for, and how to tell if you are hyper, hypo, or optimally treated...
I am in Belgium, where only Erfa and Armour are currently available, so other brands would unfortunately not be an option at the moment.
