This assures sufficient T3 levels
and thyroid effects in the body. Since NDT has more T3 than the human
thyroid gland produces, the well- replaced patient’s FT4 will be below the middle of its range, and the FT3 will be high “normal” or slightly high before the next AM dose.
Excessive thyroid dosing causes many negative symptoms, and such patients do not feel well. I suggest lowering the dose in any patient who has developed insomnia, shakiness, irritability, palpitations, overheating, etc..
