@Dr. Jeff, Our 14 yr old female Havanese (Fibi) has been on .1mg of Levothyroxine 2x/ day for several years, along with some adrenal desiccated supplement.
Her local vet ran a senior panel on her blood and reduced the levo by 50% based on a T-4 of 4.0.
Fibi has been especially lethargic and we're wondering if this was too much of a reduction. Should a full thyroid panel be used rather than just the T-4?
In 2020, her T-4 was 2.7, Free t-4 by ED (ng/dl), Free T-4 by ED (pmol/l).
Thanks for any insight!
