Elizabeth’s Question:
I just got my lab results back and they are: TSH, Thyroid-stimulating hormone, is 1.33, Free T4 is 1.64, Free T3 is 2.9, thyroid peroxidase antibodies, that’s for the Hashimoto’s, is 16. My doctor said my Free T4 was a little high so she suggested cutting my levothyroxine, which is a T4 only medication, 50 micrograms in half, which would be 25 micrograms and to come back in a couple of months for labs. Do you think my Free T3 levels are low? I’ve been having terrible issues with my muscles and heart palpitations. –Elizabeth.
Short Answer:
Lowering her dosage is a common reaction, but is not the right one. In this case, we would most likely switch the medication to a compounded, sustained-release combination of T4 and T3. As for the heart palpitations, it is probably not related to her medication because the dose is only 50 mcg. Women in perimenopause and going into menopause will commonly experience heart palpitations and be related to adrenal dysfunction and declining estrogen levels.

Dr. Maki: Hello, everyone. Thank you for joining us for another episode of the Progress Your Health podcast. I’m Dr. Maki.
Dr. Davidson: And I’m Dr. Davidson.
Dr. Maki: How are you doing today?
Dr. Davidson: I’m doing great this morning. Thank you. It’s springtime, the birds are singing. The flowers are blooming, the weather’s finally getting to be about 50 degrees, which is good here, which is actually really, really good.
Dr. Maki: Yes, we can’t complain. There’s been less rain, more sun, that’s always fun. The weather’s definitely picking up, now, it’s interesting here in Bellingham where we live. There’s not a lot of difference between– like winter it averaged, this, at least this winter anyway, which I thought was odd. It averaged 40 degrees almost the entire winter which is pretty nice. I’m originally from Minnesota, Wisconsin area and 40 degrees in the wintertime is there wouldn’t be any snow, there wouldn’t even be winter if it was 40 degrees all year. So, we got pretty lucky this winter.
Dr. Davidson: And your sister, my sister-in-law, she still lives in Minnesota. When I send her the– you know, “how warm it is?” I’m like, “Oh, it’s cold. It’s 41.” And she’s like, “That’s t-shirt weather.”
Dr. Maki: Yes, yes yes, she thinks worse, and living in Las Vegas, like we did for so long. We’re getting acclimated certainly to the northwest and I think we’ve transitioned pretty well, but she still thinks we’re wimps when it comes to the weather. I don’t consider that. I think that back there, I think the weather is just a little bit ridiculous. It’s not as bad as it used to be like, I remember being a kid, and it was in January, it was always below zero all the time. Just frigid temperature, it doesn’t seem like it gets that cold anymore like it used to.
