Question: Hi there,
I have Hashimotos for the last 15 years and take Synthroid. I never had problems with symptoms until recently. I finally am feeling a little better after learning that I was on way too much Synthroid and then way too little Synthroid. I still don't feel GREAT, but I feel a lot better than I was. My current dose of Synthroid is .112 mcg Monday through Friday and .100mcg on Saturday and Sunday. This dose seems to be doing well with me. I do have symptoms some days, but I have more good days than bad. About 3 months ago, my new doctor tested my reverse t3 and said that it was borderline high at 24.5, so she added Cytomel to my regimen and I only took it for 2 days and could not take it. It sent my heart racing and pounding. My doctor told me to stop taking it because my heart rate was too high. I have been doing ok and had my labs drawn this week. My tsh is 0.5, my Free t4 is 1.79 and my reverse t3 is 25.5. Because I have been feeling a little hyperthyroid, she told me to take .112mcg 4 days a week and in between, take .100mcg 3 days per week. Can having a borderline high Reverse T3 hurt me? Can I just live with it that way forever? I don't want any long term damage to my body. Thank you!

So I should not worry about the reverse t3 numbers, correct? These are not important? I just want to make sure. I do have mild anxiety and have a toxic reaction to SSRIs and SNRIs. I cannot take them, so I have to try to handle my anxiety in other ways. I tend to only get anxiety when my thyroid levels are off and I am overmedicated since I wake up in the morning with a racing heart and pressure in my throat. When my thyroid levels are right, I have no anxiety symptoms. I am going to use synthroid 112 4 days and 100 for 3 days. I just wanted to make sure that having an abundance of reverse t3 can't hurt me physically.

Thank you so much! I do feel better when I exercise. I usually do bike riding 4-5 miles per day. When I miss those days, I feel bad. Thank you again! I will try not to worry about it.
