Yes I think you should. In order to get rid of the excess thyroid hormone you are taking your body is creating lots of reverse T3, and that will make you feel very unwell eventually. The high Free T3 won't help either. You may be coping at the moment but it won't last.
I don't know the best way of cutting doses. Stopping your meds altogether for a few days would be the best way of getting rid of the excess quickly, but you are likely to end up with your heart going very fast for a while as the Free T3 runs out. I don't know of a way of avoiding that. Perhaps someone else does.
Depending on how you react you should start your meds again at a dose of, say, 1.5 grains, and raise according to the instructions in the previous link I gave, or this one :
You are over medicated to have FT3 over range 12+ hours after your last dose. There's no need to switch to NatureThroid if you are otherwise happy on Thiroyd, simply reduce your dose to 3 grains.
Thyroid antibodies are negative for autoimmune thyroiditis (Hashimoto's).
High ferritin can indicate inflammation or infection in the body. Your ferritin is mildly elevated, possibly because of a cold or virus at the time of testing.
B12, folate and VitD are good.
I suggest you Google "Urea Nitrogen low" and "ALT high" etc. for explanations of abnormal evaluations. labtestsonline.org is a good resource.
Actually no, when you're over medicated you don't need to reduce slowly. I would skip NDT for 3-4 days to wash out the higher dose and then resume 3 grains daily.
My hair was coming out in clumps when my FT3 was high. It took about 7 weeks after reducing dose for shedding to start slowing down and a few more weeks to completely stop. Counterintuitive, but being overmedicated may also be why you are tired.
My endo told me to go a couple of days without meds then a much lower dose for 10 days and then slowly raise in quarters if I felt it necessary I dropped down at 3 to 1.5 and not to go above 1.75. He was almost spot on and now more than happy on 1.75 two days and 2.0 on the third plus I take my temp every morning and also at 3 pm when I remember which isn't very often!
Thanks for your reply. I did not know that. I was told that I can increase my does till my hypo symptoms disappear. But they did not go away. Still have all hypo symptoms. However, my body is warm now and really like it. As I was always cold.
Could you please tell me how did you decrease you dose?
It's been more than 2 months that I am on 4 grains. I was afraid to raise it to 4 1/2 because it seemed very high to me. So I stayed on 4 grains till I got health insurance and could do my blood test.
I am wondering why I did not have hyper symptoms. I remember when I was on 3 1/2 grains I had heart palpitation and I thought I was under medicated. After I added another half grain it went away.
I am going to get boring with this but are you taking anything with biotin in it? It can give false low TSH and false high t3 t4 by interacting with some lab tests for thyroid. Just a thought 🙂
I think itsoften difficult to find the right place and have found being slightly over is as bad as being slightly under so if unsure I always drop my dose down squarer for a. Outlet of weeks. That will show you if you have gone the right way. Just increasing doesn't make you fell better unless you were under medicating
