Tirosint is a T4 med. T4 has a 7-day half-life which means it will be a full two weeks before your new dose is fully loaded in your system.

I have never taken it but have read stories of others who found it to be more effective than levothyroxine/Synthroid, etc. This is most likely due to the fact that Tirosint has no fillers to interfere with absorption.

How did your doctor decide on a 137mcg dose?

No matter what, best of luck to you!!

She said it was based on the fact that before I was on 120 mg of Armour I was on 175 mcg. of Synthroid.

Thanks for satisfying my curiosity about the thinking behind the new Tirosint dose size.

I'm glad your doctor started you out on a lower dose. I have read stories of people being driven hyper when their doctors switched them to Tirosint at the same dose they had been taking in the form of Synthroid, etc.

It seems those fillers can really interfere with absorption in some people.

Please keep us posted and, again, best of luck to you!

Hello,
I'm in a bit of a quandary. I was originally diagnosed with hypothyroidism by my family doctor, but had issues with Levothyroxine, so my endocrinologist suggested tirosint. I was also put on a fairly high dose of liothyronine. Then a week ago my endocrinologist ran some blood work and almost doubled my tirosint, but reduced my liothyronine down from 3 three times daily to 2 once daily, and since then I've started gaining weight again (only eating between 1000 to 1400 calories daily), my body temperature is dropping drastically, and I'm basically not sleeping again but always tired.

Whenever I ask my endocrinologist questions he just says it's probably either my imagination or due to something else, reduce my calories, increase my exercise and I should be okay. He doesn't believe me when I tell him I already record everything I eat daily. He looks at my size, they always have. When all this started I more than doubled in size in under six months without changing my dietary intake. My hair fell out in droves, my nails became extremely brittle and my once extremely oily skin dried out like a desert.

Doctors claimed it wasn't my thyroid, even though I told them I also couldn't sleep more than an hour at a time, felt cold, and seriously depressed. Instead I was diagnosed with depression, but after six years and eight different depression medications I was told I was one of those resistant to medication therapy and would have to figure this all out on my own.

Now I realize I'm a bit long winded, but I have always had a problem being heard by my doctors. So I guess my question is should I already be feeling such negative effects from the reduction in liothyronine, or could it be that it was cut back too drastically? I think it was, but getting my endocrinologist to acknowledge this is going to be difficult, at best if it is.
thanks
