I take Eutroxsig (synthetic T4) for Hashimoto's thyroiditis but I had read good things about Armour so I tried it. I wasn't absorbing this medication so I had to switch back to synthetic.
After reading your post I was curious as to whether the 150 mcg dosage is effectively relieving your hypo symptoms? If you look through this listing of 26 typical hypo symptoms, do you still have any of these? The reason I ask is that a majority of patients taking large doses of T4 meds do not adequately convert T4 to T3, resulting in a Free T3 level that is too low in the range and causes hypo symptoms.

I have been diagnosed having an under active thyroid about 1.5 years ago, my results being "borderline". I am now on 50mg of levothyroxine sodium. Recently I have developed a itchy red rash and it keeps on spreading! Please help! Is this an affect of levothyroxine?

s use levothyroxine rather than thyroxine in their thyroid medications? I have noticed that the levothyroxine has a sodium atom, heavier molar wieght and different structural formula. Isomers are known not to function like the parent compound. So why levothyroxine and not thyroxine in thyroid meds?
Here is part of some information.
The central role of iodide in thyroid physiology has been known for many years. The four iodine atoms of l-thyroxine (T4) constitute 65 percent of its weight; the three iodine atoms of triiodothyronine (T3) constitute 59 percent of its weight. Iodine is a trace element in the crust of the earth and its distribution is quite variable.

I am taking Levothyroxine Sodium every morning, on an empty stomach. I know I am not to take the medicine with drinks such as orange juice, but rather take it with water. My question is, can I add Mio, calorie-free water enhancer to my water and get the same results as taking the medicine with plain water? It's easier for me to drink more water if I add the flavoring.
Levothyroxine sodium is unstable in the presence of light, temperature, air, and humidity. Unless the manufacturing process can be carefully and consistently controlled, levothyroxine sodium products may not be fully potent through the labeled expiration date, or be of consistent potency from lot to lot.

I found out last week I have hypothyroidism, I started levothyroxine sodium also last week. I'm on alesse birth control and was due to start my period yeasterday and didn't get it, it's always on time. The last time I had sex was in may and I used both a condom and the pill but I was late for the pill a few times that month, is it a higher possibility of pregnancy or just a late period from the new medication?
“For most patients older than 50 years or for patients under 50 years of age with underlying cardiac disease, an initial starting dose of 25-50 mcg/day of levothyroxine sodium is recommended, with gradual increments in dose at 6-8 week intervals, as needed.
The recommended starting dose of levothyroxine sodium in elderly patients with cardiac disease is12.5-25 mcg/day , with gradual dose increments at 4-6 week intervals. The levothyroxine sodium dose is generally adjusted in 12.
0) and my T4 was 12 (ref 10 - 25), my GP wanted a second opinion on the matter as did not want to prescribe Levothyroxine until all other tests (Addisons etc) was done.
My Endocrinoligst came up with similar TFT results and all other bloodwork was clear, so suggested a trial of 50mcg of Levothyroxine.
6 months later at follow up my TFTs showed TSH was 0.17 (ref 0.40 - 5.0) and T4 18 (ref 10 - 25), this resulted in a diagnosis of subclinical hypothyroidism and I was told to continue on 50mcg.
I was found to have mild hypothyroidism and was prescribed Levothyroxine sodium 50mcg daily by my doctor. I started taking the medicine and a week later, I had severe gas problem in my abdomen (more in the lower abdomen) and muscle cramps at the lower back region. I thought it was due to some foodstuff related gas problem. It persisted for 2 days. When I took simethicone (Phazyme 180mg softgel), the bloaty feeling subsided and muscle cramps subsided.
