Levothyroxine is very pure, and has negligible side-effects when taken in the correct dose. Levothyroxine doses are dependent upon the persons body weight. Most patients require between 100 and 150 micrograms a day, but the dose can be lower than 75 micrograms or up to 300 micrograms a day, depending on your needs.
This is the pituitary's effort to return the system to "normal" and normalize thyroid function. So, a TSH that is higher than normal suggests a thyroid that is underactive and not doing its job of producing enough thyroid hormone.
In most patients this will be associated with a thyroid-stimulating hormone (TSH) reading in the lower part of the reference range and a level of thyroxine (T4) in the blood towards the upper part or even slightly above the reference range.
Some medicines - prescribed and over-the-counter - can affect results, so it is important to tell your doctor about any medication you are taking. What is mild thyroid failure or subclinical hypothyroidism?
Synthetic thyroxine aids in maintaining thyroid hormone balance, which helps stop the symptoms of hypothyroidism and promotes proper health and wellness.
Synthethic versus Natural The only difference between natural thyroxine from synthetic thyroxine is that natural thyroxine is made by the body. The production of natural thyroxine is controlled by the feedback system involving the hypothalamus, the thyroid glands and pituitary glands.
These medications supplement the lack of thyroxine in the body by providing synthetic hormones that are identical to thyroxine itself. While these medications are generally effective they may cause side effects.
You should have a regular thyroid function test and consult your doctor if you notice any symptoms, as you may benefit from treatment. What is the treatment for hypothyroidism? Your doctor will prescribe levothyroxine, a synthetic version of the thyroxine produced by the thyroid gland.
Mary Shomon Updated December 28, 2015. Readers regularly write to me asking that I explain "why, when my TSH results show that my TSH is low, does the doctor want to LOWER instead of RAISE my medicine?" Or, "doesn't a high TSH mean I have too much thyroid?
Low levels of thyroid hormone result in a slowing down of the mental and physical processes of the whole body. Once treatment has started these symptoms will improve over time, but if not, you should talk to your doctor.

During this period you will have regular thyroid function tests, usually every six to eight weeks. Levothyroxine is best taken in the morning, with water, on an empty stomach, at least half an hour before eating and drinking anything.
Low Thyroxine Hormone Level When thyroxine level falls lower than the acceptable level, the person may start to manifest symptoms of hypothyroidism. Low levels of thyroid hormones are caused by the underactive thyroid gland, and the symptoms usually are: Dry, cool skin Loss of concentration.
This is an issue that is still under debate. When you are being treated for hypothyroidism with thyroid hormone replacement drugs, doctors will typically attempt to medicate you into this so-called "normal" reference range - of a TSH from.3/.5 on the low end, to on the high end.
When the thyroid gland produces excess thyroxine, the individual may suffer from hyperthyroidism. When a person is deficient with this kind of hormone, on the other hand, he or she will suffer from hypothyroidism.
Question: I recently had my blood work done and received my results. My TSH levels came back pretty low at 0.13 mU/l. My doctor has me on some medication called Thyroxine which is supposed to replace the hormones that I am deficient in.
