About Synthroid: Synthroid contains the drug levothyroxine. It is a synthetic congener of the naturally occurring hormone thyroxine, which is formed in the thyroid gland. Synthroid is used as a replacement hormone administered when the thyroid gland is not functioning properly. Normally two hormones are secreted by the follicular cells lining the thyroid follicles. These are tri-iodothyronine (T3) and thyroxine (T4) or tetra-iodothyronine. Synthroid, being a synthetically produced analogue of thyroxine, is capable of carrying out all the functions of thyroxine in the body. Low levels of thyroid hormones result in hypothyroidism, characterised by weight gain, lethargy, cold intolerance, sluggish reflexes and impaired mental and physical growth in children, and can be remedied by Synthroid.
How Synthroid Works: Synthroid contains the active ingredient levothyroxine, which acts in a similar manner to the naturally occurring hormone thyroxine or T4. Thyroxine acts by entering cells via thyroid receptors on the surface and inducing the production of proteins by the translation and transcription of DNA by mRNA. Synthroid is administered when the body is deficient in thyroid hormones T3 and T4. This leads to a state called hypothyroidism and requires replacement with external thyroxine in the form of a medication like Buy Synthroid Canada to normalize the status of the thyroid gland. Another use of Synthroid is in the suppression of TSH secretion from the pituitary gland. TSH secretion is suppressed by a negative feedback mechanism. When it is observed that the overproduction of TSH is more harmful than helpful, Synthroid can be used to suppress it. High levels of circulating thyroid hormone over the course of Buy Synthroid therapy will lead to negative feedback and suppression of TSH secretion and stop its adverse effects.
How To Take Synthroid: Hypothyroidism can have many causes, including congenital deficiency, thyroid gland failure, acquired hypothyroidism and hypothyroidism after thyroidectomy (removal of the thyroid gland). Buy Synthroid No Prescription can be used to treat any and all of these conditions since the end result of all these disorders is the same - a deficiency of thyroid hormones. Even when classified as primary (thyroid related), secondary (pituitary related), tertiary (hypothalamus related), or subclinical (raised TSH levels with normal T3 and T4 levels) hypothyroidism, the condition can be treated with Synthroid Without Prescription. When high TSH levels cause goiter, multiple nodules, or multinodular goiter, suppression of TSH with Synthroid Canada is warranted. Synthroid No Prescription is available as tablets with strengths ranging from 25 mcg to 300 mcg. The commonly used strengths are 50 mcg, 100 mcg, or 200 mcg. If required the tablet can be crushed and administered to children as a suspension. For the treatment of hypothyroidism, Buy Synthroid Without Prescription is started at full replacement levels as required. Usually 100 mcg/day is the starting dose and is to be preferably taken in the morning before breakfast as a single daily dose. The dose can also be calculated as per body weight as 1.7 mcg/kg body wt/day. In patients older than 50 years of age, it is better to start with a lower dose of 25-50 mcg/day. The dose can be increased in 2-week intervals with regular monitoring of TSH levels until they return to normal. For TSH suppression higher doses of 2 mcg/kg/day may commonly be required.
