Hypothyroidism
A condition resulting from decreased production of thyroid hormones.
Thyroid hormones
Thyroid hormones are two hormones produced and released by the thyroid gland, namely triiodothyronine and thyroxine. They are tyrosine-based hormones that are primarily responsible for regulation of metabolism. T₃ and T₄ are partially composed of iodine. A deficiency of iodine leads to decreased production of T₃ and T₄, enlarges the thyroid tissue and will cause the disease known as sim…
What is the goal of therapy for hypothyroidism?
The goal of therapy is restoration of the euthyroid state, which can be readily accomplished in almost all patients by oral administration of synthetic thyroxine (T4, levothyroxine). Appropriate treatment reverses all the clinical manifestations of hypothyroidism.
What is the goal of thyroid hormone replacement?
THYROID HORMONE REPLACEMENT THERAPY. The goal of thyroid hormone treatment is to closely replicate normal thyroid functioning. Pure, synthetic thyroxine (T4) works in the same way as a patient’s own thyroid hormone would. Thyroid hormone is necessary for the health of all the cells in the body.
Which hormone replacement therapies are used in the treatment of hypothyroidism?
Cooper DS. Combined T4 and T3 therapy--back to the drawing board. JAMA 2003; 290:3002. Escobar-Morreale HF, Botella-Carretero JI, Gómez-Bueno M, et al. Thyroid hormone replacement therapy in primary hypothyroidism: a randomized trial comparing L-thyroxine plus liothyronine with L-thyroxine alone.
When starting a patient with hypothyroidism on thyroid replacement hormones?
When starting a patient with hypothyroidism on thyroid replacement hormones patient education would include: 1. They should feel symptomatic improvement in 1 to 2 weeks. 2. Drug adverse effects such as lethargy and dry skin may occur. 3. It may take 4 to 8 weeks to get to euthyroid symptomatically and by laboratory testing. 4.
What goals treat hypothyroidism with thyroid replacement?
The treatment goals for hypothyroidism are to reverse clinical progression and correct metabolic derangements, as evidenced by normal blood levels of thyroid-stimulating hormone (TSH) and free thyroxine (T4). Thyroid hormone is administered to supplement or replace endogenous production.
What is the goal of hypothyroidism treatment?
When thyroid hormone is used to treat hypothyroidism, the goal of treatment is to keep thyroid function within the same range as a person without thyroid problems. This is done by keeping the TSH level in the normal range.
What is the goal of levothyroxine replacement therapy?
(See "Disorders that cause hypothyroidism".) The goal of therapy is restoration of the euthyroid state, which can be readily accomplished in almost all patients by oral administration of synthetic thyroxine (T4, levothyroxine). Appropriate treatment reverses all the clinical manifestations of hypothyroidism.
When starting a patient on levothyroxine for hypothyroidism the patient will need follow up treatment of thyroid function in?
Wait at least 6 weeks to follow up after starting therapy Levothyroxine has a 1-week plasma half-life; a steady state is achieved about 6 weeks (6 half-lives) after the start of treatment or a change in dose.
What is the standard treatment for hypothyroidism?
An underactive thyroid (hypothyroidism) is usually treated by taking daily hormone replacement tablets called levothyroxine. Levothyroxine replaces the thyroxine hormone, which your thyroid does not make enough of. You'll initially have regular blood tests until the correct dose of levothyroxine is reached.
What is the best treatment for hypothyroidism?
The best treatment for hypothyroidism is pure synthetic T4 (levothyroxine sodium). It works just like your thyroid hormone and has few, if any, noticeable side effects....Treatments for hypothyroidismLevothroid.Levoxyl.Synthroid.Unithroid.
When is thyroid replacement therapy used?
Thyroid replacement hormones are used to treat hypothyroidism (low production of thyroid hormone) and myxedema, a condition that is caused by prolonged hypothyroidism. Thyroid replacement hormones prevent thyroid hormone release from cancerous thyroid nodules and are used therefore to treat thyroid cancers.
What is first line treatment for hypothyroidism?
American Thyroid Association Continues to Recommend Levothyroxine as First-Line Therapy for Hypothyroidism.
What precautions are needed with thyroid replacement therapy?
Take your thyroid medicine at least 1 hour before breakfast and any calcium or iron medicines you may take. Or take at bedtime, or at least 3 hours after eating or taking any calcium or iron medicines. Tell your healthcare provider of your thyroid hormone treatment before beginning treatment for any other disease.
What are the recommendations for initiating thyroid hormone replacement for a newly diagnosed hypothyroid patient?
For most cases of mild to moderate hypothyroidism, a starting levothyroxine dosage of 50-75 µg/day will suffice. Clinical benefits begin in 3-5 days and level off after 4-6 weeks. Achieving a TSH level within the reference range may take several months because of delayed readaptation of the hypothalamic-pituitary axis.
When do you recheck thyroid levels after starting levothyroxine?
A TSH blood test should be obtained at least every 6-12 months while you are on a stable thyroxine dose, and more often if your dose is changed. Your doctor will usually wait 6-8 weeks after a thyroxine dose adjustment to measure your TSH, when the levels of thyroxine have reached a steady state.
Which of the thyroid preparation is preferred for the maintenance of replacement therapy?
Synthetic levothyroxine (L-T(4)) has many advantages: in view of its long half-life, once-daily administration suffices, the occasional missing of a tablet causes no harm, and the extrathyroidal conversion of T(4) into T(3) (normally providing 80% of the daily T(3) production rate) remains fully operative, which may ...
Why do we need thyroid hormone replacement?
Hypothyroidism, is the most common reason for needing thyroid hormone replacement. The goal of thyroid hormone treatment is to closely replicate normal thyroid functioning. Pure, synthetic thyroxine (T4) works in the same way as a patient’s own thyroid hormone would. Thyroid hormone is necessary for the health of all the cells in the body.
What is thyroid hormone therapy?
THYROID HORMONE TREATMENT. Thy roid hormone is used in two situations: to replace the function of the thyroid gland, which is no longer functioning normally ( “replacement therapy “) and. to prevent further growth of thyroid tissue (“ suppression therapy “). Suppression therapy is used primarily in patients with thyroid cancer to prevent recurrence ...
What is the treatment for thyroid cancer?
After surgery for thyroid cancer, thyroid hormone is needed both to replace the function of the removed thyroid gland and to keep any small or residual amounts of thyroid cancer cells from growing (see Thyroid Cancer brochure ). Thyroid hormone suppression therapy is also an important part of the treatment ...
Why is thyroid hormone suppression used?
In the past, thyroid hormone suppression therapy was used to prevent benign thyroid nodules and enlarged thyroid glands from growing . More recent evidence has shown that this practice is not effective in regions of the world that have adequate iodine intake (such as the USA).
What medications can cause thyroid problems?
Medications that can potentially cause people to need a different dose of thyroid hormone include birth control pills, estrogen, testosterone, some anti-seizure medications ( for example Dilantin and Tegretol ), and some medications for depression.
Why is thyroid hormone different from other medications?
Therefore, taking thyroid hormone is different from taking other medications, because its job is to replace a hormone that is missing. The only safety concerns about taking thyroid hormone are taking too much or too little.
How to make sure thyroid hormone is correct?
The physician will make sure the thyroid hormone dose is correct by performing a physical examination and checking TSH levels. There are several brand names of thyroid hormone available.

What is the therapeutic range for hormone replacement?
Screening values are much narrower than the acceptable range used to keep a person stable on hormone replacement. 3. Therapeutic values are kept between 0.05 and 3.0 ideally. Screening values are considered acceptable up to 10. 4.
What is the ratio of T4 to TSH?
Most needs to be T4 to mimic natural ratios of hormone. 3. The ratio is unimportant. 4. The mix needs to be 50-50 at first. 2. Laboratory values are actually different for TSH when screening for thyroid issues and when used for medication management.
