Công dụng thuốc Cytomel

Therefore, individuals who are hypothyroid will eliminate drugs more slowly, and those with hyperthyroidism will eliminate drugs faster compared with individuals with normal levels of thyroid hormone. Liothyronine sodium is a synthetic (man-made) version of one of the two hormones made by the thyroid gland, triiodothyronine. It is used for treating individuals who are hypothyroid (do not produce enough thyroid hormones). Thyroid hormones increase the metabolism (activity) of all cells in the body. In the fetus, newborn infant and child, thyroid hormones promote growth and development of tissues.

In patients with primary hypothyroidism, maintain serum TSH in the trimesterspecific reference range. For patients with serum TSH above the normal trimester-specific range, increase the dose of thyroid hormone and measure TSH every 4 weeks until a stable dose is reached and serum TSH is within the normal trimester-specific range. Reduce thyroid hormone dosage to prepregnancy levels immediately after delivery and measure serum TSH levels 4 to 8 weeks postpartum to ensure thyroid hormone dose is appropriate. After surgery for differentiated thyroid cancer, thyroid hormone is needed both to replace the function of the removed thyroid gland and to prevent thyroid cancer cells from growing (see Thyroid Cancer brochure). Thyroid hormone suppression therapy is an important part of the treatment of thyroid cancer and is effective in inhibiting the growth of microscopic thyroid cancer cells or residual thyroid cancer. In this case, patients usually require a higher dose than is typical for replacement.

• Estrogens tend to increase serum thyroxine-binding globulin (TBg).
• Use of oral thyroid hormone drug products is not recommended to treat myxedema coma.
• Beyond that, though, small margins can be damaging in their own right.
• Individuals who are hypothyroid have slower theophylline elimination.

Description for Cytomel

Also tell them if you smoke, drink alcohol, or use Growth hormone illegal drugs. Cytomel is not the only option for patients requiring T3 supplementation. Generic liothyronine is available and may be a more affordable choice.

Drug Interactions

Studies are underway to provide more information on the benefits and best dosing of combination therapy. A trial period of 3 – 6 months may be reasonable to determine if combination T4 and T3 therapy will help. Drug interactions may change how your medications work or increase your risk for serious side effects. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor’s approval. Phenobarbital has been shown to reduce the response to thyroxine.

In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive. Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of liothyronine in children.

Serum TSH is not a reliable measure of CYTOMEL dose adequacy in patients with secondary or tertiary hypothyroidism and should not be used to monitor therapy. Use the serum T3 level to monitor adequacy of therapy in this patient population. Increase the dose by 25 mcg daily every 1 or 2 weeks, if needed. Cytomel (liothyronine sodium) Tablets contain liothyronine (L-triiodothyronine or LT3), a synthetic form of a natural thyroid hormone, and is available as the sodium salt.

With T3 medications, I recommend starting with a low dose and slowly increasing it. Some individuals may also consider sustained release, compounded versions of T3. Having an impaired gut, stress, and/or any of other reasons shown in the earlier T4 to T3 conversion graphic, can make a T4-only medication ineffective. We can see signs of poor conversion happening when we look at a full thyroid lab panel, as mentioned earlier. In my reader’s survey, 25 percent of respondents said they felt better on Levoxyl, with 63 percent experiencing improvements in their labs. Another 55 percent saw improvements in energy, 27 percent improvements in hair loss, and 42 percent improvements in mood.

Dr. C’s gift for figuring out what works has helped hundreds of thousands reverse thyroid disease, heal their adrenals, and lose weight naturally. The drawback with compounded thyroid is that it is simply not standardized, which means that the results are not exacting enough to feel confident about the product. Given this, it cannot possibly provide the right benefits for patients consistently. In terms of practical application, using the results my patients get from using the thyroid conversion calculator, I am often asked which thyroid types I am likely to recommend the best. Let me begin with those I do not recommend, though, and that starts with compounded thyroid. Right now, the best thing you can do for your thyroid care is to carefully talk through your options with your healthcare provider.
