Measure serum TSH and free-T4 as soon as pregnancy is confirmed and, at minimum, during each trimester of pregnancy. In patients with primary hypothyroidism, maintain serum TSH in the trimesterspecific reference 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. The starting adult dose of Cytomel (Liothyronine) to treat hypothyroidism is 25µg daily. Do not change the way you take Cytomel (Liothyronine) without consulting your doctor. The thyroid is a small gland at the base of your neck that produces hormones to regulate your body’s energy use.

  • Thyroid hormone is generally continued for life in these patients.
  • Cytomel is a man-made form of a hormone that is normally produced by your thyroid gland to regulate the body’s energy and metabolism.
  • Perform routine clinical examination, including assessment of development, mental and physical growth, and bone maturation, at regular intervals.
  • My PCP never told me that my diet can have an impact on my condition and the severity of my symptoms.
  • The dose of this medicine will be different for different patients.

Thyroid hormone drugs are natural or synthetic preparations containing tetraiodothyronine (T4, levothyroxine) sodium or triiodothyronine (T3, liothyronine) sodium or both. T4 and T3 are produced in the human thyroid gland by the iodination and coupling of the amino acid tyrosine. T4 contains four iodine atoms and is formed by the coupling of two molecules of diiodotyrosine (DIT). T3 contains three atoms of iodine and is formed by the coupling of one molecule of DIT with one molecule of monoiodotyrosine (MIT).

1 Drugs Known to Affect Thyroid Hormone Pharmacokinetics

Pregnancy, infectious hepatitis, estrogens, estrogencontaining oral contraceptives, and acute intermittent porphyria increase TBG concentrations. Nephrosis, severe hypoproteinemia, severe liver disease, acromegaly, androgens and corticosteroids decrease TBG concentration. Familial hyper- or hypo-thyroxine binding globulinemias have been described, with the incidence of TBG deficiency approximating 1 in 9000. CYTOMEL is indicated as an adjunct to surgery and radioiodine therapy in the management of welldifferentiated thyroid cancer. Twenty-five mcg of liothyronine is equivalent to approximately 1 grain of desiccated thyroid or thyroglobulin and 0.1 mg of L-thyroxine.

Cytomel – Uses, Side Effects, and More

Many will also sell the compound over the counter and legally so as long as the purchase is made at the pharmacy. The law truly can vary greatly depending on the country in question. Because of this variance factor, before you buy Cytomel it is imperative you understand the law of the country in question before any purchase is made. The hormones contained in the natural preparations are absorbed in a manner similar to the synthetic hormones. CYTOMEL is contraindicated in patients with uncorrected adrenal insufficiency [see Warnings and Precautions (5.3)]. My PCP never told me that my diet can have an impact on my condition and the severity of my symptoms.

If you buy Cytomel from an RCL, and it will almost always be listed and labeled by its chemical name Liothyronine Sodium, there are also quality issues you need to be aware of. Some RCL’s do a poor job in manufacturing as the compounds often lose potency very fast due to their unstable nature. This should not present any danger, but it can be annoying if you make a purchase and receive an inferior product. There are some great RCL’s on the market, but you need to make sure you research them thoroughly before making a purchase and fully understand the law before any such purchase is made.

In children with severe or prolonged hypothyroidism, catch-up growth may not be adequate to normalize adult height [see ADVERSE REACTIONS]. Serum TSH levels should be monitored and the CYTOMEL dosage adjusted during pregnancy. Since postpartum TSH levels are similar to preconception values, the CYTOMEL dosage should return to the pre-pregnancy dose immediately after delivery [see DOSAGE AND ADMINISTRATION].
