What Is Cytomel Thyroid Medication?

Treated children may manifest a period of catch-up growth, which may be adequate in some cases to normalize adult height. 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 https://malagaallincludedcarhire.com/blog/toremifene-shows-promising-results-as-a-potential/ 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]. CYTOMEL tablets contain the active ingredient, liothyronine (L-triiodothyronine or LT3), a synthetic form of a thyroid hormone liothyronine in sodium salt form.

The recommended dose is 75 mcg to 100 mcg daily for 7 days, with radioactive iodine uptake being determined before and after the 7 day administration of CYTOMEL.
Current information shows that this drug may be used during pregnancy.
CYTOMEL is indicated as a replacement therapy in primary (thyroidal), secondary (pituitary), and tertiary (hypothalamic) congenital or acquired hypothyroidism.

The usual starting dose of liothyronine for treating hypothyroidism is 5 to 25 mcg per day. The dose then is adjusted based on the patient’s response and the blood levels of thyroid hormone. Optimal liothyronine doses are different for each patient and vary depending on the patient’s age, weight, symptoms, blood levels of thyroid hormone and underlying conditions such as heart disease. Individuals who are hypothyroid will require thyroid hormone for life. Because of the increased prevalence of cardiovascular disease among the elderly, initiate CYTOMEL at less than the full replacement dose [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS]. In adult patients with primary hypothyroidism, monitor serum TSH periodically after initiation of the therapy or any change in dose.

Cytomel – Uses, Side Effects, and More

You meet with a doctor from your computer or smartphone to get a comprehensive evaluation, diagnosis, and prescription for medications like Cytomel, if appropriate. For Cytomel to work most effectively, you should take it the same way every day. The amount of medicine that you need is exact, so the way you take it can affect how much medicine your body absorbs. Always take your medication exactly as your doctor prescribes.

It is chemically designated as L-Tyrosine, O-(4-hydroxy-3-iodophenyl)-3,5-diiodo-, monosodium salt. The molecular formula, molecular weight and structural formula of liothyronine sodium are given below. In children with severe or prolonged hypothyroidism, catch-up growth may not be adequate to normalize adult height [see Adverse Reactions (6)]. 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 (2.3)].

Cytomel (Liothyronine)

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. 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. Drugs with thyroid hormone activity, alone or together with other therapeutic agents, have been used for the treatment of obesity. Assess the adequacy of therapy by periodic assessment of laboratory tests and clinical evaluation.

In pediatric patients in whom a diagnosis of permanent hypothyroidism has not been established, discontinue thyroid hormone for a trial period, but only after the child is at least 3 years of age. Obtain serum TSH, T4, and T3 levels at the end of the trial period, and use laboratory test results and clinical assessments to guide diagnosis and treatment, if warranted [see DOSAGE AND ADMINISTRATION]. Addition of thyroid hormone therapy in patients with diabetes mellitus may worsen glycemic control and result in increased antidiabetic agent or insulin requirements. Carefully monitor glycemic control after starting, changing, or discontinuing CYTOMEL [see DRUG INTERACTIONS]. Titrate the dose of CYTOMEL carefully and monitor response to titration to avoid these effects [see DOSAGE AND ADMINISTRATION]. Monitor for the presence of drug or food interactions when using CYTOMEL and adjust the dose as necessary [see DRUG INTERACTIONS and CLINICAL PHARMACOLOGY].

RxList does not provide medical advice, diagnosis or treatment. The major pathway of thyroid hormone metabolism is through sequential deiodination. Approximately 80% of circulating T3 is derived from peripheral T4 by monodeiodination. The liver is the major site of degradation for both T4 and T3. Thyroid hormones are also metabolized via conjugation with glucuronides and sulfates and excreted directly into the bile and gut where they undergo enterohepatic recirculation.

Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. CYTOMEL has a rapid onset of action and residual effects of the other thyroid preparation may persist for the first several weeks after initiating CYTOMEL therapy. When switching a patient to CYTOMEL, discontinue levothyroxine therapy and initiate CYTOMEL at a low dosage. Gradually increase the CYTOMEL dose according to the patient’s response. The recommended starting dosage is 5 mcg once daily, with a 5 mcg increase every 3 to 4 days until the desired response is achieved.

Liothyronine is also given as part of a medical test for thyroid disorders. Liothyronine is a man-made form of a hormone that is normally produced by your thyroid gland to regulate the body’s energy and metabolism. Liothyronine is given when the thyroid does not produce enough of this hormone on its own. Other side effects not listed may also occur in some patients.
