In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. CYTOMEL is indicated as an adjunct to surgery and radioiodine therapy in the management of well-differentiated thyroid cancer. If it is near the time of the next dose, skip the missed dose. Do not double the dose to catch up unless your doctor instructs you to do so. Ask your doctor ahead of time what to do about a missed dose and follow your doctor’s specific directions.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine. If you use medicine to treat high cholesterol (including cholestyramine, colesevelam, colestipol), Kayexalate®, or sevelamer, take liothyronine at least 4 hours before you take any of these medicines. Liothyronine is also used in some medical tests to help diagnose problems with the thyroid gland.

For non-prescription products, read the label or package ingredients carefully. The signs and symptoms of overdosage are those of hyperthyroidism [see WARNINGS AND PRECAUTIONS and ADVERSE REACTIONS]. Cerebral embolism, seizure, shock, coma, and death have been reported. Symptoms may not necessarily be evident or may not appear until several days after ingestion. Dosing adjustments are based on an assessment of the individual patient’s clinical and laboratory parameters [see DOSAGE AND ADMINISTRATION]. To treat mild hypothyroidism the recommended starting dose of Cytomel is 25 mcg daily.

  • ​Assess the adequacy of therapy by periodic assessment of laboratory tests and clinical evaluation.
  • If you take lanthanum, take it at least 2 hours before or after liothyronine.
  • Closely monitor patients to avoid undertreatment and overtreatment.
  • If you think you have become pregnant while using this medicine, tell your doctor right away.
  • Thyroid hormones exert their physiologic actions through control of DNA transcription and protein synthesis.

The dosage is based on your medical condition, age, lab test results, and response to treatment. When given as part of a thyroid suppression test, you will need to take Cytomel for several days in a row in preparation for the test. Levothyroxine and Cytomel (liothyronine), two thyroid replacement medications, are both recommended to be taken on an empty stomach, around 30 to 60 minutes before breakfast for optimal absorption. However, when it comes to dosing, consistency is key in regard to getting the best and most consistent results. This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using liothyronine.

Liothyronine should not be used for the treatment of obesity or for the purpose of losing weight. This medicine is ineffective for weight reduction and when taken in larger amounts, may cause more serious unwanted effects.

Thyroid hormone dose requirements may increase during pregnancy. 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.

Therefore, a decrease in the dose of anticoagulant may be warranted with correction of the hypothyroid state or when the https://lisolaceliaca.it/new-guide-released-on-where-and-how-to-buy/ dose is increased.

Monitor for cardiac arrhythmias during surgical procedures in patients with coronary artery disease receiving suppressive CYTOMEL therapy.

Infants a few months old may require 20 mcg once daily for maintenance. Above 3 years of age, the full adult dosage may be necessary [see Use in Specific Populations (8.4)]. Appropriate studies performed to date have not demonstrated geriatrics-specific problems that would limit the usefulness of liothyronine in the elderly. However, elderly patients are more likely to have age-related kidney or heart or blood vessel problems, which may require caution and an adjustment in the dose for patients receiving liothyronine. Thyroid hormone increases metabolic clearance of glucocorticoids. Initiation of thyroid hormone therapy prior to initiating glucocorticoid therapy may precipitate an acute adrenal crisis in patients with adrenal insufficiency.

Toxic effects may include increased risk of cardiac arrhythmias and central nervous system stimulation. Administration of sertraline in patients stabilized on CYTOMEL may result in increased CYTOMEL requirements. Hypersensitivity reactions to inactive ingredients have occurred in patients treated with thyroid hormone products. These include urticaria, pruritus, skin rash, flushing, angioedema, various gastrointestinal symptoms (abdominal pain, nausea, vomiting and diarrhea), fever, arthralgia, serum sickness and wheezing. 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.
