CYTOMEL® liothyronine sodium Patient information US
20–25micrograms of liothyronine sodium is equivalent to approximately 100 micrograms of levothyroxine sodium. An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about https://dichthuat.org.vn/steroid-16/glucosamine-chondroitin-60-capsules-how-to-buy.html how any drug interactions are being managed or should be managed. Check with your doctor if you notice any symptom that worries you while you are taking Cytomel (Liothyronine). The following side effects have been reported by at least 1% of people taking Cytomel (Liothyronine). The side effects listed below are not experienced by everyone who takes Cytomel (Liothyronine).
- If you’re taking thyroid hormone replacement for hypothyroidism, you may want to avoid consuming certain foods within a few hours of taking your thyroid medication.
- No special precautions appear to be necessary when oral anticoagulant therapy is begun in a patient already stabilized on maintenance thyroid replacement therapy.
- You’ll want to have your full thyroid panel measured before and during dose titration trials.
- It is important to take this medication exactly as prescribed by your doctor.
- Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist.
What conditions is Cytomel approved to treat?
Cytomel (liothyronine sodium) Tablets can be used in patients allergic to desiccated thyroid or thyroid extract derived from pork or beef. Both protein-bound hormones exist in reverse equilibrium with minute amounts of free hormone, the latter accounting for the metabolic activity. When pregnant women used Cytomel, their babies did not show any problems related to this medication.
Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them. Generally speaking Cytomel is a very safe thyroid medication, but abuse, particular high dose long term exposure can be life threatening. I recommend that you also investigate the possibility that something else is interfering with the absorption of your thyroid medication, such as fillers like gluten, or certain supplements that you are taking. If you feel that you may have received an inaccurate lab result (perhaps you’ve realized the timing of your thyroid medication may have interfered with its accuracy), there are steps you can take to receive a more accurate result. As mentioned above, taking any medication with T3 will first drop TSH levels for around five hours before they start rising again.
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. 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. In adult patients with primary hypothyroidism, monitor serum TSH periodically after initiation of the therapy or any change in dose. To check the immediate response to therapy before the TSH has had a chance to respond or if your patient’s status needs to be assessed prior to that point, measurement of total T3 would be most appropriate.
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. Concurrent use of tyrosine-kinase inhibitors such as imatinib may cause hypothyroidism. CYTOMEL may reduce the therapeutic effects of digitalis glycosides. Serum digitalis glycoside levels may be decreased when a hypothyroid patient becomes euthyroid, necessitating an increase in the dose of digitalis glycosides.
Cytomel’s active ingredient, liothyronine sodium, is a synthetic form of the T3 hormone that directly provides the active thyroid hormone your body needs. Hypothyroidism decreases and hyperthyroidism increases the sensitivity to oral anticoagulants. Prothrombin time should be closely monitored in thyroid-treated patients on oral anticoagulants and dosage of the latter agents adjusted on the basis of frequent prothrombin time determinations. In infants, excessive doses of thyroid hormone preparations may produce craniosynostosis. 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 (2.6).
Will Cytomel Cause Hair Loss?
Failure of the serum TSH to decrease below 20 IU per liter after initiation of CYTOMEL therapy may indicate the child is not receiving adequate therapy. Assess compliance, dose of medication administered, and method of administration prior to increasing the dose of CYTOMEL see Warnings and Precautions (5.1) and Use in Specific Populations (8.4). 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. Infants a few months old may require 20 mcg once daily for maintenance.
Fortunately, I think we’ve made some progress since 2013, and many more practitioners are opening up to the idea of using T3 medications. The earlier concerns relating to the issue with fillers, the need for adherence to usage guidelines, and the potential ineffectiveness due to poor T4/T3 conversion, apply to Synthroid as well. Conventional doctors will be very familiar with this top branded medication. Check out the articles linked above to learn more about supplements to optimize selenium and zinc levels. These side effects tend to be dose-dependent so whether or not you will see good or bad side effects depends on how much you are taking.
Cytomel is a brand name for liothyronine, which is a synthetic form of the thyroid hormone triiodothyronine (T3). It works by supplementing or replacing the T3 hormone in your body, which can be beneficial if your thyroid does not produce enough on its own. Liothyronine was first approved by the FDA in 1956 and it’s often used when levothyroxine (T4) alone doesn’t seem to be managing hypothyroid symptoms adequately. It can be used in conjunction with other thyroid medications or by itself and it can also be compounded in various forms to delay its release into the bloodstream. One thing you need to understand about thyroid medications is that generally, you should NOT be experiencing negative side effects when you take these medications. Cytomel comes in doses of 5, 25, and 50 mcg, and the most common use of the medication is in combination T4-T3 therapy, where a patient takes levothyroxine (synthetic T4) along with the Cytomel.
