About
Thyroid is a brand name for the drug liothyronine sodium - a thyroid hormone. It is used medically to treat cases of thyroid insufficiency, obesity, certain metabolic disorders and fatigue. Specifically this drug is a pharmaceutical preparation of the natural thyroid hormone triiodothyronine (T-3). When administered, Thyroid increases the patient's metabolism. The result is an increased rate of cellular activity (noted by a more rapid utilization of carbohydrates, fats and proteins).
Usage of Thyroid
- Take Cytomel by mouth with or without food.
- Cytomel works best if it is taken at the same time each day.
- Take Cytomel at least 4 hours apart from calcium salts (eg, calcium carbonate), cholestyramine, or sucralfate.
- Continuous use of Cytomel for a few weeks may be necessary to relieve symptoms of your condition.
- If you miss a dose of Cytomel , take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Dosing of Thyroid
Mild Hypothyroidism: Recommended standing dosage is 25 mcg daily. Daily dosage then may be increased by up to 25 mcg every 1 or 2 weeks. Usual maintenance dose is 25 to 75 mcg daily.
Myxedema: Recommended starting dosage is 5 mcg daily. This may be increased by 5 to 10 mcg daily every 1 or 2 weeks. When 25 mcg daily is reached dosage may be increased by 5 to 25 mcg every 1 or 2 weeks until a satisfactory therapeutic response is attained. Usual maintenance dose is 50 to 100 mcg daily.

Infants a few months old may require only 20 mcg daily for maintenance. At 1 year 50 mcg daily may be required. Above 3 years, full adult dosage may be necessary
