Liothyronine Sodium Profile:
Liothyronine Sodium belongs to the general group of medicines called thyroid hormones. They are used when the thyroid gland does not produce enough hormone. They are also used to help decrease the size of enlarged thyroid glands (known as goiter) and to treat thyroid cancer.
Use Liothyronine Sodium only as directed by your doctor. Do not use more or less of it, and do not use it more often than your doctor ordered. Your doctor has prescribed the exact amount your body needs and if you take different amounts, you may experience symptoms of an overactive or under active thyroid. Take it at the same time each day to make sure it always has the same effect.
If your condition is due to a lack of thyroid hormone, you may have to take this medicine for the rest of your life. It is very important that you do not stop taking this medicine without first checking with your doctor.
Liothyronine Sodium Dosing:
The dose of Liothyronine Sodium will be different for different patients. Follow your doctor’s orders or the directions on the label. The following information includes only the average doses of these medicines. If your dose is different, do not change it unless your doctor tells you to do so.
The number of tablets that you take depends on the patient. The amount of thyroid hormone that you need to take every day depends on the results of your thyroid tests. However, treatment is usually started with lower doses that are increased a little at a time until you are taking the full amount. This helps prevent side effects.
For replacing the thyroid hormone:
Adults and teenagers – At first, 25 micrograms (mcg) a day. Some patients with very serious conditions caused by too little thyroid hormone may need to take only 2.5 to 5 mcg a day at first. Also, some patients with heart disease or the elderly may need lower doses at first. Then, your doctor may increase your dose a little at a time to up to 50 mcg a day if needed. Your doctor may want you to divide your dose into smaller amounts that are taken two or more times a day.
For treating a large thyroid gland (goiter):
Adults – At first, 5 mcg a day. Some patients with heart disease or the elderly may need lower doses at first. Then, your doctor may increase your dose a little at a time to 50 to 100 mcg a day.
Missed dose of Liothyronine Sodium:
If you are using Liothyronine Sodium regularly and you miss a dose, use it as soon as possible. Then use any remaining doses for that day at regularly spaced intervals. Do not double doses.
