Cytomel T-3 (liothyronine sodium) tablets dosage

An under-active thyroid gland does not produce enough thyroid hormone which causes a condition known as hypothyroidism. This can lead to symptoms such as a pale, puffy appearance, dry coarse skin, brittle hair, a hoarse voice, slow heartbeat, muscle pain, joint pain, weakness, tiredness, constipation, weight changes and an intolerance of cold temperatures. Cytomel T-3 (liothyronin) is given as a medicine to correct this hormone imbalance.

Cytomel T-3 (liothyronine sodium) tablets are intended for oral administration, once-a-day dosage is recommended. Although liothyronine sodium has a rapid cut-off, its metabolic effects persist for a few days following discontinuance.

Cytomel T-3 Recommended dosages:

* 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.
* Congenital Hypothyroidism: Recommended starting dosage is 5 mcg daily, with a 5 mcg increment every 3 to 4 days until the desired response is achieved. 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.
