SIDE EFFECTS: Liothyronine therapy generally is well-tolerated. If symptoms occur, they usually occur because there are toxic (too high) levels of thyroid hormone (hyperthyroidism).

Symptoms of hyperthyroidism include:

Women also may experience irregular menstrual cycles.

Since thyroid hormone affects heart rate and metabolism, the impact of treatment of thyroid hormone on the control of diseases such as atrial fibrillation, diabetes and high cholesterol levels always should be considered.



PREPARATIONS: Tablets: 5, 25, and 50 mcg. Injection: 10 mcg/ml

STORAGE: Tablets should be stored at room temperature 20 C - 25 C (68 F - 77 F) and the injectable preparation between 2 C - 8 C (36 F - 46 F )

DOSING: The usual starting dose of liothyronine for treating hypothyroidism is 5 to 25 mcg per day. The dose then is adjusted based on the patient's response and the blood levels of thyroid hormone. Optimal liothyronine doses are different for each patient and vary depending on the patient's age, weight, symptoms, blood levels of thyroid hormone and underlying conditions such as heart disease. Individuals who are hypothyroid will require thyroid hormone for life.
