liothyronine sodium, Cytomel, Triostat (cont.)

NURSING MOTHERS: Very small amounts of thyroid hormone may be excreted in breast milk. This is not a serious problem for breastfed infants.

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: chest pain, increased heart rate, excessive sweating, heat intolerance, nervousness, headache, tremor, insomnia, diarrhea, vomiting, weight loss, fever, and, rarely, cardiac arrest. 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.
