Tirosint (levothyroxine sodium) is a replacement for a hormone that is normally produced by your thyroid gland to regulate the body's energy and metabolism used to treat hypothyroidism (low thyroid hormone). Tirosint is also used to treat or prevent goiter (enlarged thyroid gland), which can be caused by hormone imbalances, radiation treatment, surgery, or cancer. Tirosint is available in generic form. Common side effects of Tirosint include hair loss, changes in menstrual cycle, and appetite or weight changes. Tell your doctor if you have a serious side effect of Tirosint including headache, sleep problems (insomnia), nervous feeling, irritability, fever, hot flashes, sweating, pounding heartbeats, or fluttering in your chest.

Tirosint is taken in a single daily dose, ranging in strengths of 13 mcg to 150 mcg, preferably � to 1 hour before breakfast. Tirosint may interact with medications such as calcium carbonate (Caltrate, Citracal, Oystercal, and others), iron supplements, sucralfate (Carafate), sodium polystyrene sulfonate (Kayexalate, Kionex, and others), antacids containing aluminum (Maalox, Mylanta, Tums, and others), and cholesterol-lowering drugs cholestyramine (Questran) and colestipol (Colestid). Tell your doctor all medications or supplements you take. If you are pregnant or become pregnant, tell your doctor because your dose may need adjustment. This medication passes into breast milk but is unlikely to harm a nursing infant. Consult your doctor before breastfeeding.

Pseudotumor cerebri and slipped capital femoral epiphysis have been reported in children receiving levothyroxine therapy. Overtreatment may result in craniosynostosis in infants and premature closure of the epiphyses in children with resultant compromised adult height. Seizures have been reported rarely with the institution of levothyroxine therapy.
