LEVOTHYROXINE - SYNTHROID ® COMMON USES: Levothyroxine, a thyroid hormone, is used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. Without this hormone, the body cannot function properly, resulting in poor growth, slow speech, lack of energy, weight gain, hair loss, dry thick skin, and increased sensitivity to cold. When taken correctly, levothyroxine reverses these symptoms. Levothyroxine is also used to treat congenital hypothyroidism (cretinism) and goiter (enlarged thyroid gland). This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. Levothyroxine comes as a tablet to take by mouth. It usually is taken once a day on an empty stomach, 1/2 to 1 hour before breakfast . Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take levothyroxine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. The tablets may get stuck in your throat or cause choking or gagging; therefore, the tablet should be taken with a full glass of water. If you are giving levothyroxine to an infant or child who cannot swallow the tablet, crush the tablet and mix it in 1 to 2 teaspoons of plain water. Give this mixture by spoon or dropper right away. Do not store this mixture. Only mix the crushed tablets with water. Do not mix with food or soybean infant formula. Your doctor will probably start you on a low dose of levothyroxine and gradually increase your dose. Levothyroxine controls hypothyroidism, but does not cure it. It may several weeks before you notice a change in your symptoms. Continue to take levothyroxine even if you feel well. Do not stop taking levothyroxine without talking to your doctor.
