Details of Levothyroxine Salt (Generic Drug)
Levothyroxine is a replacement for a hormone normally produced by your thyroid gland to regulate the body's energy and metabolism. Levothyroxine is given when the thyroid does not produce enough of this hormone on its own. Levothyroxine treats hypothyroidism (low thyroid hormone). It is also used to treat or prevent goitre (enlarged thyroid gland), which can be caused by hormone imbalances, radiation treatment, surgery, or cancer. Since thyroid hormone occurs naturally in the body, almost anyone can take levothyroxine. To make sure levothyroxine is safe for you, tell your doctor if you have a thyroid disorder called thyrotoxicosis heart disease, coronary artery disease, or a history of blood clots diabetes (insulin or oral diabetes medication doses may need to be changed when you start taking levothyroxine) anaemia (lack of red blood cells) osteoporosis, or low bone mineral density problems with your pituitary gland any food or drug allergies an untreated or uncontrolled adrenal gland disorder or if you have recently had a heart attack, or are having any symptoms of a heart attack (chest pain or heavy feeling, pain spreading to the jaw or shoulder, nausea, sweating, general ill feeling).
Levothyroxine is used to treat an underactive thyroid (hypothyroidism). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery. Having enough thyroid hormone is important for maintaining normal mental and physical activity. In children, having enough thyroid hormone is important for normal mental and physical development. This medication is also used to treat other types of thyroid disorders (such as certain types of goitres, thyroid cancer). Levothyroxine should not be used to treat infertility unless it is caused by low thyroid hormone levels.
Common levothyroxine side effects may include fast or irregular heart rate fever, hot flashes, sweating sleep problems (insomnia) changes in your menstrual periods or vomiting, diarrhoea, appetite changes, weight changes.
