Levothyroxine Sodium is used for the treatment of an underactive thyroid or called hypothyroidism.

In children, having enough thyroid hormone is important for physical and normal mental development.

How doesLevothyroxine Sodium work?

LevothyroxineSodium is similar to natural hormone thyroxine which is normally produced bythe thyroid gland. 

Thethyroid gland usually creates and releases two thyroid hormones which are thethyroxine (T4) and tri-iodothyronine (T3). T3 is the more active thyroidhormone and T4 is converted into T3 in several parts of the body. Thesehormones are accountable for preserving a regular rate of metabolism in thebody. If the thyroid gland is incapable to create normal quantities ofthyroxine, the levels of both thyroid hormones in the blood drop. This is knownas hypothyroidism. It results in a reduced rate of metabolism which leads tosymptoms such as tiredness, weight gain, and intolerance to cold.

Levothyroxine Sodium tablets work by replacing the thyroxine that would normally be produced naturally by your thyroid gland. This returns levels of T3 and T4 to normal.
