Levothyroxine Sodium - Uses, Warnings,Precautions, Overdose and Brands

Levothyroxine Sodium

Levothyroxine Sodium is a type of thyroxine which enhances the basal metabolic rate (BMR) and the usage and assembly of glycogen stores. It also stimulates protein synthesis. It is likewise involved with usual metabolism, development, and growth. These impacts are controlled at the cellular level by the thyroxine metabolite, tri-iodothyronine.

This drug is an oral and injectable prescription thyroid hormone medication that is used to treat underactive thyroid (hypothyroidism) symptoms and other conditions. Having enough thyroid hormone is important for normal mental and physical development, especially in children. Enough thyroid hormone levels are important in maintaining normal mental health and physical activity, especially in children. If the thyroid gland is injured by radiation/medications or if it is removed by surgery, a low thyroid hormone level can occur naturally and it is a kind of drug that may be recommended by most doctors and specialists all over the world.
