Thirid 12.5 is a brand of medication containing thyroxine, a synthetic form of the thyroid hormone thyroxine (T4). Thyroxine is crucial for regulating metabolism, energy production, and growth and development in the body. Thirid 12.5 is specifically formulated to provide a dosage of 12.5 micrograms of thyroxine per tablet. This dosage is often prescribed to manage conditions such as hypothyroidism, where the thyroid gland does not produce enough thyroid hormone, or to suppress the growth of thyroid nodules or goiter. Thirid 12.5 works by replacing or supplementing the natural thyroxine levels in the body, restoring them to normal levels. It is typically taken orally, once daily, on an empty stomach, preferably in the morning, to ensure optimal absorption. As with any medication, it is important to follow the dosage instructions provided by a healthcare professional and to report any adverse reactions or concerns. Thirid 12.5 can effectively alleviate symptoms associated with thyroid hormone deficiency when used as directed under medical supervision.
