Lethyrox 50mcg Tab 100s (Levothyroxine) is a synthetic form of thyroxine (T4), a hormone naturally produced by the thyroid gland. It replaces missing or insufficient thyroid hormone, restoring normal metabolic function. The body converts T4 to triiodothyronine (T3), the active form of the hormone, which regulates numerous bodily processes, including metabolism, heart rate, and body temperature.
Store levothyroxine tablets at room temperature, away from moisture and heat. Keep it out of reach of children. Do not use if the medication shows signs of degradation or discoloration.
Dosage is individualized and determined by a physician based on individual needs and thyroid function tests.
It is typically taken once daily, usually in the morning on an empty stomach, at least 30-60 minutes before breakfast.
