Lethyrox 75 Tablet is a medicine used to treat an underactive thyroid (hypothyroidism), a condition in which the thyroid gland does not make enough thyroid hormone. It replaces the missing hormone, helping restore normal energy levels, metabolism and body temperature.
It contains thyroxine, a synthetic form of the natural thyroid hormone. It is usually taken on an empty stomach, 30 to 60 minutes before breakfast, swallowed whole with water. It is usually taken long term; continue taking it regularly even when you feel well, and do not stop it without medical advice.
Taking it consistently at the same time each day, and separating it from foods, supplements or medicines such as calcium or iron, helps ensure it is properly absorbed.
Before taking this medicine, tell your doctor about any heart problems or other medicines you take, and whether you are pregnant, as your dose may need adjusting. Attend regular blood tests so your thyroid levels can be checked. Tell your doctor about a fast or irregular heartbeat, chest pain, or unusual restlessness.
