Euthyroid 25 Tablet contains Thyroxine sodium 175 mcg, a synthetic form of the thyroid hormone used primarily to treat hypothyroidism, a condition where the thyroid gland does not produce enough hormones. Thyroxine plays a crucial role in regulating metabolism, energy generation, and overall growth and development. Euthyroid 25 helps restore normal thyroid hormone levels, thereby alleviating symptoms such as fatigue, weight gain, cold intolerance, constipation, and depression associated with an underactive thyroid. It is also prescribed for goiter and certain types of thyroid cancer as part of hormone replacement therapy. The medication should be taken orally, preferably on an empty stomach, to ensure optimal absorption. Dosage is individualized based on the patient’s thyroid hormone levels, age, weight, and clinical response, and regular monitoring through blood tests is essential to avoid under- or over-treatment. Overdosage may lead to symptoms of hyperthyroidism, including palpitations, nervousness, and weight loss. Patients with cardiovascular disorders, adrenal insufficiency, or sensitivity to thyroid hormones should use this medication cautiously under medical supervision. Euthyroid 25 Tablet is a vital therapy for maintaining normal metabolic function in individuals with thyroid hormone deficiency.
