Neo-Mercazole 20 mg contains Carbimazole, an antithyroid medication used to treat hyperthyroidism (overactive thyroid), including Graves’ disease. It works by reducing the production of thyroid hormones (T3 and T4) by inhibiting the enzyme thyroid peroxidase. This 20 mg strength is typically prescribed for moderate to severe cases or during initial treatment before surgery or radioactive iodine therapy.

• Helps manage symptoms like rapid heartbeat, tremors, and weight loss

• Used in the treatment of Graves’ disease and thyroid storm
