Methimercazole 5 Tablet

Description

Methimercazole 5 Tablet is a prescription medication containing Methimazole 5 mg, a well-established antithyroid agent used to manage hyperthyroidism and related thyroid disorders. Manufactured by Abbott, this lower-strength tablet is ideal for patients requiring gradual dose titration or maintenance therapy. Methimazole helps restore normal thyroid function by reducing excessive production of thyroid hormones, thereby alleviating symptoms associated with an overactive thyroid.

Methimazole belongs to the thionamide class of drugs. It works by inhibiting thyroid peroxidase, an enzyme essential for the synthesis of T3 (triiodothyronine) and T4 (thyroxine), the key thyroid hormones responsible for regulating metabolism. By controlling hormone levels, Methimercazole 5 mg aids in stabilizing metabolic processes and improving overall patient well-being.

Therapeutic Uses:

1. Graves’ Disease: Helps manage autoimmune hyperthyroidism by controlling excessive hormone production.

2. Toxic Multinodular Goiter: Reduces overproduction of thyroid hormones in nodular thyroid conditions.

3. Pre-Surgical Preparation: Stabilizes hormone levels before thyroidectomy or radioactive iodine therapy.

4. Maintenance Therapy: Useful in long-term management or dose titration for patients requiring lower-strength treatment.

Mechanism of Action:
Methimazole inhibits thyroid peroxidase, the enzyme responsible for the iodination of tyrosine residues in thyroglobulin, which is essential for the production of T3 and T4. By limiting hormone synthesis, Methimercazole 5 mg helps normalize thyroid hormone levels, reducing hyperthyroid symptoms such as palpitations, weight loss, anxiety, tremors, and heat intolerance.

Dosage & Administration:

• Take Methimercazole 5 Tablet exactly as prescribed by a healthcare professional.

• Administer orally, with or without food, and swallow with water.

• Dosage may vary depending on severity of hyperthyroidism, patient response, and thyroid hormone levels.

• Regular monitoring of thyroid function tests (T3, T4, TSH) is recommended to ensure effective dose adjustments.

• Do not stop the medication abruptly without consulting a doctor, as symptoms may recur.

Safety Information & Precautions:

• Prescription-only; use under medical supervision.
