Methimazole 10mg – A Safe and Effective Option for Hyperthyroid Patients

Feb 18, 2025

Introduction

METHIMZOLE 10 is a widely used medication containing Methimazole (10mg), primarily prescribed for the treatment of hyperthyroidism. It is an antithyroid drug that plays a crucial role in managing Graves' disease and other conditions related to overactive thyroid glands. By inhibiting thyroid hormone synthesis, METHIMZOLE 10 helps in controlling symptoms such as weight loss, rapid heartbeat, excessive sweating, and nervousness.

Key Ingredients

The active ingredient in METHIMZOLE 10 is Methimazole (10mg), a thiourea derivative that effectively reduces the production of thyroid hormones. It works by blocking the enzyme thyroid peroxidase, which is necessary for hormone synthesis.

Uses of METHIMZOLE 10

1. Treatment of Hyperthyroidism

METHIMZOLE 10 is commonly prescribed to reduce excessive thyroid hormone levels and alleviate symptoms of hyperthyroidism.

2. Management of Graves' Disease

This medication is effective in controlling Graves' disease, an autoimmune disorder that leads to an overactive thyroid.

3. Pre-Surgical Preparation

In some cases, METHIMZOLE 10 is used before thyroid surgery to stabilize hormone levels and minimize complications.

4. Preparation for Radioactive Iodine Therapy

It is often prescribed before or after radioactive iodine treatment to prevent a sudden surge in thyroid hormones.

How Does METHIMZOLE 10 Work?

Methimazole (10mg) works by inhibiting the thyroid peroxidase enzyme, which is responsible for the synthesis of thyroxine (T4) and triiodothyronine (T3). By blocking this enzyme, METHIMZOLE 10 reduces the levels of circulating thyroid hormones, helping to maintain a balanced thyroid function.

  • The initial dose for adults with mild hyperthyroidism is typically 15mg per day (1.5 tablets of METHIMZOLE 10).

  • For moderate hyperthyroidism, the dosage is 30-40mg per day, divided into multiple doses.

  • In severe cases, up to 60mg per day may be required.

  • Maintenance dose is usually 5-15mg per day.

Administration

  • METHIMZOLE 10 should be taken orally with water.

  • It can be taken with or without food, but consistency in administration is recommended.
