Levothyroxine Sodium Tablets are a prescription medicine that belongs to the class of thyroid hormone replacement drugs. They are used to treat conditions where the body does not produce enough thyroid hormone.

Here are the key details:

• Main Use:

  • Treats hypothyroidism (underactive thyroid), where the thyroid gland does not produce enough hormones.

  • Used in certain cases of goiter (enlarged thyroid) or after thyroid surgery to replace missing thyroid hormone.

• How It Works: Levothyroxine is a synthetic form of the natural thyroid hormone T4. It replaces or supplements the hormone in the body, helping regulate metabolism, energy, and growth.

• Administration: Taken orally, usually once daily on an empty stomach, at least 30–60 minutes before food. Consistency in timing is important for maintaining stable hormone levels.

• Common Side Effects: Usually well-tolerated when dosed correctly. Mild side effects may include headache, mild sweating, or temporary hair loss in children.

• Serious Concerns: Overdose or excessive dosing may cause symptoms of hyperthyroidism, such as rapid heartbeat, palpitations, anxiety, insomnia, weight loss, or heat intolerance.

• Precautions:

  • Dose adjustments are required in patients with heart disease or severe kidney problems.

  • Regular monitoring of thyroid function tests is recommended to ensure proper dosing.

  • Inform the doctor about all other medications or supplements, especially calcium or iron, as they can interfere with absorption.

• Storage: Store at room temperature, away from moisture, heat, and direct sunlight.
