Composition

Each tablet contains:

• Levothyroxine Sodium 50 mcg

Indications

T4 Tablet is indicated for:

• Hypothyroidism (underactive thyroid)
• Congenital hypothyroidism
• Goiter due to thyroid hormone deficiency
• Thyroid hormone replacement therapy after thyroidectomy

Mechanism of Action

Levothyroxine is a synthetic thyroxine (T4) hormone that is converted in the body into the active form triiodothyronine (T3). It binds to thyroid hormone receptors in cells and regulates gene expression involved in metabolism, growth, and development. This helps normalize energy production, heart function, digestion, and temperature regulation.

Dosage & Administration

• Dosage is strictly individualized based on thyroid function tests (TSH, T3, T4 levels)
• Usually taken once daily on an empty stomach, preferably in the morning
• Swallow with water, at least 30–60 minutes before food
• Consistent timing is important for stable hormone levels
• Do not change dose without medical supervision

Precautions

• Use cautiously in patients with heart disease or hypertension
• Regular monitoring of thyroid hormone levels is required
• Overdose may cause symptoms of hyperthyroidism
• Inform physician about all ongoing medications (iron, calcium may reduce absorption)
• Not for weight loss use in normal thyroid function
