Liothyronine Sodium Tablet 25 mcg

Liothyronine Sodium Tablet 25 mcg – Complete Product Description

Liothyronine Sodium Tablet 25 mcg is a prescription thyroid hormone medication used for the treatment of hypothyroidism and other thyroid hormone deficiency disorders. It contains liothyronine sodium, a synthetic form of triiodothyronine (T3), which is the biologically active thyroid hormone responsible for regulating metabolism, energy production, and overall cellular function.

Thyroid hormones are essential for maintaining normal body processes such as heart rate, body temperature, digestion, mental alertness, and energy levels. When the thyroid gland does not produce enough hormones, it can lead to symptoms like chronic fatigue, weight gain, depression, cold sensitivity, slowed metabolism, and cognitive difficulties. Liothyronine Sodium 25 mcg helps restore adequate hormone levels, allowing the body to function normally.

Unlike levothyroxine (T4), which must be converted into T3 inside the body, liothyronine provides direct T3 hormone, making it faster acting and especially useful for patients who have impaired T4-to-T3 conversion.

Composition

• Active Ingredient: Liothyronine Sodium 25 mcg

• Drug Class: Thyroid Hormone (Synthetic T3)

Liothyronine is structurally identical to the natural T3 hormone produced by the thyroid gland.

Therapeutic Uses of Liothyronine Sodium 25 mcg

Liothyronine Sodium Tablet 25 mcg is prescribed for:

• Primary hypothyroidism

• Secondary or tertiary hypothyroidism

• Thyroid hormone replacement therapy

• Myxedema coma (as part of emergency treatment protocols)

• Thyroid suppression tests under medical supervision

In some cases, it may be used in combination with levothyroxine (T4) for patients who continue to experience hypothyroid symptoms despite normal thyroid test results.

How Liothyronine Sodium Works

Liothyronine Sodium Tablet 25 mcg works by directly supplying the body with T3 hormone, which is the active form of thyroid hormone at the cellular level. T3 binds to thyroid hormone receptors in cells and regulates:

• Metabolic rate

• Energy production

• Protein synthesis

• Heart and nervous system function

• Growth and development

Because it does not require conversion from T4, Liothyronine acts more rapidly than levothyroxine, providing quicker symptom relief in appropriate patients.

Dosage and Administration

• Dosage is individualized based on age, body weight, medical condition, and thyroid hormone levels

• Typically taken once daily, or in divided doses as prescribed

• Tablets should be taken consistently at the same time each day

• Can be taken with or without food, but consistency is important

⚠️ Do not change the dose or stop the medication abruptly without medical advice, as improper use may lead to serious cardiovascular or metabolic complications.

Benefits of Liothyronine Sodium 25 mcg

• Provides direct, active thyroid hormone (T3)

• Faster onset of action compared to T4-only therapy

• Helps improve energy levels and mental clarity

• Supports metabolic balance and body temperature regulation

• Useful for patients with poor T4-to-T3 conversion
