UPA T3 25mcg (Liothyronine Sodium)

UPA T3 25mcg is an oral synthetic thyroid hormone containing Liothyronine Sodium, a pharmaceutical form of triiodothyronine (T3). Each tablet contains a stated 25mcg of Liothyronine Sodium, supplied in a pack of 50 tablets.

T3 is one of the body's primary thyroid hormones and plays an essential role in metabolic regulation, energy production, body temperature and normal cellular function.

Unlike thyroxine (T4), which must be converted into T3 to produce much of its biological activity, Liothyronine provides the active thyroid hormone directly.

What UPA T3 25mcg Is Used For

Liothyronine is used medically for selected thyroid conditions and is involved in several important metabolic processes.

• Hypothyroidism Treatment: Prescription Liothyronine may be used for certain patients with insufficient thyroid hormone production.
• Thyroid Hormone Replacement: Provides synthetic T3 to support normal thyroid hormone activity.
• Metabolic Regulation: Influences the rate at which cells utilise energy.
• Energy Production: Supports cellular processes involved in energy metabolism.
• Body Temperature Regulation: Helps maintain normal thermogenesis and temperature control.
• Carbohydrate and Fat Metabolism: Influences how the body processes glucose and fatty acids.
• Thyroid Function Management: Used in selected medical situations requiring specific thyroid hormone treatment.

How UPA T3 25mcg Works

Liothyronine Sodium provides synthetic triiodothyronine (T3), which interacts with thyroid hormone receptors throughout the body.

• Thyroid Receptor Activation: Binds to thyroid hormone receptors, influencing gene expression and cellular activity.
• Metabolic Activity: Regulates biological processes involved in energy expenditure.
• Cellular Energy Production: Influences mitochondrial function and cellular metabolism.
• Thermogenesis: Contributes to normal body temperature regulation and heat production.
• Fat and Glucose Metabolism: Affects the breakdown and utilisation of carbohydrates and fats.
• Cardiovascular Activity: Influences heart rate, cardiac output and cardiovascular function.
• Hormonal Feedback: External T3 can suppress thyroid-stimulating hormone (TSH) production.

Because T3 is biologically active, excessive exposure can produce symptoms resembling an overactive thyroid.

Possible Side Effects

Liothyronine may cause adverse effects associated with excessive thyroid hormone activity, particularly when thyroid hormone levels become elevated.

Common or Recognised Side Effects:

• Increased heart rate or palpitations.
• Excessive sweating.
• Heat intolerance.
• Nervousness, anxiety or irritability.
• Tremors or shaking.
• Difficulty sleeping.
• Headaches.
• Increased appetite.
• Diarrhoea or gastrointestinal discomfort.
