Product Profile: T-3 25mcg Tablets (Liothyronine Sodium) T-3 (Liothyronine Sodium) 25mcg is a potent synthetic form of the thyroid hormone triiodothyronine (T3). It is primarily used in clinical settings to treat hypothyroidism, myxedema coma, and in specific diagnostic testing protocols. Unlike levothyroxine (T4), which is a pro-hormone, T-3 provides an immediate, active hormonal effect on metabolic processes. 1. Clinical Indications & Usage Hypothyroidism: Indicated as replacement therapy for patients who have an inadequate response to T4-only therapy or require a rapid metabolic increase. T3 Suppression Test: Used in diagnostic procedures to differentiate various forms of hyperthyroidism. Mechanism of Action: Metabolic Regulation: T3 is the most potent thyroid hormone. It enters the cell nucleus and binds to thyroid hormone receptors, stimulating the transcription of DNA and the synthesis of proteins, which increases the basal metabolic rate. Direct Action: Because it is the active form of thyroid hormone, T-3 exerts its effects immediately upon absorption, without needing to be converted from T4 by peripheral tissues. 2. Administration and Dosing Regimen: Must be strictly followed according to a physician's prescription. Due to its rapid onset and short half-life, dosing is typically split throughout the day to maintain steady serum concentrations. Professional Requirement: Requires clinical supervision and regular monitoring of serum TSH, Free T3, and Free T4 levels to prevent thyrotoxicosis (over-medication). ⚠️ Safety, Side Effects, and Monitoring Contraindications: Contraindicated in patients with untreated thyrotoxicosis, uncorrected adrenal insufficiency, or hypersensitivity to any component of the tablet. Use with extreme caution in patients with pre-existing cardiovascular disease. Critical Warnings: Cardiovascular Stress: Can cause tachycardia, palpitations, arrhythmias, or exacerbate symptoms of angina/ischemic heart disease due to increased metabolic demand on the heart. Overdose Risk: Symptoms of overdose mirror hyperthyroidism: heat intolerance, excessive sweating, weight loss, tremor, nervousness, and insomnia. 📦 Storage, Stability & Commercial Packaging Storage: Store at controlled room temperature (20°C to 25°C / 68°F to 77°F). Protection: Keep in original blister packaging or amber glass bottles to protect from light and moisture, which can degrade hormonal stability. PRESCRIPTION MEDICINE IS: YES.
