Euthycin 50mcg Tablet 100s - Levothyroxine | Incepta Pharmaceuticals

What is Euthycin 50mcg Tablet?

Euthycin 50mcg Tablet is a synthetic thyroid hormone replacement manufactured by Incepta Pharmaceuticals Ltd., containing Levothyroxine Sodium. It is used to treat hypothyroidism (underactive thyroid) and certain other thyroid conditions.

Generic Name and Composition

Each Euthycin Tablet contains Levothyroxine Sodium 50 mcg.

Indications

• Replacement therapy in primary, secondary, or tertiary hypothyroidism
• Pituitary TSH suppression in the management of thyroid nodules, multinodular goiter, and as adjunctive therapy in thyroid cancer
• Management of congenital hypothyroidism
• Subclinical hypothyroidism, as advised by a physician

How It Works - Mechanism of Action

Levothyroxine is a synthetic form of thyroxine (T4), which is converted peripherally to triiodothyronine (T3), the more biologically active form. It binds to thyroid hormone receptors in the nucleus, regulating gene transcription and exerting its metabolic effects on growth, development, and overall metabolism, effectively replacing endogenous thyroid hormone in deficient patients.

Dosage and Administration

• Dosage is individualized based on age, body weight, cardiac status, and severity/duration of hypothyroidism, and TSH/T4 levels
• Usual starting dose in adults: 25-50 mcg once daily, with gradual titration based on periodic thyroid function tests
• Take on an empty stomach, preferably 30-60 minutes before breakfast, with a full glass of water
• Maintain consistent timing of intake daily for stable hormone levels
• Avoid taking simultaneously with calcium, iron supplements, or antacids - separate by at least 4 hours
• Dose adjustments should only be made under physician supervision, typically with thyroid function tests every 6-8 weeks initially

Side Effects

Common: Usually well tolerated at correct replacement doses; symptoms below typically relate to over-replacement

Uncommon: Palpitations, tremor, headache, insomnia, anxiety, excessive sweating, weight loss, heat intolerance (signs of overdose/hyperthyroidism)

Rare: Cardiac arrhythmias, angina, allergic skin reactions, reduced bone mineral density with long-term excessive dosing

Drug Interactions

Calcium and Iron Supplements/Antacids: Reduce absorption of levothyroxine - separate dosing by at least 4 hours

Oral Anticoagulants (e.g., warfarin): Levothyroxine may potentiate anticoagulant effect - monitor INR closely

Antidiabetic Agents and Insulin: May alter blood glucose control - dose adjustment of antidiabetic therapy may be needed

Cholestyramine/Colestipol: May reduce levothyroxine absorption - separate dosing

Enzyme Inducers (e.g., rifampin, phenytoin, carbamazepine): May increase levothyroxine metabolism, requiring dose adjustment

Estrogen/Oral Contraceptives: May increase thyroid-binding globulin, potentially requiring levothyroxine dose adjustment

Contraindications

• Untreated thyrotoxicosis
• Untreated adrenal insufficiency
• Acute myocardial infarction
• Known hypersensitivity to levothyroxine or any excipient

Pregnancy and Lactation

Levothyroxine is considered safe and necessary during pregnancy for women with hypothyroidism, as untreated maternal hypothyroidism can affect fetal development. Dose requirements often increase during pregnancy. It is also considered compatible with breastfeeding. Close monitoring of thyroid function by a physician is essential throughout pregnancy and lactation.

Precautions and Warnings

• Use with caution in patients with cardiovascular disease, as levothyroxine can increase cardiac workload
• Use with caution in elderly patients and those with longstanding untreated hypothyroidism - start at lower doses
• Monitor closely in patients with adrenal insufficiency; corticosteroid replacement should be addressed first
• Periodic monitoring of thyroid function tests (TSH, T4) is essential to avoid over- or under-treatment
• Not intended for weight loss in euthyroid individuals - inappropriate use can cause serious adverse effects

Overdose

Overdose may cause symptoms of hyperthyroidism such as palpitations, chest pain, excessive sweating, tremor, headache, nervousness, and in severe cases, arrhythmias or heart failure. Seek immediate medical attention. Management is generally supportive, with discontinuation or dose reduction and monitoring of cardiac status as directed by a physician.

Storage Instructions

• Store below 25°C in a cool, dry place
• Protect from light and moisture
• Keep in original packaging
• Keep out of reach of children
