Levothyroxine Natrium Uni-Pharma

Levothyroxine Sodium, the active ingredient in Levothyroxine Natrium Uni-Pharma, is a thyroid hormone replacement presented as an oral tablet for systemic use. It restores normal thyroid hormone levels in patients with hypothyroidism, after thyroidectomy, or with goitre. Levothyroxine Natrium Uni-Pharma is supplied as a licensed, GDP‑compliant pharmaceutical product.

GNH USA supplies Levothyroxine Natrium Uni-Pharma as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Levothyroxine Sodium is used to treat disorders of thyroid hormone deficiency and related metabolic conditions. - Hypothyroidism: normalises low thyroid hormone levels and alleviates fatigue, weight gain and cold intolerance. - Post‑thyroidectomy replacement: provides the missing thyroxine after surgical removal of the thyroid gland. - Goitre: reduces gland enlargement by supplying adequate hormone feedback.

Levothyroxine Sodium may cause a range of adverse reactions, most of which are dose‑related.

Common Side Effects: - Headache: mild to moderate discomfort often reported during dose adjustments. - Insomnia: difficulty falling or staying asleep, especially with higher doses. - Palpitations: sensation of rapid or irregular heartbeat. - Heat intolerance: increased sensitivity to warm environments. - Tremor: fine shaking of hands or limbs. - Weight loss: unintended reduction in body weight.

Serious or Rare Side Effects: - Cardiac arrhythmia: irregular heart rhythm that may require medical attention. - Angina pectoris: chest pain due to reduced coronary blood flow. - Myocardial infarction: rare but possible in susceptible individuals. - Severe bone loss: accelerated osteoporosis with long‑term overtreatment. - Anaphylaxis: rare allergic reaction with rash, swelling, or breathing difficulty. - Acute adrenal crisis: precipitated in patients with untreated adrenal insufficiency.

Levothyroxine Sodium requires careful clinical monitoring to avoid over‑ or under‑replacement. - Dose titration: adjust gradually, especially in elderly or cardiac patients. - Thyroid function monitoring: check TSH and free T4 levels regularly after dose changes. - Cardiovascular risk: use caution in patients with ischemic heart disease or arrhythmias. - Adrenal insufficiency: ensure adequate glucocorticoid replacement before initiating levothyroxine. - Pregnancy and lactation: discuss risks with a healthcare professional; dosing may need adjustment. - Store at ambient temperature: keep below 25 °C, in the original container, protected from moisture and light.

Levothyroxine Sodium can interact with several medicines, altering its absorption or pharmacodynamic effect.

Major Interactions (Avoid): - Calcium supplements: bind levothyroxine in the gut, reducing absorption. - Iron salts: significantly decrease oral bioavailability when taken concurrently. - Antacids containing aluminum or magnesium: impair absorption if taken within 4 hours. - Cholestyramine and other bile‑acid sequestrants: lower systemic exposure. - Sucralfate: forms insoluble complexes, decreasing effectiveness.

Moderate Interactions (Monitor Closely): - Warfarin: levothyroxine may enhance anticoagulant effect, requiring INR monitoring. - Oral contraceptives: may increase levothyroxine binding proteins, altering dose needs. - Amiodarone: affects thyroid hormone metabolism, necessitating closer TSH checks. - Beta‑blockers: may mask symptoms of thyrotoxicosis. - Diabetes medications: thyroid status influences glucose control, requiring dose adjustments.
