L-Thyroxin 112 1 A Pharma

Levothyroxine Sodium, the active ingredient in L-Thyroxin 112 1 A Pharma, is a thyroid hormone presented as a tablet for oral use. It replaces deficient thyroid hormone in patients with hypothyroidism, supporting normal metabolic activity.

GNH USA supplies L-Thyroxin 112 1 A Pharma as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to global quality standards and provides reliable sourcing for regulated markets. With a focus on product integrity and timely delivery, GNH USA supports the therapeutic needs of patients across multiple continents.

L-Thyroxin 112 is used to treat conditions related to thyroid hormone deficiency. - Hypothyroidism: restores normal metabolic rate by supplying synthetic T4 to replace insufficient endogenous hormone. - Post‑thyroidectomy hormone replacement: provides necessary thyroid hormone after surgical removal of the thyroid gland. - Congenital hypothyroidism: supplies thyroid hormone to infants born with inadequate thyroid function, supporting growth and development.

Levothyroxine sodium may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Headache - Fatigue - Nausea - Weight loss - Palpitations - Insomnia

Serious or Rare Side Effects: - Cardiac arrhythmia - Angina or myocardial infarction - Severe allergic reaction (anaphylaxis) - Bone loss (osteoporosis) with long‑term high dose - Hyperthyroidism symptoms such as tachycardia and tremor - Acute hepatic dysfunction (very rare)

When prescribing levothyroxine, clinicians should consider several safety measures to ensure optimal therapy. - Dose titration: adjust the dose based on thyroid function tests and clinical response. - Cardiovascular monitoring: assess for angina or arrhythmias, especially in elderly patients. - Drug absorption: separate administration from calcium, iron, or antacid products by at least 4 hours. - Pregnancy and lactation: use only if benefits outweigh potential risks and monitor maternal thyroid status closely. - Thyroid function monitoring: check serum TSH and free T4 levels 6–8 weeks after dose changes. - Store at ambient temperature: keep tablets in the original container, protect from moisture and light.

Levothyroxine interacts with several medicines that can alter its absorption or effect.

Major Interactions (Avoid): - Calcium carbonate or calcium supplements: markedly reduce levothyroxine absorption. - Iron salts (ferrous sulfate): significantly decrease absorption when taken concurrently. - Antacids containing aluminum or magnesium: impair absorption. - Rifampin and other enzyme inducers: increase metabolism, reducing therapeutic levels. - Amiodarone: may cause thyroid dysfunction, requiring close monitoring.

Moderate Interactions (Monitor Closely): - Warfarin: levothyroxine may enhance anticoagulant effect, monitor INR. - Antidepressants (SSRIs): may affect thyroid hormone levels, monitor clinical response. - Cholesterol‑lowering agents (e.g., cholestyramine): can bind levothyroxine, reduce efficacy. - Oral contraceptives: may increase levothyroxine binding, dose adjustment may be needed.
