Letrox

Levothyroxine sodium hydrate, the active ingredient in Letrox, is a thyroid hormone presented as an oral tablet for oral use. It replaces deficient endogenous thyroid hormone and is used to treat hypothyroidism, support hormone replacement after thyroidectomy, and manage goiter.

GNH USA supplies Letrox as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides reliable sourcing for endocrine therapy needs across multiple regions, including Europe, Asia and Africa.

Letrox (levothyroxine sodium hydrate) is used to restore thyroid hormone levels in disorders of thyroid hormone deficiency.

- Hypothyroidism: restores normal metabolic rate and alleviates symptoms of low thyroid function. - Post‑thyroidectomy hormone replacement: provides the missing thyroid hormone after surgical removal of the thyroid gland. - Goiter: helps reduce thyroid gland enlargement by normalising hormone feedback mechanisms.

Adverse reactions may occur with levothyroxine therapy.

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

Serious or Rare Side Effects: - Cardiac arrhythmia - Angina pectoris - Severe allergic reaction (anaphylaxis)

When prescribing levothyroxine, clinicians should consider several safety measures.

- Dose adjustment: required in elderly patients or those with cardiac disease. - Monitoring: periodic assessment of serum TSH and free T4 levels is essential. - Contraindications: avoid use in untreated adrenal insufficiency. - Pregnancy: prescribe only if clearly needed after risk‑benefit evaluation. - Drug interactions: review concomitant medications that may affect absorption or hormone levels. - Store at ambient temperature: keep in the original container, protect from moisture and light.

Levothyroxine may interact with several medicines, influencing its absorption or activity.

Major Interactions (Avoid): - Antacids containing aluminum or magnesium - Calcium supplements - Iron supplements - Warfarin (may increase INR) - Amiodarone (alters thyroid hormone metabolism)

Moderate Interactions (Monitor Closely): - Beta‑blockers (can mask symptoms of hyperthyroidism) - Statins (potential impact on thyroid hormone metabolism)
