Levothyroxine sodium, the active ingredient in L-Thyroxin 100 1 A Pharma, is a thyroid hormone presented as a 100 µg oral tablet for oral use. It replaces deficient thyroid hormone and is indicated for the treatment of hypothyroidism and goiter in patients requiring hormone replacement.

GNH USA supplies L-Thyroxin 100 1 A Pharma as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides reliable global distribution.

Levothyroxine sodium is a synthetic thyroid hormone that acts on the hypothalamic‑pituitary‑thyroid axis to restore normal hormone levels. - Hypothyroidism: normalizes thyroid hormone concentrations, relieving fatigue, weight gain and cold intolerance. - Goiter: reduces thyroid gland enlargement by correcting hormone deficiency. - Post‑thyroidectomy thyroid hormone replacement: maintains metabolic function after surgical removal of the thyroid.

Levothyroxine sodium may cause adverse reactions, ranging from mild to severe, that should be monitored during therapy.

Common Side Effects: - Headache: mild to moderate intensity. - Insomnia: difficulty falling or staying asleep. - Nervousness or tremor: mild increase in nervous system activity. - Sweating: increased perspiration without exertion.

Serious or Rare Side Effects: - Chest pain or palpitations: possible sign of cardiac arrhythmia. - Severe allergic reaction: rash, itching, swelling, or anaphylaxis. - Hyperthyroidism symptoms: rapid weight loss, heat intolerance, or bone loss.

When prescribing levothyroxine sodium, clinicians should consider several precautionary measures to ensure safe and effective therapy. - Dose adjustment: monitor TSH and free T4 levels regularly and adjust dose accordingly. - Cardiovascular disease: initiate therapy at a low dose and titrate slowly in patients with coronary artery disease. - Elderly patients: consider reduced starting dose due to altered metabolism. - Pregnancy: use only if the potential benefit justifies the potential risk to the fetus. - Drug interactions: review concomitant medications that may affect absorption or hormone levels. - Store at room temperature: keep in the original container, protect from moisture and light.

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

Major Interactions (Avoid): - Antacids containing aluminum or magnesium: significantly reduce levothyroxine absorption. - Calcium supplements: bind the drug in the gut and decrease its bioavailability. - Iron salts: impair absorption when taken concurrently.

Moderate Interactions (Monitor Closely): - Warfarin: levothyroxine may enhance anticoagulant effect, requiring INR monitoring. - Amiodarone: can affect thyroid hormone synthesis and conversion, necessitating thyroid function tests. - Beta‑blockers: may mask symptoms of excess thyroid hormone, requiring careful clinical assessment.
