Levothyroxine Teva

Levothyroxine Sodium, the active ingredient in Levothyroxine Teva, is a thyroid hormone presented as a tablet for oral use. It replaces or supplements endogenous thyroid hormone, treating hypothyroidism and related thyroid hormone deficiencies in both adults and children. It is indicated for patients with primary or secondary hypothyroidism, as well as for thyroid hormone replacement after thyroidectomy.

GNH USA supplies Levothyroxine Teva as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides regulatory‑approved batches for global distribution.

Levothyroxine Teva is used to restore normal thyroid hormone levels in conditions affecting the hypothalamic‑pituitary‑thyroid axis. - Hypothyroidism: restores deficient thyroid hormone, normalizing metabolism and energy levels. - Post‑thyroidectomy hormone replacement: provides necessary thyroxine after surgical removal of the thyroid gland. - Congenital hypothyroidism: supplies thyroid hormone to infants born with insufficient gland function. - Goiter associated with hypothyroidism: reduces gland enlargement by correcting hormone deficiency.

Levothyroxine Teva may be associated with a range of adverse reactions, which are categorized by frequency and severity.

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

Serious or Rare Side Effects: - Cardiac arrhythmias - Angina pectoris - Hyperthyroidism symptoms (e.g., heat intolerance, anxiety) - Bone loss or fractures with long‑term overtreatment - Allergic reactions such as rash or angioedema - Severe chest pain

Before initiating Levothyroxine Teva, clinicians should consider several safety measures and monitoring requirements. - Dose adjustment: titrate based on serum TSH and free T4 levels. - Cardiovascular assessment: evaluate for ischemic heart disease before high‑dose therapy. - Pregnancy and lactation: use only if benefits outweigh potential risks; monitor thyroid function closely. - Elderly patients: start with lower doses to avoid overtreatment. - Drug interactions: review concomitant medications that may alter absorption or metabolism. - Store at ambient temperature: keep tablets in the original container, protect from moisture and light.

Levothyroxine Teva can interact with several medicines, affecting its absorption or hormonal activity.

Major Interactions (Avoid): - Calcium or iron supplements taken within 4 hours: markedly reduce levothyroxine absorption. - Proton pump inhibitors (e.g., omeprazole): decrease gastric acidity, impairing absorption. - Anticonvulsants such as phenytoin or carbamazepine: increase metabolic clearance of levothyroxine.

Moderate Interactions (Monitor Closely): - Cholestyramine or colestipol: bind the drug and lower its bioavailability. - Warfarin: levothyroxine may enhance anticoagulant effect, requiring INR monitoring. - Beta‑blockers: may mask symptoms of excess thyroid hormone.
