Levotiroxina Sanofi

Levothyroxine Sodium, the active ingredient in Levotiroxina Sanofi, is a synthetic thyroid hormone presented as an oral tablet for oral use. It treats hypothyroidism and related thyroid hormone deficiencies in adults and children.

GNH USA supplies Levotiroxina Sanofi as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide.

Levotiroxina Sanofi, a synthetic thyroid hormone, acts on the hypothalamic‑pituitary‑thyroid axis to restore normal metabolism.

- Hypothyroidism: restores normal thyroid hormone levels, alleviating fatigue, weight gain and cold intolerance. - Post‑thyroidectomy hormone deficiency: provides necessary thyroxine replacement after surgical removal of the thyroid gland. - Goiter: suppresses thyroid‑stimulating hormone to reduce gland enlargement. - Thyroid cancer suppression therapy: helps maintain low TSH levels to limit tumor stimulation.

Levotiroxina Sanofi may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects: - Headache: mild to moderate headache. - Palpitations: sensation of rapid or irregular heartbeat. - Tremor: fine shaking of the hands. - Insomnia: difficulty falling or staying asleep.

Serious or Rare Side Effects: - Cardiac arrhythmia: potentially life‑threatening irregular heart rhythm. - Angina pectoris: chest pain due to reduced heart blood flow. - Osteoporosis: decreased bone density with long‑term overtreatment. - Allergic reaction: rash, itching, swelling, or anaphylaxis.

Before prescribing Levotiroxina Sanofi, clinicians should consider several safety precautions.

- Dose adjustment: individualize dose based on age, weight, cardiac status and laboratory thyroid function tests. - Cardiovascular disease: monitor closely in patients with coronary artery disease or arrhythmias. - Pregnancy and lactation: use only if benefits outweigh potential risks; consult obstetric specialist. - Elderly patients: start with lower dose and titrate slowly to avoid overtreatment. - Drug interactions: review concomitant medications that may affect levothyroxine absorption or metabolism. - Store at ambient temperature: keep below 25°C in the original container, protect from moisture and light.

Levotiroxina Sanofi can interact with several medicines, altering its effectiveness or safety.

Major Interactions (Avoid): - Calcium or iron supplements: significantly reduce levothyroxine absorption; separate dosing by at least 4 hours. - Proton pump inhibitors (e.g., omeprazole): may decrease absorption; monitor thyroid function. - Anticonvulsants (e.g., phenytoin, carbamazepine): increase metabolism leading to reduced efficacy.

Moderate Interactions (Monitor Closely): - Warfarin: levothyroxine may enhance anticoagulant effect; monitor INR. - Beta‑blockers: may mask symptoms of thyrotoxicosis; observe cardiovascular response. - Cholesterol‑lowering agents (e.g., cholestyramine): can bind levothyroxine and lower its bioavailability.
