L-Thyroxin 25 1 A Pharma

Levothyroxine Sodium, the active ingredient in L-Thyroxin 25 1 A Pharma, is a thyroid hormone replacement presented as a 25 µg tablet for oral use. It treats hypothyroidism and related thyroid hormone deficiencies in adults and children.

GNH USA supplies L-Thyroxin 25 1 A Pharma as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Levothyroxine is used to restore normal thyroid hormone activity in conditions affecting the thyroid gland.

- Hypothyroidism: restores normal hormone levels, relieving fatigue, weight gain, and cold intolerance. - Goiter: reduces TSH stimulation, helping shrink an enlarged thyroid. - Post‑thyroidectomy or radioactive iodine therapy: provides necessary thyroxine to maintain metabolic function.

Levothyroxine may cause a range of adverse reactions, most of which are dose‑related and reversible.

Common Side Effects: - Headache: mild to moderate discomfort. - Insomnia: difficulty falling or staying asleep. - Palpitations: sensation of rapid or irregular heartbeat. - Weight loss: unintended reduction in body weight. - Sweating: increased perspiration. - Tremor: fine shaking of hands or limbs.

Serious or Rare Side Effects: - Allergic reaction: rash, itching, or swelling. - Angioedema: rapid swelling of face, lips, or throat. - Chest pain: possible sign of cardiac strain. - Arrhythmia: abnormal heart rhythm. - Osteoporosis: reduced bone density with long‑term excess. - Severe hyperthyroidism: symptoms of over‑replacement such as heat intolerance and anxiety.

Levothyroxine requires careful monitoring and individualized dosing.

- Dose titration: adjust based on serum TSH and clinical response. - Cardiovascular disease: monitor for tachycardia, angina, or arrhythmias. - Pregnancy: use only when benefits outweigh potential risks. - Elderly patients: initiate therapy at lower doses to avoid cardiac stress. - Drug interactions: review concomitant medications for absorption or metabolic effects. - Store at ambient temperature: keep below 25 °C, in original packaging, protected from moisture and light.

Levothyroxine absorption and activity can be altered by several medicines.

Major Interactions (Avoid): - Antacids containing aluminum or magnesium: reduce levothyroxine absorption. - Calcium supplements: impair intestinal uptake of the drug. - Iron preparations: decrease bioavailability when taken together. - Warfarin: may enhance anticoagulant effect, requiring INR monitoring. - Amiodarone: can modify thyroid hormone metabolism.

Moderate Interactions (Monitor Closely): - Beta‑blockers: may mask symptoms of excess thyroid hormone. - SSRIs: potential for increased serotonergic activity when thyroid levels rise. - Diabetes medications: thyroid hormone may affect glucose control, necessitating dose adjustments.
