L-Thyroxin 175 1 A Pharma

Levothyroxine, the active ingredient in L-Thyroxin 175 1 A Pharma, is a thyroid hormone presented as a 175 µg oral tablet for systemic use. It replaces deficient thyroid hormone and is prescribed for patients with hypothyroidism, post‑thyroidectomy hormone replacement, and certain cases of goiter.

GNH USA supplies L-Thyroxin 175 1 A Pharma as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, ensuring consistent quality and regulatory compliance across markets.

Levothyroxine is used to treat disorders of thyroid hormone deficiency and related conditions.

- Hypothyroidism: restores normal thyroid hormone levels and alleviates symptoms such as fatigue, weight gain, and cold intolerance. - Post‑thyroidectomy hormone replacement: provides the necessary thyroxine after surgical removal of the thyroid gland. - Goiter: helps normalize thyroid hormone feedback, reducing gland enlargement in iodine‑deficient or autonomous nodular goiter.

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

Common Side Effects: - Headache - Insomnia - Increased appetite - Tremor - Palpitations - Heat intolerance

Serious or Rare Side Effects: - Chest pain or angina - Cardiac arrhythmias - Severe bone loss (osteoporosis) - Hyperthyroid symptoms such as rapid weight loss, anxiety, and heat intolerance - Allergic reactions including rash, swelling, or anaphylaxis

When prescribing Levothyroxine, clinicians should consider several safety precautions.

- Dose titration: adjust dose gradually in elderly patients to avoid overtreatment. - Thyroid monitoring: regularly check TSH and free T4 levels to maintain therapeutic range. - Cardiovascular risk: use caution in patients with coronary artery disease or arrhythmias. - Adrenal insufficiency: ensure adequate glucocorticoid coverage before initiating therapy. - Pregnancy and lactation: evaluate risk‑benefit and monitor thyroid function closely. - Store below 25°C: keep in the original container, protect from moisture and light.

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

Major Interactions (Avoid): - Antithyroid agents (e.g., methimazole, propylthiouracil) – antagonize therapeutic effect. - Lithium – may increase hypothyroid symptoms. - Amiodarone – alters thyroid hormone metabolism. - Cholestyramine or other bile‑acid sequestrants – reduces levothyroxine absorption. - Sucralfate – binds levothyroxine in the gut, decreasing bioavailability.

Moderate Interactions (Monitor Closely): - Calcium or iron supplements – may impair absorption; separate dosing by at least 4 hours. - Proton pump inhibitors – can modestly reduce absorption. - Warfarin – levothyroxine may enhance anticoagulant effect; monitor INR. - Oral contraceptives – may increase thyroid‑binding globulin, requiring dose adjustment. - Rifampin – may increase metabolism, potentially lowering serum levels.
