L-Thyroxin Bc (Levothyroxine Sodium)

Levothyroxine sodium is a synthetic form of T4 that is absorbed from the gastrointestinal tract, converted to the active T3 in peripheral tissues, and binds nuclear thyroid‑hormone receptors. This interaction regulates gene transcription, increases basal metabolic rate, and supports normal growth and metabolism.

The appropriate dose of L‑Thyroxin Bc is individualized. A qualified prescriber determines the exact amount based on the patient’s age, weight, severity of hypothyroidism, and laboratory thyroid‑stimulating hormone (TSH) levels. No standard dosing regimen is provided here.

Safety data for levothyroxine sodium in pregnancy and lactation are limited, and the product’s pregnancy category is listed as unknown. It should only be used when the potential benefit justifies any possible risk to the fetus or infant, and treatment decisions must be made by a healthcare professional.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements), and necessary import documentation.

L‑Thyroxin Bc is a levothyroxine‑only formulation, providing a stable source of synthetic T4. Alternative products may combine T4 with T3 (liothyronine) or use different salt forms. Levothyroxine‑only therapy is generally preferred for most patients because it mimics natural thyroid hormone physiology and offers predictable dosing.

Store the tablets at ambient temperature, preferably below 25 °C. Keep them in the original blister pack or container, protect from moisture, heat, and direct sunlight. Do not store in bathrooms or near kitchen appliances that generate steam.

L‑Thyroxin Bc is taken orally, usually with a full glass of water. It is commonly recommended to take the tablet on an empty stomach, at least 30‑60 minutes before breakfast, to optimise absorption and minimise interactions with food or supplements.

Serious risks include allergic reactions such as rash or angioedema, cardiac arrhythmias (especially atrial fibrillation) in susceptible individuals, myocardial ischemia, and long‑term bone loss leading to osteoporosis when overtreatment causes excessive thyroid hormone levels.

Patients with untreated thyrotoxicosis, acute myocardial infarction, or uncorrected adrenal insufficiency should avoid levothyroxine therapy until those conditions are managed. Additionally, individuals with known hypersensitivity to levothyroxine sodium or any excipients in the tablet should not use the product.
