L-Thyroxin 150 1 A Pharma (Levothyroxine Sodium)

Levothyroxine is a synthetic analogue of the natural thyroid hormone thyroxine (T4). After oral absorption it is converted to the active form triiodothyronine (T3) inside cells, where it binds nuclear thyroid hormone receptors and regulates gene transcription that controls basal metabolic rate, protein synthesis, and growth, thereby correcting hormonal deficiency.

The appropriate dose of L‑Thyroxin is individualized by the prescribing clinician based on age, weight, severity of hypothyroidism, and serum thyroid‑stimulating hormone (TSH) levels. Dosage adjustments are made during follow‑up to achieve target TSH values, and patients should follow the prescriber’s instructions without self‑adjusting the dose.

Levothyroxine is generally considered safe in pregnancy and lactation because adequate thyroid hormone is essential for fetal development and maternal health. However, dosing may need adjustment due to increased hormone requirements. Women who are pregnant, planning pregnancy, or breastfeeding should discuss therapy with their healthcare provider to ensure optimal management.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity of L‑Thyroxin 150 µg tablets. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details, and any necessary import documentation.

L‑Thyroxin contains levothyroxine sodium, the standard synthetic T4 used for most thyroid replacement therapies. Compared with combination T4/T3 products, levothyroxine offers a stable, once‑daily dosing regimen and a well‑characterized safety profile. It is generally preferred for primary hypothyroidism, while combination preparations may be reserved for specific cases where T3 supplementation is required.

L‑Thyroxin tablets should be stored at ambient temperature, below 25 °C, in their original blister or bottle to protect from moisture and light. Keep the medication out of reach of children and avoid storing in bathrooms or near heat sources. Do not use if the packaging is damaged or the tablets appear discolored.

L‑Thyroxin is taken orally, usually on an empty stomach, at least 30 minutes before breakfast or any other medication. Swallow the tablet whole with a full glass of water; do not crush or chew it. Consistent timing each day helps maintain stable serum hormone levels, and patients should follow the dosing schedule prescribed by their clinician.

Serious risks include cardiac arrhythmias, angina, and exacerbation of osteoporosis, particularly when the dose is excessive or in patients with pre‑existing heart disease or bone loss. Over‑replacement can also cause symptoms of hyperthyroidism such as tremor, heat intolerance, and weight loss. Regular monitoring of thyroid function tests and clinical assessment helps mitigate these risks.

Levothyroxine is contraindicated in patients with untreated adrenal insufficiency, acute myocardial infarction, or uncorrected thyrotoxicosis. Individuals with known hypersensitivity to levothyroxine sodium or any excipients in the tablet should avoid its use. Clinicians should evaluate these conditions before initiating therapy and consider alternative management strategies when appropriate.
