Eltroxin Tablet Uses, Dosage, Side Effects & Price in Pakistan

1. Quick Info (Mukhtasir Maloomat)

2. What is Eltroxin Tablet? (Eltroxin Tablet kya hai)

Eltroxin Tablet contains levothyroxine sodium, a synthetic form of thyroxine (T4), the main hormone secreted by the thyroid gland. Levothyroxine replaces or supplements insufficient endogenous thyroid hormone, restoring normal metabolic function. After absorption, T4 is converted peripherally (primarily in the liver and kidneys) to the more biologically active triiodothyronine (T3), which then binds to thyroid hormone receptors in target tissues to regulate metabolism, heart rate, body temperature, and growth.

Because it is dosed to produce physiological thyroid hormone levels, Eltroxin is generally well tolerated when maintained within the therapeutic range. The target is a normal TSH (thyroid-stimulating hormone) level on regular monitoring. Compared to T3-containing preparations, levothyroxine provides a more stable and predictable hormone profile, which is why it is the standard of care for hypothyroidism worldwide. Always take Eltroxin Tablet as directed by your doctor or pharmacist.
