EGP550
What is Eltroxin 100 mcg?
Eltroxin is a widely prescribed medication that contains Thyroxine Sodium (100 mcg), a synthetic form of the thyroid hormone thyroxine (T4). This medicine is used to treat hypothyroidism, a condition where the thyroid gland does not produce sufficient thyroid hormones.
Thyroid hormones are essential for controlling metabolism, energy production, heart health, and brain function. Without enough thyroid hormones, patients may suffer from fatigue, weight gain, hair loss, dry skin, irregular periods, and even depression. Eltroxin replaces the missing hormone and helps restore balance.
Indications & Uses of Eltroxin
Eltroxin 100 mcg is prescribed for:
Primary hypothyroidism (underactive thyroid)
Goiter management (enlarged thyroid gland)
Post-thyroidectomy therapy (after surgical removal of the thyroid)
Thyroid cancer treatment (as part of suppression therapy)
Congenital hypothyroidism (thyroid hormone deficiency in newborns)

Dosage & Administration
Usual starting dose: 25 mcg to 100 mcg daily, adjusted according to thyroid blood tests.
Taken once daily, preferably in the morning on an empty stomach with a glass of water.
Food, calcium, and iron supplements can reduce absorption, so take them at least 2 hours apart.
Treatment is usually lifelong for chronic hypothyroidism.
