Composition of Eltroxin 100 Tablet

Eltroxin 100 Tablet contains Thyroxine (100mcg). It belongs to the Synthetic thyroid hormone (T4) class of medicines.

  • Hypothyroidism
  • Thyroid hormone replacement after thyroidectomy
  • TSH suppression therapy in certain thyroid cancers
  • Goitre (as prescribed)

Benefits of Eltroxin 100 Tablet

In Hypothyroidism
Eltroxin replaces the thyroid hormone your gland is no longer making, restoring energy, concentration, body temperature and weight to normal. Taken every day, it lets you live a completely normal life.
In Goitre
Eltroxin supplies the thyroid hormone the body lacks, which can shrink an enlarged thyroid gland and stop it growing further.
In Thyroid hormone replacement
Eltroxin provides the thyroid hormone your body cannot make itself, for example after thyroid surgery or radioiodine treatment, so metabolism stays normal.

How Eltroxin 100 Tablet works

Levothyroxine is synthetic T4 thyroid hormone that is converted to active T3 in tissues. It restores normal thyroid hormone levels, improving metabolism, energy, and temperature regulation.

How to take Eltroxin 100 Tablet

Take once daily on an empty stomach with water, preferably in the morning 30-60 minutes before breakfast. Take at the same time daily and avoid taking with calcium/iron/antacids; keep a 4-hour gap. Dose is individualized based on TSH levels.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
