Product introduction
Eltroxin 100mcg Tablet contains synthetic thyroxine, a lab-made version of the hormone your thyroid gland normally produces. It is prescribed when the thyroid is underactive and cannot make enough hormone on its own to keep the body's metabolism running normally. Doctors typically start with a lower strength and adjust the dose over time based on periodic thyroid function tests. Because the effective dose is very individual, this tablet should only be taken exactly as directed by a physician.
Storage: Store below 25 degrees Celsius, away from direct sunlight and moisture. Keep out of reach of children.

How long do I need to take Eltroxin 100mcg Tablet?

Take the missed dose as soon as you remember on the same day. If it's almost time for the next dose, skip the missed one rather than doubling up, and get back to your normal schedule.

Can this tablet be taken with other thyroid or heart medicines?
