Product introduction
Eltroxin 50mcg Tablet is often the starting or maintenance strength used to treat an underactive thyroid, especially in people with mild deficiency or those just beginning treatment. It contains synthetic thyroxine, which substitutes for the hormone the thyroid gland isn't producing enough of on its own. Because thyroid hormone needs vary from person to person, the dose is usually fine-tuned over weeks based on how the patient responds and what blood tests show. Taking it consistently, at the same time each day, helps keep hormone levels steady.
Storage: Store below 25 degrees Celsius, away from direct sunlight and moisture. Keep out of reach of children.

Frequently asked questions
Is 50mcg a starting dose or a long-term dose?
It can be either. Some people start at 50mcg and stay on it if their thyroid tests remain normal, while others begin here and are gradually stepped up based on follow-up blood work.
Can I take Eltroxin 50mcg at night instead of morning?
Some doctors do allow bedtime dosing as long as it's taken on an empty stomach, at least a few hours after your last meal. Follow whatever schedule your doctor recommends and stick to it consistently.
What if I accidentally take an extra tablet?
Contact your doctor promptly, especially if you notice palpitations, chest pain, or unusual restlessness, since an excess dose can overstimulate the heart and metabolism.
How soon will I feel better after starting this medicine?
Most people notice gradual improvement in energy and other symptoms over several weeks, as thyroid hormone levels take time to stabilise.
Do I need to take this medicine forever?
In most cases of hypothyroidism, yes — it is a lifelong replacement therapy, though your doctor will confirm this based on the underlying cause.
