Drug | Tablet

Hypothyroidism (underactive thyroid), congenital hypothyroidism, thyroid hormone replacement after thyroidectomy or radioiodine therapy, TSH suppression in differentiated thyroid cancer (as advised by specialist)

Levothyroxine is a synthetic form of thyroxine (T4), a natural thyroid hormone. It is converted to the active hormone triiodothyronine (T3) in tissues, which regulates metabolism, energy, growth and body temperature, thereby normalizing thyroid function and TSH levels.

Oral tablet. Take once daily on an empty stomach, preferably in the morning 30–60 minutes before breakfast with water; take at the same time each day. Avoid taking with calcium/iron/antacids or multivitamins—keep a 4-hour gap. Dose is individualized based on TSH and clinical response; do not stop or change dose without doctor advice.
