Levothyroxine 100 mcg

Levothyroxine 100 mcg

Levothyroxine 100 mcg is a widely prescribed medication for hypothyroidism, a condition where the thyroid gland produces insufficient hormones. Thyroid hormones regulate metabolism, energy production, and several critical bodily functions. Levothyroxine 100 mcg replaces or supplements thyroid hormones to restore normal metabolic activity, reduce symptoms like fatigue, weight gain, and cold intolerance, and support overall health.

What is Levothyroxine 100 mcg?

Levothyroxine 100 mcg is a synthetic form of thyroxine (T4), the main hormone produced by the thyroid gland. It is prescribed for:

• Hypothyroidism (underactive thyroid)

• Goiter (enlarged thyroid)

• Thyroid hormone replacement after thyroid surgery

• Congenital hypothyroidism in children

Levothyroxine 100 mcg restores hormone balance, supporting proper metabolism, energy levels, and overall organ function.

How Levothyroxine 100 mcg Works

Levothyroxine 100 mcg is absorbed into the bloodstream and converted into triiodothyronine (T3), the active form of thyroid hormone. T3 binds to cellular receptors to regulate metabolism, growth, and energy production. Maintaining adequate hormone levels helps alleviate hypothyroidism symptoms and supports normal organ function.
