Product introduction
Thyronorm 12.5mcg Tablet is a low-strength, synthetic form of the thyroid hormone thyroxine. It is used to treat hypothyroidism, where the thyroid gland does not make enough hormone on its own. By making up for the shortfall, it helps bring energy, metabolism, mood, and other body functions back toward normal. This small dose is often used when starting treatment or for fine adjustments. It is taken on an empty stomach before the first meal, and therapy usually continues long term with regular thyroid tests.
