Liothyronine acts by compensating for the lack of thyroid hormones. Its administration eliminates the symptoms triggered by this shortage such as increased sensitivity to cold, lack of energy, weight loss, hair loss and dry skin.

 What is Liothyronine?

Liothyronine is used in the treatment of hypothyroidism, a condition in which the thyroid gland does not produce sufficient amounts of hormones.  

It can also be used to treat goiter and to assess the presence of hyperthyroidism, conditions in which the thyroid, respectively, is enlarged or it produces too many hormones.

How should Liothyronine be taken?

Liothyronine is taken orally in a tablet form, usually with a single dose before breakfast.

The symptoms of hypothyroidism should start to improve after two weeks of treatment, but Liothyronine is not a cure and the medication should be taken for years to come.
