Liothyronine Sodium
About Liothyronine Sodium
Liothyronine Sodium is a medication used to treat an underactive thyroid, a condition medically known as hypothyroidism. It helps replace or supplement the natural thyroid hormones your body is not making enough of. This medicine is also used to manage certain types of goitres (enlarged thyroid gland) and to test how well your thyroid gland is working.
To get the best results, you need to take Liothyronine Sodium consistently every day, preferably at the same time. It is typically taken once a day on an empty stomach, usually 30 to 60 minutes before breakfast, to ensure your body absorbs it fully. Eating a balanced diet and managing your stress levels can also help support your overall thyroid health and energy levels during your treatment.
While taking this medicine, you might experience mild side effects like temporary hair loss, especially during the first few months. However, if you notice serious signs such as a rapid or irregular heartbeat, chest pain, or severe nervousness, you must contact your doctor immediately.
Talk to your doctor before starting this medicine if you have certain health conditions, especially heart problems, high blood pressure, or problems with your adrenal glands. Do not take this if you have an overactive thyroid (hyperthyroidism) that is not being treated, or if you have recently had a heart attack.
Liothyronine Sodium can interact with other medicines, including blood thinners, certain cholesterol-lowering drugs, and calcium or iron supplements, which can prevent your body from absorbing this medicine properly. If you are pregnant, breastfeeding, or an older adult, consult your doctor as your dosing requirements may need careful monitoring.

Patients Concern
Disease/Condition Glossary
Hypothyroidism: Hypothyroidism is also known as underactive thyroid, a chronic condition when the thyroid gland does not make enough thyroid hormones to meet your body’s needs. When there is a low level of thyroid hormones, our body’s functions and metabolism slow down. Symptoms of hypothyroidism include tiredness, increased sensitivity to cold, constipation, dry skin, unexplained weight gain, puffy face, hoarseness of voice, and muscle weakness. There may be a loss of Calcium and Vitamin D in some cases of hypothyroidism.
