Liothyronine 25mcg Tablets

Product Introduction

Liothyronine 25mcg is a thyroid-hormone replacement for hypothyroidism, an underactive thyroid. It supplies T3, the active hormone involved in the body’s energy use, temperature regulation and normal organ function.

How to use

Take the daily dose with water at consistent times, keeping the same routine in relation to meals. Take liothyronine at least four hours before bile-acid-binding medicines such as cholestyramine or colesevelam, which reduce thyroid-hormone absorption. T3 acts relatively quickly, so dose changes are guided by thyroid blood tests as well as symptoms.

How it works

Liothyronine supplies triiodothyronine, or T3, directly. T3 enters cells and activates thyroid-hormone receptors that regulate gene activity, protein production and metabolism.

Side effects

Excess thyroid-hormone exposure can cause palpitations, tremor, sweating, heat intolerance, diarrhoea, insomnia or muscle weakness. Chest pain, fainting or a persistent rapid or irregular heartbeat needs urgent attention.

Important information

Tell your doctor about angina, an irregular heartbeat, adrenal insufficiency, diabetes or osteoporosis, and about warfarin or diabetes medicines. Untreated adrenal insufficiency must be corrected before thyroid replacement because treatment can trigger an adrenal crisis. Excess replacement can strain the heart and accelerate bone loss.
