Thyroxine Sodium 100mcg Tablets

Product Introduction

Thyroxine Sodium 100mcg is a thyroid-hormone replacement used for hypothyroidism, including deficiency after thyroid surgery or radioiodine treatment. It replaces the T4 that an underactive or absent thyroid cannot supply adequately.

How to use

Take once daily with water on an empty stomach, 30–60 minutes before breakfast, tea or coffee. Keep a gap of at least four hours from calcium, iron, aluminium-containing antacids and medicines that bind thyroid hormone. Use the same daily routine to keep absorption consistent.

How it works

Levothyroxine, also called thyroxine, replaces the natural hormone T4. Body tissues convert part of it to active T3, which regulates metabolism, energy use, temperature and other thyroid-dependent functions.

Side effects

At an appropriate replacement dose, many people have no noticeable adverse effects. Excess exposure can cause palpitations, tremor, sweating, anxiety, diarrhoea, insomnia or weight loss. Chest pain or a rapid irregular heartbeat needs prompt medical attention.

Important information

Tell your doctor about heart disease, an irregular heartbeat, adrenal insufficiency, diabetes, osteoporosis and medicines such as warfarin. Untreated adrenal insufficiency must be corrected before thyroid replacement. Changes in absorption or body weight can alter the required dose, and excess replacement can harm the heart and bones.
