Thyroxine (25mcg)

Thyroxine (25mcg) — Uses and Benefits

Thyroxine (25mcg) is mainly used to treat hypothyroidism, a condition where the thyroid gland does not make enough thyroid hormone for the body's needs.

WHAT THIS MEDICINE IS USED FOR

• Treating hypothyroidism (underactive thyroid)
• Managing thyroid hormone deficiency after thyroid surgery or radiation treatment
• Helping control goitre (enlarged thyroid) in some cases
• Used along with other treatment in some cases of thyroid cancer, as directed by your doctor

HOW IT WORKS

• Thyroxine replaces or supplements the natural hormone your thyroid gland is not making enough of
• This helps restore normal metabolism, energy levels, and body functions that depend on thyroid hormone
• It works gradually, and blood tests are needed to check if the dose is right for you

WHAT IT IS NOT USED FOR

• It is not used to treat overactive thyroid (hyperthyroidism)
• It is not a weight-loss medicine and should never be used for that purpose
• It is not meant for general tiredness or fatigue unless caused by low thyroid hormone levels
