The name of your medicine is Oroxine. It is available in tablets of four different strengths: 50 microgram, 75 micrograms, 100 microgram and 200 microgram.
The active ingredient is called thyroxine sodium.
What is Oroxine used for? Thyroxine sodium is a thyroid hormone. It is used as replacement therapy in the treatment of thyroid hormone deficiency.
Oroxine is used to treat:
1.Thyroid hormone deficiency also known as Hypothyroidism Hypothyroidism is a disease in which the thyroid gland is underactive and does not produce enough thyroxine, a hormone, which is important for controlling your metabolism. Symptoms of hypothyroidism include tiredness, muscle weakness, and cramps, feeling the cold, a slow heart rate, dry and flaky skin, hair loss, a deep husky voice and weight gain.
2.Thyroiditis (inflammation of the thyroid gland) such as Hashimoto's disease Hashimoto’s disease is an autoimmune disease (a disease that alters the immune system of the body). An immune reaction against thyroglobulin or some other part of the thyroid tissue has occurred. These patients will also suffer from the same symptoms as those suffering from thyroid hormone deficiency (hypothyroidism).
3.TSH-responsive tumours (certain tumours of the thyroid gland) of the thyroid For these conditions to be treated, patients need a supply of thyroid hormones in their body. Oroxine replaces the shortage of thyroid hormones.
Use Oroxine only as directed.
Your doctor may have prescribed Oroxine for another condition.
Ask your doctor if you have any questions about why Oroxine has been prescribed for you.
Ask your doctor if you have any concerns about taking Oroxine.
