THYROXINE SODIUM
About
THYROXINE SODIUM belongs to 'thyroid agents', primarily used to treat underactive thyroid (hypothyroidism). Hypothyroidism is a chronic disorder, which happens when the thyroid gland (located in the front lower part of the neck), is unable to make enough thyroid hormone. The thyroid gland is responsible for releasing hormones, which are composed of tri-iodothyronine (T3) and thyroxine (T4), which helps the body to regulate and use energy. The thyroid controls functions of the heart and digestive system, without the right amount of these hormones, the body is unable to function properly. Early symptoms of this disease are fatigue and weight gain. While other symptoms include feeling cold even in warm weather, dry skin or too much or too few menses (in women), easy fatigueness, constipation, weight gain, or even lack of energy. Right diagnosis and treatment of hypothyroid are important to restore normal physical and mental activity.
THYROXINE SODIUM contains 'Thyroxine sodium' which replaces or provides more thyroid hormone in the body when the body is unable to naturally produce enough thyroid hormone (Thyroxine) to meet the requirements of the body. In this way, THYROXINE SODIUM helps to replace missing thyroid hormone for proper digestion, muscle functioning, brain development, and maintenance of bones.
Take THYROXINE SODIUM exactly in the same way as suggested by the doctor. Usually, THYROXINE SODIUM does not cause any undesirable effects in the body. Still, its overdose may cause diarrhoea, muscle spasm, weight loss, feeling hot even in cool environments, headache, nervousness, sleeplessness, irritability, menstrual irregularities (in women), and skin rash. Thus, it is better to take THYROXINE SODIUM is the same dose, and if you by chance, miss it then do not double the dose for the sake of getting results fast. If a person experiences any of these signs, then their doctor may suggest them to undertake a blood test called 'thyroid function test' which checks three hormones related to thyroid - TSH, T3, T4 to check if the thyroid gland is functioning normally or not.
THYROXINE SODIUM can not be given via mouth in patients dealing with myxedema coma. Your doctor may suggest calcium or vitamin D supplements with THYROXINE SODIUM to improve bone density associated with thyroid hormone overreplacement. Consult with your doctor if the symptoms of low thyroid hormone-like weight gain, slow heartbeat, or sensitivity to cold, tiredness, muscle aches, constipation, dry skin, worsens or persists after a couple of days of taking this drug. If THYROXINE SODIUM is taken by persons having diabetes mellitus, then it may worsen glycemic control and result in increased antidiabetic agent or insulin requirements. Thus it is important to carefully monitor the blood glucose level while starting, changing, or stopping thyroid hormone with THYROXINE SODIUM. The doctor decides the right dose of THYROXINE SODIUM after checking the body weight and thyroid function test report. Regular monitoring of thyroid function is important to check the effectiveness of the medicine.
Uses of THYROXINE SODIUM
Medicinal Benefits
THYROXINE SODIUM is a synthetic thyroid hormone that is prescribed for the treatment of underactive thyroid (hypothyroidism). Thyroxine is the important hormone released by the thyroid gland into the bloodstream. It plays an important role in the functioning of the heart, digestion, muscles, and brain development. THYROXINE SODIUM acts in the same manner as natural Thyroxine does, as it replaces the natural hormone produced by the thyroid gland so that body has enough thyroxine hormone to regulate the body's needs and metabolism. In this way, it helps to replace missing thyroid hormone and/or to relieve stress on the thyroid gland.

Habit Forming
Diet & Lifestyle Advise
- The thyroid gland requires iodine for making its hormone so one should include iodized table salt in their diet. However eating too much can also lead to hyperthyroidism, so take it at a limited level, not too much or not too low.
- A person should eat the right nutrients and a regular dose of THYROXINE SODIUM, which may be linked with hypothyroidism, eat a wide variety of vegetables in your diet.
- People dealing with hypothyroidism, usually notice the loss of calcium (hypocalcemia) and Vitamin D in their body so it is better to include calcium-enriched foods in your diet.
- Persons dealing with hypothyroidism usually have a slower metabolism so eating more amount of protein like eggs, milk, pulses, may help boost the metabolism.
- A person should engage in daily yoga and aerobics exercises that keep a person relaxed and boost their metabolism.
- Persons dealing with hypothyroidism should prefer to take more vegetables, fruits, and lean meats as these foods are low in calories and may help prevent weight gain.
- A person should not take Goitrogens (agents that interfere with the normal function of the thyroid gland) like soy foods (tofu), cabbage, broccoli, kale, cauliflower, spinach, cassava, peaches, strawberries, millet, pine nuts, sweet potatoes, peanuts, etc.
Special Advise
Regular thyroid function tests (T3, T4 and TSH) is required if you are taking THYROXINE SODIUM.
THYROXINE SODIUM is not indicated for the treatment of obesity or weight loss.
Regular monitoring of blood sugars may be advised by your doctor, as THYROXINE SODIUM causes fluctuation in blood sugar levels.
