About Euthyrox 100 Tablet
Euthyrox 100 Tablet is a medication designed to address hypothyroidism, a condition where the thyroid gland does not produce sufficient thyroid hormones. Hypothyroidism can lead to a slowdown in metabolism and various symptoms such as fatigue, weight gain, and feeling cold. Euthyrox 100 Tablet contains thyroxine, a synthetic thyroid hormone that mimics the natural hormone produced by the thyroid gland. By supplementing the missing thyroid hormone, Euthyrox 100 Tablet aims to restore the body's energy levels and metabolic function.
Diagnosis of hypothyroidism involves a thyroid function test to assess levels of TSH, T3, and T4 hormones. An imbalance in these hormones indicates an underactive thyroid. Treatment with Euthyrox 100 Tablet is personalized based on individual body weight and test results. It may take some time for the medication to demonstrate its full effects, and regular monitoring is recommended to ensure the appropriate dosage.
Taking Euthyrox 100 Tablet as prescribed is essential for optimal outcomes. While the medication generally does not cause severe side effects when used correctly, overdose can result in symptoms like headache, weight loss, and muscle spasms. It is crucial not to double the dose if a dose is missed to prevent potential serious side effects. Additionally, calcium or vitamin D supplements may be advised by the doctor to support bone health alongside Euthyrox 100 Tablet treatment.
It is important to note that Euthyrox 100 Tablet should not be used for weight loss purposes alone. Individuals with diabetes should be cautious, as the medication may impact blood glucose control, potentially necessitating adjustments to antidiabetic medications. Monitoring glucose levels is recommended for those with diabetes when starting, changing, or discontinuing thyroid hormone therapy under medical supervision.

By raising hormone levels to the appropriate amount, Euthyrox 100 Tablet helps alleviate these symptoms and effectively controls an underactive thyroid gland.
