A prescription thyroid-hormone medicine containing levothyroxine, a synthetic replacement for the thyroxine naturally produced by the thyroid gland. It is used to replace insufficient thyroid hormone and help restore hormonal balance according to diagnosis and laboratory monitoring, so successful treatment depends on taking it exactly as prescribed and never changing the dose without medical guidance.

Use

Used as part of an individualized treatment plan based on the condition and thyroid blood-test results. Regular monitoring and gradual dose adjustment may be required to identify the appropriate dose for each patient.

Important Information

• Replaces thyroid hormone when the body does not produce enough.
• The dose is individualized according to tests and treatment response.
• Consistent timing and administration help maintain reliable absorption.
• Certain medicines and supplements, including iron, calcium and antacids, may reduce absorption.
• Treatment may be long term depending on the diagnosis and physician's advice.
• It is not intended for weight loss or weight-control programs.

Directions and Warnings

• Take exactly as prescribed, usually on an empty stomach 30–60 minutes before breakfast with water.
• Separate it from iron, calcium and antacids according to the physician or leaflet; product information commonly recommends a four-hour interval.
• Do not change the dose or stop treatment on your own, even if symptoms improve.
• Tell the physician about all medicines and supplements, pregnancy or breastfeeding, and conditions such as heart disease or diabetes.
• Seek medical advice for severe palpitations, chest pain or unusual symptoms, and read the enclosed leaflet carefully.
