Levothyroxine is a synthetic thyroid hormone (T4) used to treat hypothyroidism, a condition in which the thyroid gland does not produce enough hormones. By restoring normal levels of thyroid hormone, levothyroxine helps regulate the body’s energy levels, metabolism, and overall hormonal balance.
This medication is considered the standard of care for long-term management of underactive thyroid function. It is crucial that levothyroxine be dosed based on the patient’s serum thyroid hormone levels and adjusted as needed through regular medical monitoring. Self-dosing or adjusting the dosage without medical oversight can lead to serious health complications, such as heart palpitations or bone loss.
How To Use: The typical dosing instructions are to take once daily in the morning, ideally 30 to 60 minutes before breakfast, with a full glass of water. Best absorbed on an empty stomach; avoid food, calcium, iron, or antacids within 4 hours of taking.
Precautions:
Thyroid function should be monitored with blood tests at least annually or more frequently according to your healthcare provider's advice. Not intended for weight loss or obesity treatment. Overdosing can lead to symptoms of hyperthyroidism, including anxiety, tremor, and fast heartbeat.
