Indications & Clinical Uses

Levothyroxine sodium is primarily used to treat an underactive thyroid gland, a condition known as hypothyroidism. It may also be prescribed to prevent the recurrence of thyroid cancer after surgery. The medication works by replacing the hormone that your thyroid gland cannot produce enough of. It is not used for weight loss or fatigue unrelated to thyroid issues.

Side Effects

This medication helps restore normal thyroid hormone levels, which can improve energy levels, metabolism, and overall well-being. Users may notice gradual improvements in symptoms such as fatigue, weight gain, and cold intolerance over several weeks. It does not provide immediate effects and requires consistent daily use.

Precautions & Warnings

Take this medication exactly as prescribed by your healthcare provider, usually once daily on an empty stomach, 30-60 minutes before breakfast. Avoid taking it with calcium, iron, or other supplements unless directed by your doctor. Keep the medication in its original container, tightly closed, and away from moisture and heat.

Avoid Interactions

Levothyroxine can interact with certain medications, including antacids, calcium supplements, and iron tablets, which may reduce its absorption. Inform your doctor about all prescription and over-the-counter drugs you are taking. Separate doses of levothyroxine and these interacting substances by at least 4 hours to minimize interference.
