What do levothyroxine sodium tablets treat?
Levothyroxine sodium tablets are used to replace or supplement thyroid hormone in people who do not make enough naturally. This is most often prescribed for hypothyroidism (low thyroid function).
They’re also used to treat certain thyroid-related conditions where reducing or regulating thyroid hormone signaling is needed, based on a clinician’s diagnosis and dosing plan.
What condition is it commonly prescribed for (hypothyroidism)?
The most common use is treating hypothyroidism, including when the thyroid is underactive due to causes such as autoimmune thyroid disease or after thyroid surgery or radiation. By supplying thyroid hormone, levothyroxine helps bring thyroid hormone levels back toward normal.
Who typically takes levothyroxine tablets?
Levothyroxine is used in adults and children who have hypothyroidism. It may also be prescribed after removal or treatment of the thyroid, where the body no longer produces enough thyroid hormone.
Why is thyroid hormone replacement important?
Thyroid hormone affects many body systems, including metabolism and growth. When it’s low, symptoms can include fatigue, weight gain, cold intolerance, constipation, and slowed heart rate. Levothyroxine is intended to reverse these effects by restoring hormone levels.
When patients have questions about dosing
Levothyroxine works over time, and dose adjustments are often based on follow-up lab tests (typically thyroid-stimulating hormone, TSH, and sometimes free T4). Taking it consistently as directed is important because absorption and effectiveness can vary.
