Synthroid (levothyroxine sodium) is a prescription thyroid medication that replaces the hormone normally produced by the thyroid gland, essential for regulating energy and metabolism. It is primarily used to treat hypothyroidism when the body does not produce enough thyroid hormone. Synthroid is also used alongside surgery and radioiodine therapy to manage well-differentiated thyroid cancer. While widely prescribed, it should not be used for weight loss, as misuse—especially with larger doses being used as weight-loss drugs—can lead to severe or fatal side effects.
Before taking Synthroid (levothyroxine sodium), inform your doctor if you have a history of adrenal gland disorders, thyrotoxicosis, heart conditions, or recent radiation therapy. Certain conditions, such as osteoporosis, anemia, diabetes, or thyroid nodules, may also require monitoring or dosage adjustments.
If you become pregnant, do not stop taking Synthroid (levothyroxine sodium) without consulting your doctor, as thyroid hormone levels are crucial during pregnancy. Proper medical guidance ensures safe and effective use of this medication.
