Synthroid treats hypothyroidism (low thyroid hormone). It is also used to treat or prevent goiter (enlarged thyroid gland), which can be caused by hormone imbalances, radiation treatment, surgery, or cancer.
How Taken
Use Synthroid as directed by your doctor.
Ask your health care provider any questions you may have about how to use Synthroid.
Drug Class and Mechanism
Synthroid is a replacement for a hormone that is normally produced by your thyroid gland to regulate the body's energy and metabolism. Synthroid is given when the thyroid does not produce enough of this hormone on its own.
Missed Dose
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take extra medicine to make up the missed dose.
Storage
Store Synthroid between 68 and 77 degrees F (20 and 25 degrees C) in a tightly closed, light-resistant container. Store away from moisture, heat, and light. Do not store in the bathroom. Do not take tablets after the expiration date printed on the label. Keep Synthroid out of the reach of children and away from pets.
