About Synthroid

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 to use Synthroid

Use Synthroid as directed by your doctor.
Take Synthroid with a full glass (8 ounces) of water. Take this medicine on an empty stomach, 30 minutes before eating. Synthroid is usually taken in the morning. Ask your health care provider any questions you may have about how to use Synthroid.

Synthroid Precautions:

Do NOT use Synthroid if:

• you are allergic to any ingredient in Synthroid;
• you have a history of heart attack, chest pain (angina), adrenal gland problems, or elevated thyroid hormone levels that have not been treated.
• Contact your doctor or health care provider right away if any of these apply to you.
