USE

SYNTHROID® (levothyroxine sodium tablets, USP) is a prescription, man-made thyroid hormone that is used to treat a condition called hypothyroidism, except in cases of temporary hypothyroidism, which is usually associated with an inflammation of the thyroid gland (thyroiditis). It is meant to replace a hormone that is usually made by your thyroid gland. Generally, thyroid replacement treatment is to be taken for life.

SAFETY CONSIDERATIONS

Thyroid hormones, including SYNTHROID, should not be used either alone or in combination with other drugs for the treatment of obesity or weight loss. In patients with normal thyroid levels, doses of SYNTHROID used daily for hormone replacement are not helpful for weight loss. Larger doses may result in serious or even life-threatening events, especially when used in combination with certain other drugs used to reduce appetite.

What is Synthroid?

Synthroid is a prescription medication that can help treat hypothyroidism. The active ingredient in Synthroid is called levothyroxine sodium. Synthroid can help restore thyroid hormone balance. It is a man-made thyroid hormone identical to thyroxine, the hormone that’s naturally made by the thyroid gland. Generally, thyroid replacement medication is to be taken for life.

  • Thyroid hormones, including SYNTHROID, should not be used for the treatment of obesity or weight loss. Large doses of thyroid hormone, especially when used with certain medicines that reduce appetite, can result in serious and even life-threatening effects.
  • Do not use SYNTHROID if you have hyperthyroidism or over-active thyroid, uncorrected adrenal problems, are having symptoms of a heart attack, or are allergic to any of its ingredients.
  • Talk to your doctor about any medication and food allergies, all medications you are taking, pregnancy plans, and all medical conditions you may have, especially heart disease, diabetes, clotting disorders, and adrenal or pituitary gland problems.
  • Tell your doctor if you experience rapid or irregular heartbeat, chest pain, shortness of breath, leg cramps, headache, nervousness, irritability, sleeplessness, tremors, change in appetite, weight gain or loss, vomiting, diarrhea, excessive sweating, heat intolerance, fever, changes in menstrual periods, hives or skin rash, or any other unusual medical event.

How does Synthroid Work?

In most cases, you will take thyroid replacement medication every day as your doctor prescribed. When you first start taking Synthroid, it’s very important for your doctor to monitor you closely. He or she will usually test your TSH levels every 6 to 8 weeks to make sure you’re on the right dose. Finding the right Synthroid dose for you may take some time. Keep in mind that everyone is unique.

During the first months of treatment, the doctor will work with you to find the right dose to get your TSH levels in range. The doctor will check how you’re doing on your prescribed Synthroid dose and ask you if you’re still experiencing any symptoms. Since each person is unique, some people may need a low dose of Synthroid to help replace the amount of thyroid hormone that’s missing. Others may need a higher dose.

Synthroid helps restore thyroxine levels

With hypothyroidism, the thyroid hormone is too low.

SYNTHROID replaces the thyroxine your thyroid can’t make anymore, helping restore your thyroxine levels.

Over time your thyroid hormone needs can change, and your dose of Synthroid might need to change as well. It’s important to continue your partnership with your doctor and discuss any symptoms you may be experiencing. After talking with you, your doctor will determine if you need a change in dose. Remember, your medicine doesn’t work if you don’t take it. You play a major role in managing your hypothyroidism by taking your Synthroid every morning as prescribed by your doctor.

About Synthroid Dosing

Doctors have been prescribing Synthroid for over 50 years. Synthroid comes in 12 dosing options to help doctors find the dose that’s right for you. Your doctor will determine your starting dose based on weight, age, cause of hypothyroidism, other health conditions you have, and other medications you are taking.

SYNTHROID® (levothyroxine sodium tablets, USP) is a prescription, man-made thyroid hormone that is used to treat a condition called hypothyroidism, except in cases of temporary hypothyroidism, which is usually associated with an inflammation of the thyroid gland (thyroiditis).

Important Safety Information

  • Thyroid hormones, including SYNTHROID, should not be used either alone or in combination with other drugs for the treatment of obesity or weight loss. In patients with normal thyroid levels, doses of SYNTHROID used daily for hormone replacement are not helpful for weight loss. Larger doses may result in serious or even life-threatening events, especially when used in combination with certain other drugs used to reduce appetite.

  • Do not use SYNTHROID if you have hyperthyroidism or over-active thyroid, uncorrected adrenal problems, are having symptoms of a heart attack, or are allergic to any of its ingredients.

  • In women, long-term treatment with SYNTHROID has been associated with increased bone loss, especially in women who are on high doses or those who are on high doses after menopause.

  • Tell your doctor if you are allergic to any foods or drugs, are pregnant or plan to become pregnant, are breast-feeding or are taking any other drugs, as well as prescription and over-the-counter products.

  • Tell your doctor about any other medical conditions you may have, especially heart disease, diabetes, blood clotting problems, and adrenal or pituitary gland problems. The dose of other drugs you may be taking to control these conditions may have to be changed while you are taking SYNTHROID. If you have diabetes, check your blood sugar levels and/or the glucose in your urine, as ordered by your doctor and immediately tell your doctor if there are any changes. If you are taking blood thinners, your blood clotting status should be checked often.

  • Use SYNTHROID only as ordered by your doctor. Do not stop or change the amount you take, or how often you take it, unless told to do so by your doctor.

  • Products such as iron and calcium supplements and antacids can lower your body’s ability to absorb SYNTHROID, so SYNTHROID should be taken 4 hours before or after taking these products.

  • Take SYNTHROID as a single dose, preferably on an empty stomach, one-half to one hour before breakfast. Your body’s ability to absorb SYNTHROID is improved when you take it on an empty stomach.

  • Tell your doctor if you develop any of the following symptoms: rapid or abnormal heartbeat, chest pain, difficulty catching breath, leg cramps, headache, feeling nervous, irritability, sleeplessness, shaking, change in appetite, weight gain or loss, throwing up, diarrhea, increased sweating, unable to tolerate heat, fever, changes in menstrual periods, swollen red bumps on the skin or skin rash, or any other unusual medical event.

  • Tell your doctor or dentist that you are taking SYNTHROID before any surgery.

  • Once your body’s response to SYNTHROID has stabilized, it is important to have lab tests done, as ordered by your doctor, at least once a year.

This is the most important safety information you should know about SYNTHROID. For more information, talk with your doctor.
