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.

How to take Synthroid

It’s important to take Synthroid exactly as your doctor prescribed. Creating a routine can help you take it the same way every day. Make sure you’re taking Synthroid as your doctor prescribed to help you manage your hypothyroidism.

Tips on taking Synthroid every morning

Same time, every morning

Take Synthroid once a day at the same time every day.

Synthroid Q&A

Are there foods that may interfere with the way Synthroid works?

Yes. Certain foods such as soy, fiber, cottonseed meal, and walnuts can affect the absorption of Synthroid. If you eat any of these foods on a regular basis, check with your doctor. He or she might have to adjust your dose of Synthroid.

How should I take certain supplements?

Some supplements can affect the way hypothyroidism treatments work. To avoid this, take Synthroid 4 hours before or after taking these supplements:

  • Iron supplements or multivitamins with iron
  • Calcium supplements or multivitamins with calcium
  • Antacids

Remember to take Synthroid every morning on an empty stomach, one-half to one hour before breakfast.

What do I do if I miss a dose?

Call your doctor for advice on what you should do.

What do I do if I miss more than one dose?

Call your doctor for advice on what you should do.

What do I do on weekends and holidays?

Take Synthroid as you usually do, as your doctor prescribed.

What do I do while traveling?

Remember to pack more tablets than you need in your carry-on bag or purse in case you get delayed or decide to stay longer. Plan ahead so you don’t run out of Synthroid while you’re away.

When traveling to another country or time zone, ask the doctor or pharmacist if you need to adjust the time of day for taking Synthroid.

What do I do about refills?

Always refill your Synthroid prescription before it runs out. If your doctor prefers Synthroid, make sure you’re getting Synthroid at every refill. At every refill, check to see if your pill says “SYNTHROID.” Remember, only Synthroid has the name “SYNTHROID” embossed on every pill.

Do I still need to take Synthroid if I don’t have any more symptoms?

Even if your hypothyroidism symptoms go away, do not stop taking Synthroid or change the way you take it without talking to your doctor. If you don't take your pills each day as prescribed, your doctor may not be able to tell if your current Synthroid dose is right for you.

How do I store Synthroid?

Keep Synthroid protected in its original bottle or place in a pill case, away from light and moisture, and store at room temperature 25°C (77°F).

Can Synthroid be taken for weight loss?

You should NEVER take hypothyroidism medication to treat obesity or for weight loss.

When does my Synthroid dose need to be adjusted, if ever?

When you start taking Synthroid, it’s very important for the doctor to monitor you closely. Your Synthroid dose may need to be adjusted over the course of several weeks before the doctor finds the dose that’s right for you. Throughout your lifetime, the doctor may also need to adjust your dosage. This is because the amount of thyroid hormone you need may change over time or with major life changes such as pregnancy and menopause.

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.

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.
