How is hypothyroidism
diagnosed?

You can be tested with a simple blood test1

A TSH (thyroid stimulating hormone) test is the common way to test for hypothyroidism. It measures the level of thyroxine
your thyroid produces. An abnormally high TSH means hypothyroidism: the thyroid gland is being asked to make more hormones
because there isn’t enough in your blood.1

Sometimes further testing may be needed to confirm a diagnosis.1

Hypothyroidism can lead to serious problems if not treated.2

Synthroid® is a tailored levothyroxine
treatment for hypothyroidism.1

Hypothyroidism can’t be cured, but it can be controlled

Taking Synthroid® every day replaces the hormones that your body no longer makes enough of, to get you back to normal.
The amount of medicine has to be carefully worked out for you to avoid giving you too much or too little, and your
doctor will ensure you’ve got the right dose. Do not change the amount you take or how often you take
Synthroid®, unless directed to do so by your doctor.

What is Synthroid®1?

Synthroid® contains levothyroxine, which is similar to the thyroxine your body naturally produces.
You can view the Synthroid® Consumer Medicine Information sheet here.

Synthroid® is usually taken for life – don’t stop taking it, even if you are
feeling better, unless directed by your doctor.

Managing your hypothyroidism with Synthroid®

Take Synthroid® as a single dose, preferably on an empty stomach, 30 minutes to one hour before breakfast.1

Synthroid® should be taken at the same time every day with a full glass of water.1

Food and drink can change the way your body absorbs Synthroid®, so always take it on an empty stomach.1

If you forget to take a tablet, take it as soon as you remember. Don't double your dose if the time for your next dose is close.1

If you miss two or more doses in a row, check with your doctor, and always take Synthroid® exactly as your
doctor has prescribed it.1

If you’ve started treatment for hypothyroidism, it’s important to keep
your doctor up to date with how you’re feeling.
