What is Synthroid®?

  • SYNTHROID is used when the thyroid gland does not produce enough of the hormone thyroxine.
  • It contains levothyroxine sodium, which is the man-made form of thyroxine.
  • It is intended to help to replace or supplement thyroxine in the body.

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

Take your dose once per day at the same time every day. You should take your dose on an empty stomach, 30 minutes to 1 hour before breakfast.

Food and drink can affect how your body absorbs SYNTHROID®. For this reason, if you do take your dose with food or drink, be sure to take it this way each time. You must be consistent with how you take your dose.

If you forget to take one dose, take it as soon as you remember, unless it is almost time for your next dose. If it is, skip the missed dose and continue with your regular dosing schedule. Do not take two doses at once to make up for a missed dose.

Swallow tablet whole with a full glass of water.

Always take SYNTHROID® exactly as your doctor tells you. If you are using other medicines, your healthcare professional may recommend that you take SYNTHROID® 4 hours before or 4 hours after these other medicines.

If you miss two or more doses in a row, check with your doctor.
