Medication Information for: Levothyroxine (Synthroid)

(LEE-vo-THY-rocs-in)

Why? Levothyroxine is used to treat thyroid problems in babies. If the thyroid gland doesn't make enough thyroid hormone, the baby can have problems with growth and development. Giving the thyroid medicine prevents these problems.

How? Give levothyroxine as ordered. Levothyroxine is given once a day. It should be given at the same time of day, usually in the morning.

Your baby's dose is:

_________________ micrograms _____________times a day

at _________o'clock

Crush the tablet to a fine powder and give the powder to the baby. You can mix it with a small amount of water and pour it into a nipple for the baby to take.

Any problems? Most side effects of levothyroxine would be seen in the hospital before the baby goes home. A baby on too much could get jittery and irritable. Don't give levothyroxine with other medicines, especially medicines for making strong bones, like phosphorous and calcium. We recommend that the Synthroid brand of levothyroxine be used. If you choose to change to a generic, let your doctor know. Your baby might need a blood test to make sure the generic is working right. .

How will I know when to stop giving the medicine? Keep giving this medicine each day. Your doctor will do blood tests to see if the medicine is still needed or if the dose needs to be increased.

ALWAYS KEEP ALL MEDICATIONS OUT OF THE REACH OF CHILDREN. Store levothyroxine tablets in at room temperature in a dry place, not the kitchen or bathroom.

Check your supply before vacations, holidays and other times when you may not be able to obtain more.
