Handling a surprise diagnosis
WENDY, DIAGNOSED WITH HYPOTHYROIDISM
I just had a very normal visit. The doctor walks in the door and acted very strangely. He said, “Are you tired? Have you been having hair loss or fatigue?” No, I’m golden. What’s the problem? He goes, “Because your thyroid is enlarged, and I can see it from across the room.” He did a thyroid test and he put me on a minimum amount of thyroid medicine. And as the couple of weeks went by, they said, “Well, congratulations you’re pregnant.” So my pregnancy and hypothyroidism happened in my world simultaneously. The pregnancy was probably the bigger bombshell for me because I was facing my 45th birthday. I’d already done the mommy thing and was taking kids off to college. For hypothyroidism, the timing of it was a surprise. But I was already watching for it because my grandmother had it.

SYNTHROID® (levothyroxine sodium) tablets, for oral use is a prescription, man-made thyroid hormone that is used to treat a condition called hypothyroidism in adults and children, including infants. 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. SYNTHROID should not be used to treat noncancerous growths or enlargement of the thyroid in patients with normal iodine levels, or in cases of temporary hypothyroidism caused by inflammation of the thyroid gland (thyroiditis).
This is the most important safety information you should know about SYNTHROID. For more information, talk with your doctor.
