For thyroid conditions, what is different?

Wegovy label information for thyroid conditions
What changesWhat the label says
Risk of Thyroid C-Cell TumorsIn rodents, it caused thyroid C-cell tumors. Whether it causes these tumors in humans is unknown. If medullary thyroid cancer (MTC) appears in your personal or family history, do not use it. It is also not for you if you have MEN 2.
Taken with levothyroxineSemaglutide tablets raised levothyroxine levels in one study, so a check of thyroid levels may be needed.
