Medullary thyroid cancer cannot be removed with surgery or has spread to other parts of the body.

Caprelsa works by slowing down the growth of new blood vessels in (cancer) tumors. In this way, the supply of nutrients and oxygen to the tumor is restricted. Caprelsa can also have a direct effect on cancer cells by killing the cells or slowing down the growth.

  • if you are allergic to vandetanib or any of the other ingredients of this medicine (listed in section 6).
  • if you have a congenital heart disease called ‘long QTc’ syndrome. This can be seen on the electrocardiogram ( ECG ).
  • if you are breast-feeding.
  • if you are taking any of the following medicines: arsenic, cisapride (used to treat heartburn), intravenous erythromycin and moxifloxacin (used to treat infection ), toremifene (used to treat breast cancer), mizolastine (used to treat allergies ), class IA antiarrhythmics and III (for heart rhythm control).
