Vandetanib

Summary

  • Vandetanib is used to treat certain types of thyroid cancer, specifically medullary thyroid cancer, which is a cancer that starts in the cells of the thyroid gland. It is usually prescribed when other treatments have not been effective.

  • Vandetanib works by blocking proteins called tyrosine kinases, which help cancer cells grow and spread. By turning off these proteins, Vandetanib slows down the progression of cancer and can improve survival rates in patients with certain thyroid cancers.

  • The usual starting dose of Vandetanib for adults is 300 mg taken once daily. It is important to swallow the tablet whole, without crushing or chewing it, and it can be taken with or without food. Always follow your doctor's specific dosing instructions.

  • Common side effects of Vandetanib include diarrhea, rash, and nausea, which are unwanted reactions to the medication. These effects can vary from person to person, and if they persist or worsen, it is important to contact your doctor for advice.

  • Vandetanib can cause serious heart rhythm problems, so regular monitoring is necessary. It is contraindicated in patients with congenital long QT syndrome, which is a heart rhythm disorder. Always inform your doctor about any heart problems or low blood calcium levels before starting Vandetanib.
