- Vandetanib may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting). Get medical help right away if you have any of these symptoms.<br /><br /> The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may affect the heart rhythm (see also Drug Interactions). Do not use vandetanib if you have a certain heart problem (long QT syndrome). Before using vandetanib, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation/long QT syndrome), family history of certain heart problems (QT prolongation/long QT syndrome, sudden cardiac death).<br /><br /> Vandetanib should not be used in people with low levels of calcium, potassium, or magnesium in the blood. Low levels of these minerals may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting.<br /><br /> To lower your risk, your doctor will check your mineral levels with a blood test and your heart with a test (EKG) before and periodically during treatment. Low mineral levels should be corrected before you start treatment. If you develop QT prolongation, your doctor may stop treatment for a while and restart it at a lower dose, and check your EKG again.<br /><br /> Since vandetanib stays in your body for a long time, it may take a while for side effects such as QT prolongation to go away after you stop taking it. Discuss the risks and benefits of treatment with your doctor. This medication is only available through a restricted program from certified prescribers and pharmacies called the Vandetanib REMS Program.<br /><br />These requirements apply in the United States. If you live in Canada or any other country, consult your doctor and pharmacist for your country's regulations.
