sunitinib oral Precautions
Before taking sunitinib, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: bleeding problems, heart problems (e.g., congestive heart failure), high blood pressure, liver problems, thyroid disease.
Sunitinib may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using sunitinib, 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 in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).
Low levels of potassium or magnesium in the blood 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. Talk to your doctor about using sunitinib safely.
To lower the chance of getting cut, bruised or injured, use caution with sharp objects like safety razors or nail cutters and avoid activities such as contact sports.
Wash your hands well to prevent the spread of infections.
Infrequently, people taking sunitinib have had serious jawbone problems (osteonecrosis). Poor dental hygiene, poorly fitting dentures, having certain dental work (such as tooth removal, dental surgery), or also taking bisphosphonate drugs (such as alendronate) may increase your risk. Medical conditions (such as gum disease/infection, cancer, anemia) might also increase the risk. If you develop jaw pain, tell your doctor and dentist immediately.
Before having surgery (including dental procedures), tell your doctor or dentist about this medication and all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).
This drug is not recommended for use during pregnancy. It may harm an unborn baby. If you become pregnant or think you may be pregnant, inform your doctor immediately. To avoid pregnancy, both males and females using the drug must use reliable form(s) of birth control during treatment.
