Uses For Votrient
Pazopanib is an anticancer medicine that is used to treat adults with kidney cancer (advanced renal cell carcinoma). It is also used to treat advanced soft tissue sarcoma (STS) in patients who have received cancer treatments.
Pazopanib interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by pazopanib, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, like hair loss, may not be serious but may cause concern. Some effects may not occur for months or years after the medicine is used.
Before you begin treatment with pazopanib, you and your doctor should talk about the benefits this medicine will do as well as the risks of using it.
This medicine is available only with your doctor's prescription.
