Warnings and precautions
Before you take VOTRIENT your doctor needs to know:
- if you have heart disease

- if you have liver disease
- if you have problems with bleeding
- if you have gastrointestinal problems
- if you have thyroid problems
- if you are going to have a surgical or dental procedure, or if you have had either recently.
Check with your doctor if you think any of these may apply to you. You may need extra tests to check that your heart, liver, and thyroid are working properly. Your doctor may decide to adjust your dose or stop treatment based on the results of these tests.
Other medicines and VOTRIENT
Always tell your health care provider if you are taking any other medicine. (This includes all complementary or traditional medicines.) Some medicines may affect the way VOTRIENT works or VOTRIENT may affect how other medicines work. These include:

Tell your doctor if you are taking any of these. Grapefruit juice should be avoided when taking VOTRIENT, as this may increase concentration of the active ingredient i.e., pazopanib in your blood stream which can cause side effects.
VOTRIENT with food and drink VOTRIENT is affected by food intake (see How to take VOTRIENT). You should not drink grapefruit juice while you are being treated with VOTRIENT as this may increase the chance of side effects.
While you are taking VOTRIENT: While you are taking VOTRIENT your doctor will take blood samples to check for any liver problems or thyroid problems. Your doctor will also take blood and urine samples to check for any kidney problems. You will also have your blood pressure checked. Your doctor will periodically record your electrocardiogram (ECG) to check your heart’s electrical conduction. Your doctor will also check on any recent surgical or dental procedures to see if you are healing properly.
Pregnancy, breastfeeding and fertility
Use a reliable method of contraception to avoid becoming pregnant while you are taking VOTRIENT. VOTRIENT should not be taken if you are pregnant. Mothers should not breastfeed their babies while taking VOTRIENT.
