Drug Interaction Report

Using radium Ra 223 dichloride together with PAZOPanib may increase the risk of side effects that affect your bone marrow function, resulting in low numbers of different types of blood cells. You may be more likely to develop anemia, bleeding problems, or infections due to low blood cell counts. You should seek medical attention if you develop paleness, fatigue, dizziness, fainting, unusual bruising or bleeding, fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, and pain or burning during urination. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Do not consume grapefruit or grapefruit juice during treatment with PAZOPanib unless directed otherwise by your doctor. Grapefruit juice can increase the blood levels of PAZOPanib, which may lead to an increased risk of serious side effects such as liver damage, irregular heart rhythm, bleeding, high blood pressure, heart attack, and stroke. Taking PAZOPanib with food can also significantly increase its absorption and levels in the blood. Therefore, you should take PAZOPanib on an empty stomach, at least one hour before or two hours after eating. Call your doctor immediately if you develop fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. You should also seek immediate medical attention if you experience signs and symptoms that could indicate cardiovascular problems such as sudden dizziness; lightheadedness; fainting; fast or pounding heartbeats; chest pain or tightness; pain in your arms, back, neck, or jaw; shortness of breath; numbness or weakness on one side of your body; and slurred speech or difficulty speaking. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
