Uses for Zirabev

Bevacizumab injection is given with other medicines to treat patients with metastatic (cancer that has spread) carcinoma of the colon or rectum. This medicine is also used to treat a certain type of metastatic lung cancer called nonsquamous, non-small cell lung cancer, and a certain type of brain tumor called glioblastoma that keeps coming back (recurrent).

Bevacizumab injection is also used in combination with other medicines (eg, interferon alfa) to treat patients with metastatic kidney cancer. It is also used in combination with other medicines (eg, paclitaxel and cisplatin, or paclitaxel and topotecan) to treat patients with cervical cancer that is continuing, keeps coming back, or has spread to other parts of the body. This medicine is also used in combination with other medicines (eg, paclitaxel, pegylated liposomal doxorubicin, topotecan, carboplatin and paclitaxel, or carboplatin and gemcitabine followed by Avastin® alone) to treat patients with platinum-resistant, recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer with or without having previous surgery.

Bevacizumab injection is also used together with atezolizumab to treat a type of liver cancer called hepatocellular carcinoma (HCC) that has spread throughout the body (metastatic) or cannot be removed by surgery (unresectable) in patients who have not received other cancer medicines by mouth or injection.

Bevacizumab is a substance that helps the body fight cancer. It prevents the growth of certain types of blood vessels to cancer cells. This helps to decrease the growth of cancer cells by starving the cells of nutrients that are needed to grow.

This medicine is to be given only by or under the immediate supervision of your doctor.

Proper use of Zirabev

Medicines used to treat cancer are very strong and can have many side effects. Before receiving this medicine, make sure you understand all the risks and benefits. It is important for you to work closely with your doctor during your treatment.

A nurse or other trained health professional will give you this medicine in a medical facility. It is given through a needle placed into one of your veins. It must be given slowly, so the needle will have to stay in place for at least 30 to 90 minutes every 2 or 3 weeks. Your doctor will decide how many treatments you will need.

Bevacizumab is often given together with other cancer medicines. If you are using a combination of medicines, make sure that you take each one at the proper time and do not mix them. Ask your doctor to help you plan a way to remember to take your medicines at the right times.

Precautions while using Zirabev

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood and urine tests are needed to check for unwanted effects. Be sure to keep all appointments. You may be taught how to check your blood pressure at home.

Receiving this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to prevent pregnancy while you are receiving this medicine and for at least 6 months after the last dose. If you think you have become pregnant while receiving this medicine, tell your doctor right away.

Using this medicine may increase risk of ovarian failure. Talk with your doctor if you plan to have children. Some women receiving this medicine have become infertile (unable to have children).

This medicine can cause stomach or bowel perforation (tear or hole), including blockage. Check with your doctor right away if you have severe stomach pain, constipation, fever, nausea, or vomiting.

This medicine may affect the way your body heals. Make sure any doctor who treats you knows that you are receiving this medicine. You may need to stop receiving it at least 28 days before or after having surgery and until the wound has healed enough.

Bevacizumab can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

• If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
• Check with your doctor right away if you start to cough up blood or if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
• Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
• Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
• Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
• Avoid contact sports or other situations where bruising or injury could occur.

This medicine may increase your chance of having bleeding problems. Tell your doctor right away if you start to notice any signs of bleeding.

This medicine may increase your chance of having blood clots or a brain condition called posterior reversible encephalopathy syndrome (PRES). Tell your doctor right away if you develop chest pain, sudden and severe headaches, fainting spells, seizures, unusual drowsiness, confusion, or problems with vision, speech, or walking while you are using this medicine.

Your blood pressure might get too high while you are receiving this medicine. This may cause headaches, dizziness, or blurred vision. You might need to measure your blood pressure at home. If you think your blood pressure is too high, call your doctor right away.

Check with your doctor right away if you have bloody urine, a decrease in frequency or amount of urine, an increase in blood pressure, increased thirst, loss of appetite, lower back or side pain, nausea, swelling of the face, fingers, or lower legs, trouble breathing, unusual tiredness or weakness, vomiting, or weight gain. These could be symptoms of a serious kidney problem.

Bevacizumab may cause infusion-related reactions, which can be life-threatening and require immediate medical attention.
