Zirabev treats certain types of cancer. This medication is associated with ovarian failure that can mimic the symptoms of early menopause and decrease fertility.
Zirabev is a prescription medication used to treat colorectal cancer, lung cancer, renal cell cancer (a type of cancer that begins in the kidney), glioblastoma, and cervical cancer.
Zirabev is a biosimilar to bevacizumab (brand name Avastin), which belongs to a group of drugs called antiangiogenic agents. It inhibits the development of new blood vessels by recognizing and binding to a particular protein. This inhibits the growth and spread of tumors.
This medication comes in a liquid form and is injected intravenously (into a vein) by your healthcare provider. You will most likely receive an injection every 2 or 3 weeks.
Common side effects include nosebleeds, headache, and high blood pressure.

Zirabev may cause serious side effects.
Everyone reacts differently to Zirabev therapy, so it's important to know what the side effects are. Zirabev may cause serious side effects that can be life-threatening. Your doctor will stop treatment if any serious side effects occur. Be sure to contact your healthcare team if there are any signs of these side effects.
Most serious side effects (not common, but sometimes fatal):
- GI perforation. A hole that develops in your stomach or intestine. Symptoms include pain in your abdomen, nausea, vomiting, constipation, or fever
- Wounds that don't heal. A cut made during surgery can be slow to heal or may not fully heal. Zirabev should not be used for at least 28 days before or after surgery and until surgical wounds are fully healed
- Serious bleeding. This includes vomiting or coughing up blood; bleeding in the stomach, brain, or spinal cord; nosebleeds; and vaginal bleeding. If you recently coughed up blood or had serious bleeding, be sure to tell your doctor
Other possible serious side effects:
- Abnormal passage in the body. This type of passage—known as a fistula—is an irregular connection from one part of the body to another and can sometimes be fatal
- Severe high blood pressure. Blood pressure that severely spikes or shows signs of affecting the brain. Blood pressure should be monitored every 2 to 3 weeks while on Zirabev and after stopping treatment
- Kidney problems. These may be caused by too much protein in the urine and can sometimes be fatal
- Infusion-related reactions. These were uncommon with the first dose of bevacizumab (less than 3% of patients); 0.2% of patients had severe reactions. Infusion reactions include high blood pressure or severe high blood pressure that may lead to stroke, trouble breathing, decreased oxygen in red blood cells, a serious allergic reaction, chest pain, headache, tremors, and excessive sweating. Your doctor or nurse will monitor you for signs of infusion reactions
- Severe stroke or heart problems. These may include blood clots, mini-stroke, heart attack, chest pain, and your heart may become too weak to pump blood to other parts of your body (congestive heart failure). These can sometimes be fatal
- Nervous system and vision problems. Signs include headache, seizure, high blood pressure, sluggishness, confusion, and blindness
