This drug may also be used for certain serious eye conditions (such as age-related macular degeneration, macular edema).

How to use

This medication is given by infusion into a vein by a health care professional. The first dose is usually given over 90 minutes. If you tolerate the first dose well, then later infusions may be given over a shorter time (60 or 30 minutes).

Infusion reactions may happen while you are receiving this medication. Tell your health care professional right away if you have symptoms such as difficulty breathing, flushing, severe dizziness, nausea/vomiting, shaking, or chest pain. Your health care professional will monitor you closely during your infusion. Your infusion may be slowed down or stopped depending on your symptoms.

The dosage is based on your medical condition, weight, and response to treatment.

Use this medication regularly to get the most benefit from it. To help you remember, mark the days on the calendar when you need to receive the medication.

Side effects

Dry mouth, cough, voice changes, loss of appetite, diarrhea, vomiting, constipation, mouth sores, nausea, or headache may occur. If any of these effects last or get worse, tell your doctor or pharmacist right away.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including:

  • fast heartbeat
  • symptoms of heart failure (such as swelling ankles/feet, unusual tiredness, unusual/sudden weight gain)

  • muscle cramps
  • muscle loss
  • yellowing eyes/skin
  • dark urine

This medication may raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are high. Your doctor may control your blood pressure with medication.

Bevacizumab may rarely cause blood clots (such as pulmonary embolism, stroke, heart attack, deep vein thrombosis). You may be at increased risk for blood clots if you have a history of blood clots, heart/blood vessel disease, or if you are immobile (such as on very long plane flights or being bedridden). If you use estrogen-containing products, these may also increase your risk. Before using this medication, if you have any of these conditions report them to your doctor or pharmacist. Get medical help right away if any of these side effects occur:

  • shortness of breath/rapid breathing
  • chest/jaw/left arm pain
  • unusual sweating
  • confusion
  • sudden dizziness/fainting
  • pain/swelling/warmth in groin/calf
  • sudden/severe headaches

This medication can cause bleeding. Some episodes may be minor including nosebleeds, minor gum bleeding, and vaginal bleeding. If these last or get worse, tell your doctor or pharmacist promptly.

This medication can also cause serious (possibly fatal) bleeding, such as bleeding from the stomach/intestines or in the brain. You should not receive this medication if you have any serious bleeding problems. In addition, this medication can rarely cause a tear in the stomach/intestines (gastrointestinal perforation). Get medical help right away if you have any signs of these serious side effects, including stomach/abdominal pain that is severe or doesn't go away, bloody or black/tarry stools, constipation with vomiting, vomit that is bloody or looks like coffee grounds, coughing up blood, shortness of breath, dizziness/fainting, unusual tiredness/weakness, severe headache, sudden/severe back pain, fever.

This medication may also cause wounds to heal slowly or poorly or cause the wounds to break open. It can also rarely cause very serious (possibly fatal) skin and tissue infections that spread quickly. Get medical help right away if you have wounds that are not healing well, a fever, severe pain/redness/heat/swelling at the surgery site or other areas on the skin, fluid-filled blisters in the skin, discolored/scaling/peeling skin, confusion, dizziness, or fainting. You should not receive this medication for at least 4 weeks before and after a major surgery and until the wound from the surgery is fully healed.
