Bevacizumab side effects are usually minor and do not present any specific health concerns, although any bothersome symptoms should always be reported to a doctor for further medical evaluation. The most common bevacizumab side effects include gastrointestinal disturbances, dry skin, and headaches. Some patients may also experience nosebleeds, loss of appetite, or sores in the mouth. Some of the more serious potential side effects include extreme dizziness, abnormal vaginal bleeding, or a potentially fatal allergic reaction known as anaphylaxis. Any questions or concerns about individualized bevacizumab side effects should be discussed with a doctor or other medical professional.
Gastrointestinal disturbances are frequently reported as bevacizumab side effects and may be treated with the use of additional medications. Mild to moderate nausea, lack of appetite, or weight loss are relatively common while taking this medication and may lessen as the body adjusts to the drug. Constipation, diarrhea, or dehydration may occur as a result of using this medication. If these symptoms are persistent or become especially troubling, a doctor should be notified.
Dry skin and hair have been reported as possible bevacizumab side effects. In some cases, mild hair loss may occur as well. Headaches commonly occur with this medication, but a doctor should be consulted if the headache occurs suddenly or if it becomes exceptionally painful. Mood changes, blurred vision, or the development of skin lesions should be evaluated by the medical staff to make sure there are no serious complications involving the use of this medication.
Menstrual changes such as abnormal bleeding or discharge may occur as potential bevacizumab side effects. This could indicate the presence of a severe complication and should be reported to a doctor right away. Extreme levels of fatigue, dizziness, or weakness should be evaluated by the medical staff. If breathing becomes difficult or if the heart rate dramatically changes, emergency medical assistance is essential.
A severe and potentially life-threatening allergic reaction known as anaphylaxis may occur when taking bevacizumab, even if this medication has been well tolerated in the past. Symptoms may include itching; hives; or swelling of the face, lips, or tongue. The throat may begin to swell, causing breathing to become difficult or even impossible. Permanent brain damage or even death can occur within a matter of minutes if proper medical attention is not given. For this reason, any possible signs of an allergic reaction should always be treated as a medical emergency.
