Why is this medication prescribed?

Bevacizumab injection products are used in conjunction with other chemotherapy drugs to treat specific types of cancer that start in the large intestine and colon, non-small cell lung cancer (NSCLC), glioblastoma (a specific kind of brain tumor), renal cell cancer (RCC), cervical cancer (a cancer that starts in the opening of the uterus [womb]), ovarian (the female reproductive organs where the eggs are formed), fallopian tube (the tube that carries the eggs released by the ovaries to the uterus), or peritoneal (a layer of tissue lining the abdomen) cancer.Additionally, atezolizumab (Tecentriq) and bevacizumab (Avastin) are used in tandem to treat hepatocellular carcinoma (HCC) that has spread or is not surgically resectable.

In patients who have not previously had chemotherapy, bevacizumab (Avastin) and atezolizumab (Tecentriq) are also used in conjunction to treat hepatocellular carcinoma (HCC) that has spread or cannot be removed surgically. Bevacizumab injection products are in a class of medications called antiangiogenic agents. They work by stopping the formation of blood vessels that bring oxygen and nutrients to tumors. This may slow the growth and spread of tumors.

How should this medicine be used?

Bevacizumab injection is typically administered by a healthcare professional in a clinical setting, such as a hospital or doctor’s office. The specific dosage and administration schedule depend on various factors, including the type of cancer being treated, the patient’s overall health, and other medications they may be taking.

Here are some general guidelines for the use of Bevacizumab injection:

  • Administration: Bevacizumab is usually given as an intravenous infusion, which means it is injected directly into a vein. The infusion is typically delivered over a period of time, often ranging from 30 minutes to several hours. The healthcare provider will determine the appropriate infusion rate based on the patient’s condition and tolerance.
  • Dosage: The dosage of Bevacizumab can vary depending on factors such as the type of cancer being treated and the patient’s body weight. It is important to follow the prescribing doctor’s instructions regarding the dosage and schedule of administration.
  • Frequency: Bevacizumab is often administered on a regular schedule, such as once every two or three weeks. The frequency of treatment may vary depending on the specific treatment regimen prescribed by the doctor.
  • Monitoring: During treatment with Bevacizumab, patients will typically undergo regular monitoring to assess their response to therapy and monitor for any potential side effects. This may involve blood tests, imaging studies, and physical examinations.
  • Duration: The duration of treatment with Bevacizumab can vary depending on factors such as the type and stage of cancer, the patient’s response to therapy, and other treatment modalities being used. Some patients may receive Bevacizumab for a limited course of treatment, while others may continue treatment for a longer period of time.

It’s important for patients to communicate openly with their healthcare providers throughout the course of treatment, reporting any side effects or concerns they may experience. Additionally, patients should follow any additional instructions provided by their doctor regarding pre-treatment preparations or post-treatment care.

Other uses for this medicine

In addition to its primary use in treating various types of cancer, Bevacizumab injection may also be used in certain other medical conditions, although such uses would be prescribed off-label and should be discussed thoroughly with a healthcare provider. Off-label use might include conditions like age-related macular degeneration (AMD), diabetic retinopathy, and macular edema.

What special precautions should I follow?

Special precautions should be observed when using Bevacizumab injection due to its potential for serious side effects and interactions with other medications. Here are some important precautions to consider:

  • Immunizations: Live vaccines should not be administered during treatment with Bevacizumab due to the risk of infection. Inactivated vaccines may be less effective during treatment.

It’s crucial for patients to discuss their medical history, including any existing health conditions and medications they are taking, with their healthcare provider before starting treatment with Bevacizumab. Open communication and close monitoring can help mitigate risks and ensure safe and effective treatment.
