Why is this medication prescribed?

Bortezomib is a medication used primarily in the treatment of multiple myeloma, a type of cancer that affects plasma cells in the bone marrow. It’s also used to treat mantle cell lymphoma, another type of cancer that affects the lymphatic system. Bortezomib is classified as a proteasome inhibitor, which means it works by blocking the action of proteasomes, enzymes that break down proteins within cells. By inhibiting proteasomes, bortezomib disrupts the growth and survival of cancer cells.

How should this medicine be used?

The dosage and administration of bortezomib can vary depending on the specific condition being treated, as well as other factors such as the patient’s overall health and response to treatment. Generally, it’s administered as an injection into a vein (intravenous infusion) or as a subcutaneous injection (injected under the skin).

The exact dosing schedule and duration of treatment will be determined by a healthcare provider, but typically, bortezomib is given in cycles, with rest periods in between to allow the body to recover from any side effects. It’s crucial to follow your healthcare provider’s instructions carefully and not to change the dose or schedule without consulting them first.

Additionally, bortezomib is often used in combination with other medications as part of a comprehensive treatment plan for multiple myeloma or mantle cell lymphoma. Your healthcare provider will determine the most appropriate combination of medications based on your individual situation.

As with any medication, it’s essential to be aware of potential side effects and to report any unusual symptoms to your healthcare provider promptly. They can help manage any side effects and adjust your treatment plan as needed.

Other uses for this medicine

Bortezomib is primarily used in the treatment of multiple myeloma and mantle cell lymphoma, as I mentioned earlier. However, researchers have explored its potential use in other types of cancer and conditions as well. Some studies have investigated its effectiveness in treating other hematologic malignancies (cancers of the blood, bone marrow, and lymph nodes) and solid tumors. These studies are ongoing, and bortezomib’s use in these other conditions may evolve as more research becomes available.

What special precautions should I follow?

As for special precautions when using bortezomib, here are some key points to keep in mind:

  • Pregnancy and breastfeeding: Bortezomib can harm an unborn baby if used during pregnancy. Therefore, it’s essential to use effective birth control during treatment and for a period after the last dose. If you become pregnant while using bortezomib, notify your healthcare provider immediately. It’s also not recommended to breastfeed while using bortezomib.
  • Liver and kidney function: Bortezomib is primarily metabolized by the liver and eliminated through the kidneys. Patients with impaired liver or kidney function may require dose adjustments or closer monitoring while using bortezomib. Your healthcare provider will assess your liver and kidney function before starting treatment and periodically during treatment.
  • Peripheral neuropathy: Bortezomib can cause peripheral neuropathy, which is a type of nerve damage that can lead to symptoms such as numbness, tingling, burning sensation, or weakness in the hands and feet. It’s essential to report any new or worsening neuropathy symptoms to your healthcare provider, as they may need to adjust your treatment or provide supportive care.
  • Blood cell counts: Bortezomib can affect the production of blood cells in the bone marrow, leading to low blood cell counts. Your healthcare provider will monitor your blood cell counts regularly during treatment and may adjust your dose or schedule if necessary.
  • Drug interactions: Bortezomib may interact with other medications, potentially affecting their effectiveness or increasing the risk of side effects. It’s essential to inform your healthcare provider about all the medications, supplements, and herbal products you are taking before starting bortezomib treatment.
  • Injection site reactions: If you are receiving bortezomib via subcutaneous injection, be aware of possible injection site reactions such as pain, redness, swelling, or irritation. Rotate injection sites as directed and notify your healthcare provider if you experience any persistent or severe injection site reactions.

These are some general precautions associated with bortezomib use, but it’s crucial to follow your healthcare provider’s specific instructions and guidance for your individual situation. They will provide personalized care and monitoring to help ensure the safest and most effective treatment possible.

What special dietary instructions should I follow?

Regarding dietary instructions, there are no specific dietary restrictions associated with bortezomib use. However, maintaining a balanced diet and staying well-hydrated can support overall health during treatment. Some individuals may experience nausea or digestive issues as side effects, so eating smaller, more frequent meals and avoiding spicy or heavy foods may be helpful.

What should I do if I forget a dose?

If you forget a dose of bortezomib, contact your healthcare provider or treatment team for guidance. They will advise you on whether to take the missed dose or adjust your treatment schedule. It’s essential not to double the dose to make up for a missed one unless instructed to do so by your healthcare provider. Consistency in following the prescribed dosing schedule is crucial for optimal treatment effectiveness.

What side effects can this medication cause?

Bortezomib, like many medications, can cause side effects, which can vary in severity from person to person. Some common side effects of bortezomib include:

  • Nausea and vomiting: Many people experience nausea and may vomit during bortezomib treatment. Medications to manage nausea may be prescribed to help alleviate these symptoms.
  • Peripheral neuropathy: Bortezomib can cause damage to the nerves, leading to symptoms such as numbness, tingling, burning sensation, or weakness in the hands and feet. This side effect can be dose-limiting and may require dose adjustments or supportive care.
  • Fatigue: Feeling tired or fatigued is a common side effect of bortezomib treatment. Adequate rest and managing activities may help alleviate fatigue.
  • Diarrhea or constipation: Bortezomib can affect the digestive system, leading to changes in bowel habits such as diarrhea or constipation. Drinking plenty of fluids and eating a high-fiber diet can help manage these symptoms.
  • Low blood cell counts: Bortezomib can decrease the production of blood cells in the bone marrow, leading to low levels of red blood cells (anemia), white blood cells (neutropenia), and platelets (thrombocytopenia). This can increase the risk of infections, bleeding, and fatigue.
  • Fever: Some people may experience fever or chills during or shortly after receiving bortezomib infusions.
  • Loss of appetite: Bortezomib treatment may cause a decreased appetite, leading to weight loss or malnutrition. Eating smaller, more frequent meals and incorporating nutrient-rich foods can help maintain adequate nutrition.
  • Joint pain: Bortezomib can cause joint pain or muscle aches in some individuals.
  • Rash or skin reactions: Skin reactions such as rash or itching may occur with bortezomib treatment.
  • Injection site reactions: If bortezomib is administered as a subcutaneous injection, redness, swelling, or pain at the injection site may occur.

It’s essential to report any side effects or symptoms experienced during bortezomib treatment to your healthcare provider. They can provide guidance on managing side effects and may adjust your treatment regimen if necessary to minimize discomfort and optimize your overall care.

What should I know about storage and disposal of this medication?

When it comes to storage and disposal of bortezomib:


  • Bortezomib should be stored at room temperature, ideally between 68°F to 77°F (20°C to 25°C).
  • It should be kept in its original packaging and protected from light.
  • Avoid storing bortezomib in the bathroom or other areas with high humidity or temperature fluctuations.
