About This Drug
Bortezomib is used to treat cancer. It is given in the vein (IV) or by a shot under the skin (subcutaneously). If given every 3 days, it should be given no earlier than 72 hours from your last dose unless directed differently by your cancer doctor.
Possible Side Effects (More Common)
- Effects on the nerves are called peripheral neuropathy. You may feel numbness, tingling, or pain in your hands and feet. It may be hard for you to button your clothes, open jars, or walk as usual. The effect on the nerves may get worse with more doses of the drug. These effects get better in some people after the drug is stopped but it does not get better in all people.
- Bone marrow depression. This is a decrease in the number of white blood cells, red blood cells, and platelets. This may raise your risk of infection, make you tired and weak (fatigue), and raise your risk of bleeding.
- Feeling dizzy
- Nausea and throwing up (vomiting). These symptoms may happen within a few hours or many hours after your treatment and may last up to 72 hours. Medicines are available to stop or lessen these side effects.
- Constipation (not able to move bowels)
- Loose bowel movements (diarrhea) that may last for a few days
- Stomach pain
- Viral infections. Your doctor may prescribe a medicine to prevent certain viral infections while you are getting treated with bortezomib.
- Muscle cramps
- Decreased appetite (decreased hunger)
- Changes in the way food and drinks taste
- Skin rash
- In patients who take medicine for high blood sugar (diabetes), bortezomib may cause high or low blood sugars. Your doctor may tell you to check your blood sugar more often, and may change the dose of your diabetes medicine.
Possible Side Effects (Less Common)

Treating Side Effects
- If you have numbness and tingling in your hands and feet, be careful when cooking, walking, and handling sharp objects and hot liquids.
- Drink 6-8 cups of fluids each day unless your doctor has told you to limit your fluid intake due to some other health problem. A cup is 8 ounces of fluid. If you throw up or have loose bowel movements you should drink more fluids so that you do not become dehydrated (lack water in the body due to losing too much fluid).
- If you are dizzy, get up slowly after sitting or lying.

- Let your doctor or nurse know if you are having trouble sleeping.
When you tell a doctor or nurse your health history, always tell them that you have received bortezomib.
