Uses for bortezomib

Bortezomib injection is used to treat multiple myeloma (blood plasma cell cancer) in patients with or without a previous history of treatment, and mantle cell lymphoma.

Bortezomib is an antineoplastic agent (cancer medicine). It interferes with the growth of cancer cells, which are eventually destroyed by the body. Since the growth of normal body cells may also be affected by bortezomib, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, such as a skin rash, may not be serious but may cause concern. Some effects may not occur until months or years after the medicine is used.

This medicine is to be given only by or under the direct supervision of your doctor.

Before using bortezomib

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of bortezomib injection in the pediatric population. Safety and efficacy have not been established in children with relapsed acute lymphoblastic leukemia (ALL).

Geriatric

A nurse or other trained health professional will give you this medicine in a medical facility. It is given through a needle placed into one of your veins or as a shot under your skin (usually in the abdomen or thighs).

You may receive medicines to help prevent nausea, vomiting, or diarrhea. Drink extra fluids while you are using this medicine to keep from getting dehydrated. This could also help you avoid feeling dizzy or lightheaded. You may also receive medicines (eg, dexamethasone, melphalan, prednisone, antivirals) to help prevent unwanted reactions to the injection and decrease the risk of virus infection (eg, herpes zoster) reactivation.

If you are using this medicine for multiple myeloma, it is important to tell your doctor if you have received bortezomib in the past.

Bortezomib can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.
