bortezomib (Intravenous route, Subcutaneous route)
Pharmacologic Class: Proteasome Inhibitor
Uses For bortezomib
Bortezomib injection is used to treat multiple myeloma (blood plasma cell cancer) in patients with or without a prior 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.
bortezomib is to be given only by or under the 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 bortezomib, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to bortezomib or any other medicines. 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.
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).
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of bortezomib injection in the elderly. However, elderly patients are more sensitive to the effects of bortezomib than younger adults.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Proper Use of bortezomib
Medicines used to treat cancer are very strong and can have many side effects. Before receiving bortezomib, make sure you understand all the risks and benefits. It is important for you to work closely with your doctor during your treatment.
A nurse or other trained health professional will give you bortezomib in a hospital or cancer treatment center. bortezomib 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 bortezomib 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 bortezomib for multiple myeloma, it is important to tell your doctor if you have received bortezomib in the past.
Precautions While Using bortezomib
It is very important that your doctor check you at regular visits to make sure that bortezomib is working properly. Blood tests may be needed to check for unwanted effects.
Using bortezomib while you are pregnant can harm your unborn baby. Men and women should use an effective form of birth control during treatment and for at least 2 months after the last dose to keep from getting pregnant. If you think a pregnancy has occurred while receiving bortezomib, tell your doctor right away.
Tell your doctor right away if you are having burning, numbness, tingling, or painful sensations in the arms, hands, legs, or feet. These could be symptoms of a condition, called peripheral neuropathy.
Dizziness, lightheadedness, or even fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve dizziness or lightheadedness.
bortezomib may cause some people to become dizzy, drowsy, tired, or less alert than they are normally. Make sure you know how you react to bortezomib before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert.
bortezomib may cause serious heart problems. Tell your doctor right away if you have chest pain or discomfort, shortness of breath, irregular heartbeat, or swelling of the feet, ankles, or legs while you are receiving bortezomib.
Tell your doctor right away if you have a cough, trouble breathing, chest tightness, or any type of breathing problem with bortezomib. These could be symptoms of a serious lung problem.
bortezomib may increase your chance of having a brain condition, called posterior reversible encephalopathy syndrome (PRES). Check with your doctor right away if you start having headaches, seizures, extreme drowsiness, confusion, or problems with vision while you are receiving bortezomib.
bortezomib may cause nausea, vomiting, constipation, and diarrhea, so it is important to drink plenty of fluids. If you experience dizziness or lightheadedness, contact your doctor. These could be symptoms of dehydration (not enough water in your body).
Bortezomib can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:
- If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
- Check with your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
- Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
- Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
- Be careful not to cut yourself when you are using sharp objects, such as a safety razor or fingernail or toenail cutters.
- Avoid contact sports or other situations where bruising or injury could occur.
bortezomib may cause a serious reaction, called tumor lysis syndrome (TLS). Call your doctor right away if you have a change in how much or how often you urinate, muscle or joint pain, stiffness or swelling, lower back, side, or stomach pain, a rapid weight gain, swelling of the feet or lower legs, or unusual tiredness or weakness.
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.
If you are diabetic and you are taking an oral antidiabetic medicine, you should check your blood sugar level often and report any unusual changes to your doctor.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.
