Monitoring Side Effects
Find the most common side effects of VELCADE.
Contact the doctor if your loved one is experiencing any side effects because they may suggest medications, therapies, or other ways to help relieve or lessen side effects, including changes to your loved one’s treatment plan. Some common side effects associated with VELCADE® (bortezomib) are described below. Please talk to your loved one’s doctor or nurse about the signs and symptoms to be aware of and when to call for advice.
Common Side Effects of VELCADE
Fatigue, malaise, and weakness may be experienced during treatment.
Nausea, diarrhea, constipation, and vomiting are generally mild to moderate. Anorexia or decreased appetite is a condition resulting from the side effects.
Low platelet, neutrophils, and red blood cell counts may temporarily occur during treatment with VELCADE. Platelets are blood cells that help blood to clot, neutrophils are blood cells that help fight infection, and red blood cells are oxygen-carrying cells. Low platelet counts cause an increased risk of bruising and bleeding, and low neutrophil counts cause an increased risk of infection. Both platelets and neutrophils generally return toward their baseline levels during the 10 days between cycles (the rest period). A low red blood cell count is called anemia, which may lead to fatigue and shortness of breath.
Tingling, numbness in the hands, arms, feet, or legs – commonly known as peripheral neuropathy can progress to discomfort, pain, weakness, or a burning sensation, which in some cases can be severe. These symptoms should be reported to the patient’s doctor or nurse immediately; they can help you and your loved one manage these symptoms. The dose of VELCADE may need to be changed, or treatment interrupted, until the symptoms get better. Should the symptoms improve, the doctor may decide to continue VELCADE at a lower dose. The doctor may also suggest medications or therapies to help relieve or lessen these symptoms.
Even if the symptoms are easy to live with at first, it is important to let the doctor know as soon as the patient experiences any of them or if their existing neuropathy becomes worse. By catching peripheral neuropathy early, the physician may be able to manage it so your loved one can continue on therapy.
Fever may occur after VELCADE is administered, even after your loved one goes home from the doctor visit.
Low blood pressure may also occur during treatment with VELCADE. If the patient experiences a reduction in blood pressure, the doctor may adjust his or her medications or recommend increasing fluid intake. If your loved one has experienced a sudden drop in blood pressure, dizziness, or fainting, he or she should not drive or operate machinery.
Herpes zoster (a painful, itchy rash usually located in an area on one side of the body) may develop while a patient is on VELCADE. In the clinical trials for VELCADE, patients receiving VELCADE demonstrated an increased risk of developing this rash compared to those not on VELCADE. In addition, patients with multiple myeloma are at an increased risk for developing herpes zoster related to their decreased immune system function. The doctor will discuss with you and your loved one the option of taking an antiviral medication to help decrease the risk of him or her developing this condition.
Heart problems. VELCADE treatment can cause or worsen heart rhythm problems and heart failure. Your loved one’s doctor may closely monitor them if they have, or are at risk for, heart disease. Tell their doctor if they experience chest pressure or pain, palpitations, swelling in their hands, ankles, or feet (peripheral edema), or shortness of breath.
Lung disorders. There have been reports of lung disorders in patients receiving VELCADE. Some of these events have been fatal. Tell your loved one’s doctor if they experience any cough, shortness of breath (dyspnea), wheezing, or difficulty breathing.
Liver disease. If your loved one has liver problems, it can be harder for their body to get rid of VELCADE. VELCADE has caused sudden liver failure in patients who were taking many medications or had other serious medical conditions. Symptoms of liver problems include a yellow discoloration of the eyes and skin (jaundice) and changes in liver enzymes measured in blood tests. Your loved one’s doctor will closely monitor them if they have liver disease.
When Should I Contact the Doctor During Treatment?
You should call the doctor or nurse if you want to discuss any aspect of your loved one’s treatment or have any questions. Be sure to advise the doctor of medications your loved one may be currently taking, including over-the-counter medications and herbal products.
Because they are a trained professional, they can help you and your loved one. Your doctor may prescribe medicines to alleviate or stop the side effect. He or she may decide to lower the dose of VELCADE or instruct your loved one to stop taking VELCADE altogether.

VELCADE Dose Modification
Before starting each VELCADE cycle, the doctor will carefully evaluate blood and urine tests to monitor the effect of the medication on your body. If he or she is having any side effects, it may be necessary to change the dose of VELCADE, temporarily stop his or her treatment, change your infusion schedule, or discontinue VELCADE. In clinical trials, 15 to 25% of patients stopped VELCADE treatment due to side effects.
It is important that you continue your treatment as long as you and your doctor agree that it is in your best interest. Once your prescribed course of therapy is complete, the doctor will discontinue treatment.
