Precautions To Be Aware Of Before Taking This Medication
Activity related precautionsThis medication can lower your blood pressure and may cause fatigue, dizziness, light-headedness, fainting, double vision, or blurred vision. Use caution or avoid operating machinery, including driving a car, following treatment with this medication. If you are taking any medication(s) that lower your blood pressure, the dose of these medications may need to be adjusted by your doctor.
Blood related precautions
- This medication may temporarily reduce the number of platelets in your blood. This can increase your risk of bleeding. Contact your doctor or healthcare provider if you notice unusual bleeding or bruising, have black or tar-like stools, see blood in your urine, or develop pinpoint red spots on your skin. If your platelet levels become too low, your doctor or healthcare provider may recommend that your treatment be delayed, that you receive a platelet transfusion, and/or that you take medication to help increase the number of platelets in your blood. To lower your chance of bleeding, do not use aspirin, aspirin-containing medications, or aspirin-like medications(for example ibuprofen, naproxen). Use caution with sharp objects like razors and nail cutters, and avoid activities that can cause cuts, bumps, and bruises.
- This medication may temporarily lower the number of red cells in your blood. This can increase your risk of anemia. If your red blood cell level becomes low, you may feel tired and weak. If your red blood cell level becomes too low, your doctor or healthcare provider may recommend that your treatment be delayed, that you receive a red blood cell transfusion, and/or you receive a medication to help increase the red cells in your blood.
- Occasionally, this medication may temporarily reduce the number of germ fighting white blood cells in your blood. This can increase your risk of infection. Contact your doctor or healthcare provider promptly if you develop any signs of an infection such as fever, painful urination, chills, or a sore throat that doesn’t go away. If your white blood cell levels become too low, your doctor or healthcare provider may recommend that your treatment be delayed and/or you receive medication to increase the number of white cells in your blood. To lower your risk of infection, stay away from crowds and people with colds or other illnesses, wash your hands well and often, and brush and floss your teeth daily unless you have been told your platelets are low.
Gastrointestinal related precautionsThis medication may cause nausea, vomiting, and/or diarrhea which can lead to dehydration. Eat small frequent meals, bland foods (for example bananas, rice, apples, toast), and drink plenty of water and fluids that contain electrolytes (e.g. Gatorade, Pedialyte) to avoid dehydration. Contact your doctor or healthcare provider if you have moderate to severe nausea, vomiting or diarrhea. These side effects can be treated with medications.
Organ related precautions
- Rarely, this medication can cause heart problems, including congestive heart failure. Your doctor or healthcare provider will check your heart regularly while you are on this medication to make sure that your heart is working properly. If you have any problems with your heart before starting this medication, make sure that you tell your doctor or healthcare provider so that he or she can watch you carefully for possible problems or side effects.
- This medication is broken down by enzymes (chemicals) in the liver and cleared from the body. In patients with severe liver disease, bortezomib may not break down normally which can lead to high levels of this medication in the body and a greater chance of side effects. If you have any liver problems before starting this medication, make sure that you tell your doctor or healthcare provider so that he or she can watch you carefully for possible problems or side effects.
- Rarely, this medication can cause changes in the ability of your liver and/or kidneys to work normally. Your doctor or healthcare provider will check your liver and kidneys regularly, usually through blood tests, while you are on this medication to make sure that they are both working properly. If you have any liver or kidney problems before starting this medication, make sure that you tell your doctor or healthcare provider so that he or she can watch you carefully for possible problems or side effects.
- This medication can cause nerve problems in the hands and feet. Symptoms can include numbness, pain or a burning feeling in the feet or hands. Contact your doctor or healthcare provider if you experience new symptoms or if your symptoms get worse.
- Rarely, this medication can cause tumor lysis syndrome (TLS). This occurs when chemotherapy medications rapidly kill large numbers of cancer cells and cause abnormal changes in your blood. Your doctor or healthcare provider will check your blood regularly through blood tests. In addition, if you experience symptoms such as muscle weakness, tingling on the lips, arms or legs, anxiety, cough, wheezing, chest tightness (shortness of breath), fatigue, increased nausea and/or vomiting, joint-pain, or a feeling of general discomfort, you should contact your doctor or healthcare provider.
