• This medicine, like all medicines used to treat cancer, is very strong. Make sure you understand why you are getting it and what the risks and benefits of treatment are. It is important for you to work closely with your doctor.
• Your doctor will decide how much medicine you should have and when it will be given. A nurse or other caregiver trained to give cancer drugs will give your treatment.
• Your medicine will be given into a vein, usually in your arm, wrist, or hand, and sometimes in your chest. This is called intravenous (in-tra-VEEN-us), or IV.
• Do not get the medicine on your skin. If it does, wash the area well with soap and water, and tell your caregiver.
