Injectable

• 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.
• An intravenous (in-tra-VEEN-us) or IV injection is given through a tube put in one of your veins, usually in your arm, wrist, hand, or sometimes in your chest.
• This medicine is sometimes given as a direct injection into your chest or abdomen.
• You may get your treatments at a clinic or hospital because the IV must be given as soon as medicine powder has been mixed with liquid.
• Drink 8 to 12 full glasses of liquids daily while you are being treated with this medicine.
