3 Proper Usage
Proper usage of Ifex requires strict adherence to your doctor’s orders.
Ifosfamide injection is given by a doctor, nurse or other trained health professional in a hospital or cancer treatment centers. It is given through a needle placed into a vein (intravenous or IV route). The IV tube stays in place for 30 minutes because Ifosfamide must be injected slowly.
Ifosfamide injections are given on a schedule. Ifosfamide is usually given for five consecutive days, and given every 3 weeks or when your body can tolerate the medication.
Ifosfamide injections are often given with other medications. Maintain good communication with your doctor if you are prescribed with a combination of medicines.
Always make sure you take them at the proper time and avoid mixing them. Make sure to ask your doctor for help so you can better remember taking your medications at the right times.
Ifosfamide is highly irritating to the kidneys and bladder. It is very important that you drink extra fluids so you will pass out more urine and avoid buildup of the drug in the urinary tract. Always make sure to empty your bladder frequently, including at least once during the night.
Urinating frequently can avoid Ifosfamide from causing kidney or bladder problems. Follow your doctor’s instructions on your fluid intake requirements per day.
Ifosfamide can make you feel ill because it causes nausea and vomiting as side effects. However, it is still important that you still have to continue taking Ifosfamide even if you feel ill. For help on side effects, ask your doctor.

Avoid persons with infections or who are visibly ill. If you think you have infection call your doctor immediately, especially if you have a fever, chills, cough, hoarse voice, lower back pain, pain in the flanks, painful or difficulties in urinating.
Call your doctor if you have signs and symptoms of bleeding, such as having black tarry stools, blood in urine or stool, having pinpoint red or purple spots on the skin, and unusual bleeding or bruising.

Call your doctor or dentist for other ways to clean your teeth and gums. Also, call your doctor first before having any dental work done.
Wash your hands regularly and often use alcohol-based hand sanitizer to avoid infections. Avoid touching your eyes and insides of your nose, and refrain from touching surfaces.
