  • have a low level of white blood cells or platelets (detected by blood tests);
  • have bone marrow problems;
  • have been previously treated with x-ray therapy;

  • have had your adrenal glands removed;
  • need to have surgery;
  • have any unhealed wounds;
  • have a history of heart disease;
  • have liver disease; or

You may not be able to take cyclophosphamide, or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.

Cyclophosphamide is in the FDA pregnancy category D. This means that cyclophosphamide is known to be harmful to an unborn baby. Cyclophosphamide may also affect egg production in women and sperm production in men. Do not take cyclophosphamide without first talking to your doctor if you are pregnant or could become pregnant during treatment. Use of cyclophosphamide by the father prior to conception has also been associated with birth defects. Contraceptive measures are recommended during treatment with cyclophosphamide for both men and women.

Cyclophosphamide passes into breast milk and may harm a nursing infant. Do not take cyclophosphamide without first talking to your doctor if you are breast feeding a baby.

How should I take cyclophosphamide (Cytoxan)?

Take cyclophosphamide exactly as directed by your doctor. If you do not understand these instructions, ask your doctor, nurse or pharmacist to explain them to you.

Take each oral dose with a large glass of water.

To avoid urinary bladder irritation during treatment with either oral or injectable cyclophosphamide, drink plenty of fluid during treatment and for 48 hours following treatment, usually 7 to 12 cups (3 quarts) per day, and empty your bladder frequently, every 2 to 3 hours including once during the night.

Taking oral cyclophosphamide on an empty stomach is preferable. If severe stomach upset occurs, take cyclophosphamide with food. Continue to take cyclophosphamide even if nausea and vomiting occurs. Do not stop taking the medicine without first talking to your doctor. Check with your doctor if vomiting occurs shortly after taking a dose of cyclophosphamide. Your doctor may want you to take another dose, but do not do this without checking with your doctor first.

If you are taking a liquid form of cyclophosphamide by mouth, use a dose measuring spoon or cup to ensure that you get the correct dose.

Injectable cyclophosphamide should only be administered under the supervision of a qualified healthcare provider experienced in the use of cancer chemotherapeutic agents.

Your doctor will determine the correct amount and frequency of treatment with cyclophosphamide depending upon the type of cancer being treated and other factors. Talk to your doctor if you have any questions or concerns regarding the treatment schedule.

Your doctor will probably want you to have regularly scheduled blood tests and other medical evaluations during treatment with cyclophosphamide to monitor progress and side effects.

Store cyclophosphamide oral tablets at or below 77 degrees Fahrenheit (25 degrees Celsius). Brief exposures to 86 degrees Fahrenheit (30 degrees Celsius) are permitted but the tablets should be protected from temperatures above 86 degrees Fahrenheit. Your healthcare provider will store cyclophosphamide injection as directed by the manufacturer. If you are storing cyclophosphamide injection at home, follow the directions provided by your healthcare provider.

Store cyclophosphamide oral liquid in a glass container in the refrigerator for up to 14 days.
