Cyclophosphamide comes in two forms: a tablet that is taken by mouth and an injection given through an IV. Some people will take cyclophosphamide every day, while others take it intermittently.
Try to take cyclophosphamide tablets on an empty stomach if possible. If the medicine upsets your stomach too much, try taking it with food.
Generally, it is best to take cyclophosphamide tablets in the morning or afternoon. Taking them at night may increase your risk of bladder damage. Your healthcare provider may also recommend drinking large amounts of water to flush your bladder out and protect it from damage.
For the injectable form, most people receive their cyclophosphamide injection at their healthcare provider's office, a hospital, or at an "infusion center."
For the medication to work properly, it must be taken as prescribed. Cyclophosphamide will not work as well if you stop taking it before your healthcare provider recommends.
If you are unsure about anything related to your dosage or cyclophosphamide dosing in general, talk with your healthcare provider, nurse, or pharmacist.
