Take the missed oral dose as soon as you remember. If it is almost time for the next dose, skip the dose you missed and take only the next regularly scheduled dose as directed. Do not take a double dose of this medication.
Contact your doctor if you miss a dose of cyclophosphamide injection.
What happens if I overdose (Cytoxan)?
Seek emergency medical attention.
Symptoms of a cyclophosphamide overdose may include decreased bone marrow function, infection, and heart problems.
What should I avoid while taking cyclophosphamide (Cytoxan)?
Cyclophosphamide can lower the activity of the immune system making you more susceptible to infection. Avoid contact with people who have colds, the flu, or other contagious illnesses. In addition, do not receive vaccines that contain a live strain of the virus (e.g., live oral polio vaccine) and avoid contact with individuals who have recently been vaccinated with a live virus.
What other drugs will affect cyclophosphamide (Cytoxan)?
Before taking cyclophosphamide, tell your doctor if you are taking any other medicines, especially any of the following:
- phenobarbital (Luminal, Solfoton);
- allopurinol (Zyloprim);
- digoxin (Lanoxin);
- warfarin (Coumadin);
- a thiazide diuretic (water pill) such as chlorothiazide (Diuril), hydrochlorothiazide (HCTZ, HydroDiuril, Esidrix, Microzide, Oretic), chlorthalidone (Hygroton, Thalitone), indapamide (Lozol), metolazone (Mykrox, Zaroxolyn), and others; or
- another chemotherapy medicine.
You may require a dosage adjustment or special monitoring during treatment if you are taking any of the medicines listed above.
Do not receive "live" vaccines during treatment with cyclophosphamide. Administration of a live vaccine may be dangerous during treatment with cyclophosphamide.
Other drugs may interact with cyclophosphamide. Talk to your doctor and pharmacist before taking any other prescription or over-the-counter medicines, including herbal products, during treatment with cyclophosphamide.
