Cytoxan manufacturer?

Who manufactures Cytoxan (cyclophosphamide)?

Cytoxan is a brand of the chemotherapy drug cyclophosphamide. In the U.S., the brand product is marketed by Pfizer (Pfizer Labs) and supplied under the Cytoxan name. [1]

Is Cytoxan made by other companies too (generic cyclophosphamide)?

Yes. Cyclophosphamide is widely available as generic versions from multiple manufacturers, depending on the dosage form and strength. These products use the same active ingredient (cyclophosphamide) but come from different companies. [2]

Which company makes the specific Cytoxan product I have?

The manufacturer can vary by packaging and strength. To identify the exact manufacturer for your bottle/box, check the label fields such as “Manufacturer,” “Distributed by,” or the “NDC” (National Drug Code) number listed on the prescription label. [2]

Where can I verify the manufacturer quickly?

You can verify by looking up the NDC for the specific product strength on:
- the package labeling (often includes manufacturer/distributor), or
- the prescribing information and drug listing pages for that exact NDC. [2]
