Who manufactures Cytoxan (cyclophosphamide)?

Cytoxan is a brand name for the chemotherapy drug cyclophosphamide. It is made by multiple manufacturers, depending on the country and the specific product/strength available.

In the U.S., cyclophosphamide is sold under the Cytoxan brand by Pfizer [1].

Why you might see different “makers” for the same drug

Even when the active ingredient is the same (cyclophosphamide), the package labeling can differ:
- Branded product (Cytoxan): typically tied to the original brand manufacturer (Pfizer in the U.S.) [1].
- Generic cyclophosphamide: produced by different companies licensed to make the generic drug, which can change over time [2].

What to check on the label to identify the maker

The manufacturer name is usually listed on:
- the outer carton and/or
- the pharmacy label or medication insert.

If you tell me your country (and, if you can, the label manufacturer name from the box), I can help confirm who makes that specific product.
