Fosfomycin other name?

What is fosfomycin’s other name?

Fosfomycin is also known as phosphonomycin. It’s the alternative (older/chemical) name used for the same antibiotic.

What names do you see on prescriptions or packaging?

Depending on the salt form, fosfomycin products may be labeled with the specific formulation, such as:
- Fosfomycin trometamol (often written as “fosfomycin tromethamine” in some regions)

Is “fosfomycin” the same as “phosphonomycin”?

Yes. Phosphonomycin refers to fosfomycin. The difference you’ll see in practice is usually the formulation (for example, trometamol) rather than a different drug.
