If you’re taking oral fosfomycin (Monurol) for a UTI, there aren’t many food restrictions, but a few things are important:
- Avoid metoclopramide (Reglan) unless your doctor approves it. It can reduce fosfomycin levels and urinary concentrations, potentially making treatment less effective. Other medicines that speed up the stomach or intestines may have a similar effect.
- Don’t take the granules dry. Dissolve the entire prescribed packet in water and drink it promptly.
- Don’t take extra or repeat doses unless your prescriber specifically tells you to. For uncomplicated bladder infections, fosfomycin is commonly prescribed as a single 3-gram dose.
- Food does not need to be avoided.Fosfomycin can be taken with or without food, although food can reduce and delay absorption somewhat.
- If you develop severe, persistent, watery, or bloody diarrhea, don’t simply treat it yourself with anti-diarrhea medication—contact a healthcare professional, because antibiotics can occasionally cause serious antibiotic-associated diarrhea.
Also, contact your healthcare provider if your UTI symptoms aren’t improving within about 2–3 days, or if you develop fever, chills, vomiting, or pain in your back/side, which may suggest a more serious infection.
