Answer

Although food and vitamin supplements that are rich in phosphorus and magnesium are advisable, remember that magnesium (and other divalent cations) can chelate fluoroquinolones, preventing their absorption from the gut.

Acidifying agents have been used. Ascorbic acid does not significantly decrease urinary pH, and ammonium chloride provides only temporary acidification. This approach is of little clinical usefulness. Urease inhibitors are effective in reducing stone formation, but long-term use is fraught with neurosensory, hematologic, and dermatologic adverse effects.
