Alternative Agents & Management

    • Nitrofurantoin 2 mg/mL suspension can be made from nitrofurantoin bulk powder and SyrSpend SF PH4 vehicle. Mix nitrofurantoin with a small amount of suspending vehicle to form a paste. Dilute the paste with additional SyrSpendSF to a final volume of 300 mL. Store at room temperature or under refrigeration in light-resistant bottles. Suspension is stable for 90 days.[1]
    • Macrodantin (nitrofurantoin macrocrystalline) capsules can be opened and mixed with food or water and flushed down a tube.[2]
    • Macrobid (nitrofurantoin monohydrate/macrocrystalline) capsules should not be opened as this may interfere with the nitrofurantoin release mechanism.[2]
