Proper Use

Drug information provided by: Merative, Micromedex®

Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered.

Nitrofurantoin is best taken with food or milk. This may lessen stomach upset and help your body to absorb the medicine.

To help clear up your infection completely, keep taking this medicine for the full time of treatment, even if you begin to feel better after a few days. Do not miss any doses.

Shake the oral liquid forcefully before each dose to make sure the medicine is evenly mixed. Use a specially marked measuring spoon or other device to measure each dose accurately. The average household teaspoon may not hold the right amount of liquid.

Swallow the capsule whole. Do not open, crush, or chew the capsule before swallowing it.

Do not take antacids containing magnesium trisilicate (e.g., Genaton®) while you are using nitrofurantoin. It may prevent the medicine from working properly.
