Nitrofurantoin Macrocrystal Oral Uses
This medication is used to treat or prevent certain urinary tract infections.
This medication is an antibiotic that works by stopping the growth of bacteria. It will not work for viral infections (e.g., common cold, flu). Unnecessary use or overuse of any antibiotic can lead to its decreased effectiveness.
Nitrofurantoin should not be used in children less than one month of age due to the risk of a certain blood problem (hemolytic anemia).
How To Use Nitrofurantoin Macrocrystal Oral
Take this medication by mouth, with food or milk, as directed by your doctor. This medication is usually taken four times daily to treat an infection or once daily at bedtime to prevent infections. Swallow the medication whole. Avoid using magnesium trisilicate-containing antacids while taking this medication. Magnesium trisilicate-containing antacids bind with nitrofurantoin, preventing its full absorption.
Dosage and duration is based on your medical condition and response to therapy. For children, the dosage is also based on body weight.
Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, take this medication at evenly spaced intervals.
When taking this medication to prevent infection, take it exactly as directed by your doctor. Do not skip doses or stop taking it without your doctor's approval. Inform your doctor if you notice signs of a new urinary tract infection (e.g., pain while you are urinating).
If you are taking this medication to treat an infection, continue to take this medication until the full-prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow, which may result in a relapse of the infection. Inform your doctor if your condition persists or worsens.
