Macrobid (generic name: nitrofurantoin; brand names include: Niftran / Macrodantin / Furadantin) is used for treating and preventing urinary tract infections caused by certain bacteria.
Macrobid is indicated for:
the treatment of acute uncomplicated urinary tract infections (acute cystitis);
for short- and long-term prophylaxis of urinary tract infections.
It works by interfering with various chemical processes in the bacteria, which results in the death of the bacteria.
Follow the directions for using this medicine provided by your doctor. Take Macrobid exactly as directed.
Take medicine by mouth with food, preferably breakfast and dinner, or milk to enhance tolerance and improve absorption of Macrobid.
Do not take an antacid that has magnesium trisilicate in it while you take Macrobid. Check with your pharmacist if you are unsure which antacids have magnesium trisilicate in them.
To clear up your infection completely, take Macrobid for the full course of treatment. Keep taking it even if you feel better in a few days.
If you miss a dose of Macrobid, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Macrobid does not interfere with the ability to drive or use machines. It is not expected to be harmful to an unborn baby. The tendency of Macrobid to impart a brown colour to the urine is of no clinical significance.
