What is Macrobid Macrocrystal (Nitrofurantoin) prescribed for?

Bladder infections have a way of gaining your utmost attention, by making you journey to the washroom countless times, and it is the most common type of urinary tract infection.  When you get a bladder infection it leads to cystitis, which is when your bladder swells and becomes irritated. In turn this is what causes the symptoms.

This medication is an antibiotic, and it works by stopping the growth of the bacteria in the body that creates these symptoms.

Remember that this medication only treats bacterial infections; it will not work for any viral infections, such as the common cold and the flu.

This medication is to be taken by mouth. Usually twice a day, every 12 hours. Swallow the medication whole.

Do not take magnesium trisilicate-containing antacids while taking this medication.  These antacids can bind with Nitrofurantoin, which prevents its full absorption into your system. Be sure to take this medication at evenly spaced times, and remember that the dosage is based on your medical condition and your response to the treatment.

Continue to take this medication until full prescribed amount is complete, even if your symptoms disappear after a few days. Discontinuing in taking the medication too early may allow the bacteria to continue to grow and result in a return of the infection.
