How does Macrodantin work? Macrodantin…
How does Macrodantin work?
- Macrodantin capsules contain the active ingredient nitrofurantoin, which is a type of medicine called an antibiotic. Antibiotics are used to treat infections caused by bacteria. Nitrofurantoin is also available without a brand name, ie as the generic medicine.
- Nitrofurantoin is filtered out of the blood and into the urine by the kidneys. High levels of the medicine pass into the urine, which means that nitrofurantoin can be used to treat bacterial infections in the urinary tract.
- Nitrofurantoin works by killing the bacteria that are causing an infection. It does this by entering the bacterial cells and damaging the genetic material (DNA) of the bacteria. This means that the bacteria cannot reproduce and repair themselves. This kills the bacteria and controls the infection.
- Your doctor may ask you for a urine sample to make sure the bacteria causing the infection are susceptible to nitrofurantoin.
