Description

What are Nitrofurantoin Capsules?

Nitrofurantoin capsules contain the active ingredient nitrofurantoin, an antibiotic specifically designed to treat bacterial infections in the urinary tract, most commonly acute cystitis (bladder infection). Unlike broad-spectrum antibiotics, nitrofurantoin is a narrow-spectrum antibiotic that works mainly within the urinary system.

How Nitrofurantoin Works

Once taken, nitrofurantoin is processed by the body and concentrated in the urine, reaching the bladder in high levels where it directly attacks and kills the bacteria responsible for the infection.

  • Pain or discomfort in the lower abdomen
