How Ciprofloxacin Works

Ciprofloxacin works by inhibiting the growth of bacteria. It does this by interfering with the DNA replication process of the bacteria.

This action helps to stop the spread of the infection and allows the body’s immune system to eliminate the bacteria.

As a fluoroquinolone antibiotic, it targets specific enzymes that bacteria need to multiply and repair themselves.
