How Ampicillin Works

Ampicillin works by interfering with the formation of the bacterial cell wall. Without a proper cell wall bacteria become weak and break apart which helps the body clear the infection.

The medication controls bacterial growth and helps resolve symptoms. It may cure susceptible infections when used correctly but incomplete courses can allow bacteria to survive and contribute to antibiotic resistance.
