Ampicillin is an antibiotic medication used to treat bacterial infections in the genitourinary, respiratory, and the gastrointestinal tract as well as gonorrhea and meningitis.

Ampicillin is a semisynthetic penicillin derivative that combats bacteria throughout your body to fight various infections. The bactericidal has been found to be effective against organisms susceptible to penicillin as well as some gram-negative bacteria. This allows the medication to treat conditions such as bladder infections, pneumonia, gonorrhea, and meningitis.

This antibiotic is easily absorbed by your gastrointestinal tract and can kill harmful bacteria that ordinary penicillin might miss.

This antibiotic is absorbed through your gastrointestinal tract into your tissues and bodily fluids to reach harmful bacteria throughout your body except for cerebrospinal fluid and your brain which only occurs when there is meningeal inflammation. As it moves through your body, Ampicillin attacks harmful bacteria and inhibits its ability to grow or spread.
