Patient Education

Ampicillin Injection


Ampicillin injection is used to treat certain infections that are caused by bacteria such as meningitis (infection of the membranes that surround the brain and spinal cord) and lung, blood, heart, urinary tract, and gastrointestinal tract infections. Ampicillin injection is in a class of medications called penicillins. It works by killing bacteria. Antibiotics such as ampicillin injection will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
