Why is ampicillin prescribed to patients?
Ampicillin is used for treating infections of the middle ear, sinuses, stomach and intestines, bladder, and kidney caused by susceptible bacteria. It also is used for treating uncomplicated gonorrhea, meningitis, endocarditis and other serious infections. Because of the increased use of antibiotics, many bacterial strains have become resistant to penicillins; bacteria causing serious infections should be tested for resistance against penicillins and other antibiotics.
What are the side effects of ampicillin?
Common side effects of ampicillin include:
- loss of appetite,
- abdominal pain,
- confusion and
Patients with a history of allergic reactions to other penicillins should not receive ampicillin. Persons who are allergic to the cephalosporin class of antibiotics, which are related to the penicillins may or may not be allergic to penicillins [for example, cefaclor (Ceclor), cephalexin (Keflex), and cefprozil (Cefzil)]. Serious but rare reactions include seizures, severe allergic reactions (anaphylaxis), and low platelet or red blood cell count.
Ampicillin can alter the normal bacteria in the colon and encourage overgrowth of some bacteria such as Clostridium difficile which causes inflammation of the colon (pseudomembranous colitis). Patients who develop signs of pseudomembranous colitis after starting ampicillin (diarrhea, fever, abdominal pain, and possibly shock) should contact their physician immediately.
