Ampicillin 250 mg is a penicillin-like antibiotic intended for the treatment of different infections (respiratory infections, genital and urinary tract infections, gastrointestinal infections, meningitis, and several other types) that works by slowing down the growth of bacteria. You must not start taking this medicine if you are allergic to cephalosporin or penicillin antibiotics. The symptoms of a severe allergic reaction to ampicillin may include a sore throat, a skin reaction, fever, diarrhea, wheezing, and shortness of breath. If you have these symptoms, emergency medical assistance is required.
Ampicillin 250 is a broad-spectrum antibiotic from the aminopenicillin group. Its mechanism of action is anti-bacterial and consists of inhibition of the construction of bacterial cell walls sensitive to Ampicillin. It is not destroyed by the acidic content of the stomach and is easily absorbed. Ampicillin is active toward gram positive microorganisms and also some gram negative ones (salmonella, schigella, proteus, E. coli, Klebsiella pneumoniae, Haemophilus influenzae, formerly called Pfeiffer’s bacillus) and is used for treatment of diseases provoked by mixed bacteria. Microorganisms producing penicillase are resistant to ampicillin. This medication is used to treat pneumonia and other infectious diseases of the respiratory, urogenital, and gastrointestinal systems.

If you have taken Ampicillin for a long time, it may appear ineffective in your organism due to a so-called “superinfection.” Inform your doctor if your symptoms do not improve or get worse.
