Ampicillin is in the family of antibiotics known as penicillins. The drug blocks the formation of the bacterial cell wall and is approved in a number of bacterial infections, other than food poisoning, caused by streptococci, pneumococci, Listeria, Salmonella, Shigella, and E. coli, among others.
Original uses (on-label)
Infections of the respiratory tract and soft tissues caused by susceptible organisms; bacterial meningitis caused by susceptible organisms; septicemia; gonococcal infections; prevention of bacterial endocarditis.
Newly discovered uses (off-label)
Also, you can buy principen to treat cholera, food poisoning.
Potential side effects
May include diarrhoea, nausea, and rashes. Rashes, which should be reported to a doctor, are most common in patients suffering from glandular fever, chronic lymphatic leukaemia, and HIV infection and in patients who are also taking allopurinol.
- Principen should not be taken by anyone with known allergy to penicillins, and it should be used with caution in people with severe kidney disease.
- Methotrexate: concentrations of methotrexate in the blood are increased, which may cause toxic effects.
- Oral contraceptives: their contraceptive effect may be reduced.
- Additional contraceptive precautions should therefore be taken with short courses of ampicillin and for seven days after stopping; if these days run beyond the end of a packet of oral contraceptives, the next packet should be started immediately without a break.
Food decreases ampicillin absorption rate and may decrease ampicillin serum concentration.

Treatment of cholera
Principen can reduce the volume of diarrhea in patients with severe cholera. This drugs can also shorten the excretion time of the microorganism involved with cholera known as Vibrio cholerae.
In general, antibiotic therapy for cholera is considered in addition to fluid therapy. Antibiotics such as Principen reduce diarrhea volume and duration by about 50%, they can shorten hospitalization time.
In a review article published by a researcher in The Netherlands, Principen, among other traditional antibiotics, was mentioned as the mainstay therapy for the management of bacterial Salmonella infections from food.
Also mentioned was that the increasing resistance to these traditional antibiotic drugs necessitates the use of different types of antibiotics for this type of bacterial disease.
Food Poisoning Treatment
Case reports also document the use of ampicillin for Salmonella infections. In one instance, a pregnant woman came down with gastroenteritis one week before delivery.
The newborn infant was subsequently treated with Principen, gentamicin (an antibiotic), and amoxicillin
(an antibiotic); however, five months later, Salmonella was still present. In this case, researchers discussed the potential route of infection and the guidelines for treatment and management of this type of bacterial infection in pregnancy and post-partum.
