Doctors often prescribe antibiotics such as vancomycin, clindamycin, erythromycin, tetracycline or cephalosporins to treat bowel infections, according to Medscape. The choice of antibiotic depends on the type of infection and the severity of illness.
Supportive care, such as drinking fluids and eating small snacks, is sufficient for most bowel infections, notes Healthline. Antibiotic treatment is only needed if the infection becomes more severe, or if a patient is at high risk. Infants and immunocompromised patients sometimes require antibiotics for moderate infections, states Medscape.
Doctors must monitor antibiotic treatment carefully, since some infections may respond differently to different drugs. One particular infection, C difficile, can actually result from antibiotic use, according to Medscape, Discontinuation of antibiotic treatment may be necessary in such cases.
