For skin and soft tissue infections, ampicillin may be used as part of combination therapy for certain infections 1
For streptococcal pharyngitis, ampicillin can be considered when appropriate, with dosing similar to amoxicillin (50 mg/kg once daily, maximum 1,000 mg) for 10 days 2, 3
For uncomplicated urinary tract infections, treatment duration of 3-7 days is typically sufficient, according to the American Academy of Family Physicians 4
When treating chronic carriers of Group A Streptococcus, ampicillin alone may be less effective than other regimens, as recommended by the American Academy of Family Physicians 2, 3
