Treatment of Postpartum Pyelonephritis
Ceftriaxone alone or ampicillin plus gentamicin

Sensitivities with culture should be checked. Treatment is adjusted accordingly and continued for a total of 7 to 14 days; oral antibiotics are used after the initial IV antibiotics.
Women should be encouraged to consume large amounts of liquids.
