From the Guidelines
For postpartum wound infections, the recommended antibiotic treatment is amoxicillin-clavulanate or cloxacillin as the first choice, according to the most recent guidelines from the WHO Essential Medicines and Aware recommendations on first- and second-choice antibiotics for empiric treatment of clinical infections 1.
Recommended Antibiotics
- Amoxicillin-clavulanate is a broad-spectrum antibiotic that covers a wide range of potential pathogens, including Group A Streptococcus, Staphylococcus aureus, gram-negative bacilli, and anaerobes.
- Cloxacillin is an anti-staphylococcal penicillin that is effective against Staphylococcus aureus, including methicillin-resistant Staphylococcus aureus (MRSA).
Dosage and Duration
The dosage and duration of antibiotic treatment may vary depending on the severity of the infection and the patient's response to treatment. However, a typical regimen for amoxicillin-clavulanate is 875/125mg twice daily, and for cloxacillin, it is 500mg four times daily.
Considerations
- The choice of antibiotic should be based on the severity of the infection, the patient's allergies, and local resistance patterns.
- The treatment should be continued for at least 48 hours after the patient becomes afebrile and symptoms improve, and then transitioned to oral antibiotics to complete a 7-10 day course.
- Adjustments may be necessary based on culture results, patient allergies, or local resistance patterns, as recommended by the Infectious Diseases Society of America guidelines 1.

Recommended Antibiotics for Postpartum Wound Infections
- The first-line antibiotic therapy for postpartum endometritis is amoxicillin-clavulanic acid 3 to 6 grams per day, depending on the weight, intravenously or orally 2.
- In case of impossibility to use penicillins, the combination of clindamycin 600mg×4/d plus gentamicin 5mg/kg×1/d may be used, but this must be a specialized decision in case of maternal breastfeeding 2.
- The combination of clindamycin and gentamicin is appropriate for the treatment of endometritis 3.
- Regimens with good activity against penicillin-resistant anaerobic bacteria are better than those with poor activity against penicillin-resistant anaerobic bacteria 3.
- A single dose of intravenous co-amoxiclav (1 g of amoxicillin/200 mg of clavulanic acid) after operative vaginal birth is clinically effective for preventing confirmed or presumed maternal infection 4.
Specific Situations
- For postpartum perineal wounds, antibiotics should not be prescribed systematically to contain healthcare costs 5.
- For postcesarean endometritis, monotherapy with a beta-lactam antibiotic such as ticarcillin disodium/clavulanate potassium may be effective 6.
- For operative vaginal birth, a single dose of prophylactic co-amoxiclav is recommended to prevent infection 4.
General Principles
- The treatment of postpartum endometritis should be continued until obtaining 48 hours of apyrexia and the disappearance of pelvic pain 2.
- In case of persistence of fever and/or pelvic pain after 72 hours of antibiotic therapy, pelvic imaging should be performed to rule out complications such as placental retention, septic thrombophlebitis, or deep abscess 2.
