Treatment of Lactational Mastitis — No Penicillin Allergy
Lactational mastitis is an inflammatory process affecting the lactating breast. In patients with no penicillin allergy, first-line therapy follows a specific antibiotic and supportive care pathway distinct from penicillin-allergic alternatives.
Clinical Scenario
Lactational mastitis in a breastfeeding patient confirmed to have no penicillin allergy. This distinction is clinically important: penicillin-allergy status determines which antibiotic agents are appropriate and shapes the full management approach.
Treatment Overview — partial
Management combines oral analgesia as the first-line approach to pain, which may be supplemented with an anti-inflammatory agent. Antibiotic therapy targeting the common causative organism is a core component, with the full antibiotic choice, course length, and dosing schedule specified in the complete protocol. Supportive breast care — including drainage techniques and temperature measures around feeds — is also part of the regimen.

Clinical Goal
Settling of breast inflammation, confirmed at clinical review within 24–48 hours of starting treatment.

- Regular oral paracetamol is first line treatment.
- Nonsteroidal anti-inflammatory drugs can be added.
- As S. aureus is the common causative organism, antibiotic therapy of choice at least 5 days of flucloxacillin or dicloxacillin in a dose of 500 mg four times per day.
- Gentle massage and warm compress prior to feeding (may encourage milk flow).
- Application of cold packs after feeding (may help alleviate pain).
- Regular and complete drainage of breast (use breast pump if needed).
- Women with mastitis should be reviewed within 24–48 hours to ensure that the inflammation is settling.
