- Post-menopausal usually E. coli, Group D strep, Staph, anaerobes
- Usually sub-areolar area due to chronic duct inflammation
- 40% recurrence rates even after I&D
Clinical Features
- Fever/chills
- Flulike symptoms
- Breast exam shows erythematous region on breast w/ well-localized area of tenderness

- For mild symptoms <24 hours, supportive care may be sufficient[1]
- Effective milk removal (frequent breast feeding - use pumping to augment milk removal)
- Analgesia (NSAIDs)
Treatment directed at S. aureus and Strep and E. coli
- Uncomplicated mastitis → 10 days of antibiotics (regardless of MRSA suspicion)[2]
- Dicloxacillin 500mg PO q6hrs, considered first line if breastfeeding given safety for infant OR
- Cephalexin 500mg PO q6hrs OR
- Clindamycin 450mg PO q8hrs (also provides MRSA coverage) OR
- Amoxicillin/Clavulanate 875mg PO q12hrs OR
