Can You Continue Breastfeeding While Experiencing Mastitis and Fever?

Breastfeeding is generally safe and even recommended during mastitis—a common inflammatory condition of the breast tissue, often occurring in lactating individuals. Mastitis typically presents with localized breast pain, swelling, warmth, erythema, and systemic symptoms such as fever, chills, and malaise. While it may be tempting to stop nursing when feeling unwell, continuing breastfeeding (or regular milk expression) is a cornerstone of management.

There is no evidence that breast milk becomes harmful or contaminated during mastitis. The infection—most commonly caused by *Staphylococcus aureus* or other skin flora entering through nipple fissures or ductal obstruction—is localized to the breast parenchyma and does not alter milk safety. In fact, frequent and effective milk removal helps resolve ductal stasis, reduces inflammation, and supports faster clinical recovery.

Clinical guidelines from the American Academy of Pediatrics (AAP), the World Health Organization (WHO), and the Academy of Breastfeeding Medicine (ABM) uniformly endorse continued breastfeeding during uncomplicated mastitis. If antibiotics are prescribed—such as dicloxacillin, cephalexin, or clindamycin—they are selected specifically for safety during lactation and do not contraindicate nursing.

Mothers should be encouraged to nurse frequently on the affected side, ensure optimal infant latch and positioning, apply warm compresses before feeding, and rest adequately. If severe pain or abscess formation develops—characterized by fluctuant, non-tender swelling—ultrasound evaluation and possible ultrasound-guided aspiration or incision and drainage may be required. In such cases, breastfeeding can usually continue from both breasts unless contraindicated by surgical intervention.

Stopping breastfeeding abruptly increases the risk of worsening inflammation, recurrent mastitis, or progression to breast abscess. Therefore, unless medically advised otherwise—for example, in rare cases involving specific antimicrobial regimens or complex surgical management—lactation should be maintained throughout treatment.
