Taking antibiotics for mastitis while breastfeeding

Mastitis can involve breast inflammation alone or inflammation with bacterial infection. Breast tenderness, heat, redness and flu-like symptoms can occur, so examination and the pattern of illness matter when deciding on antibiotics. Treatment aims to control infection while maintaining comfortable feeding and preventing worsening swelling or a collection of pus.

Take the prescribed antibiotic exactly as directed and complete the course unless the prescriber changes the plan. Tell them about medication allergies and any reaction your baby has previously had to medicines. Breastfeeding can generally continue, and stopping suddenly may increase fullness. Feed responsively, express only as needed for comfort or your baby's intake, use cool packs after feeds and avoid hard massage over inflamed tissue.

Get prompt advice if fever or breast redness is worsening, a lump is enlarging, pus appears, pain becomes severe or you remain generally unwell after starting treatment. A firm, tender collection may be an abscess and can need imaging and drainage. Seek urgent help for breathing difficulty, facial or throat swelling, widespread blistering, fainting or confusion after taking medicine.

Confirm how to take each dose, what side effects to watch for in you or your baby, and when symptoms should be reassessed. Ask whether a milk sample, breast scan or drainage is appropriate if treatment has not helped or mastitis keeps returning. Feeding support can also identify nipple damage, ineffective attachment or pumping settings that maintain irritation.
