  • Offering the baby the inflamed breast first to promote complete emptying of infected breast
  • Using a breast pump to express milk
  • Applying warm compresses to breasts prior to feeding to stimulate milk ejection reflex

Pain Relief

To reduce pain and swelling in the breast:
  • Apply ice compresses to the affected area of your breast after breastfeeding.
  • Consider using over-the-counter pain relievers as recommended by your doctor.
  • Be sure to ask your doctor what pain relievers are safe for you and your baby. Taking aspirin is not advised during pregnancy or breastfeeding.
  • Drink lots of fluids.
  • Get plenty of rest.


Antibiotics may be used to treat the infection. They may help cure the infection or reduce the risk of more serious but rare complications such as blood infection. If you are breastfeeding, talk to your doctor about which antibiotics are best for you to take so you can continue to breastfeed.
If mastitis does not respond to antibiotics, a localized collection of pus called an abscess might be present. This is usually treated with other antibiotics and a drainage procedure or surgery.
