Methods to Clear Blocked Breast Ducts

- 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
- 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.
