Health conditions


Mastitis is a common but preventable breastfeeding problem.

What is mastitis?

Mastitis occurs when there is a blockage of milk in the milk duct. Some milk may leak out of the duct into the surrounding tissues causing inflammation and infection.

Terms explained

Milk ducts are small tubes inside the breast that carry milk through to the nipples

Signs and symptoms

  • The breast has a red, painful area.
  • An aching flu-like feeling such as a fever, feeling shivery and generally unwell.

How do I know I have mastitis?

Seek medical help if fever lasts more than 6 hours.

Treatment of mastitis

  1. Drain the breast frequently. Attach your baby to the affected side first.
  2. You may need antibiotics for 10 to 14 days.
  3. Keep the breast drained by expressing the affected breast after each feed.
  4. Cool gel packs from refrigerator (not freezer) or cool cloths can relieve discomfort and pain.
  5. Anti-inflammatory medication such as ibuprofen will reduce the inflammation and pain.
  6. Paracetamol may be taken to ease discomfort.
  7. It is important to get extra rest. You may need household help to achieve this.
  8. If it is too painful to feed, express your milk using a hospital grade electric pump if possible.
  9. Seek advice from a lactation consultant to determine a cause and prevent a reoccurrence.
