What factors mean that parents should temporarily suspend breastfeeding?

    Last Updated: May 16, 2025

    Parents should temporarily suspend breastfeeding and not feed expressed milk if they have untreated brucellosis, have an active herpes simplex virus infection with sores on the breast, are undergoing diagnostic imaging with radiopharmaceuticals, or are taking harmful medications. To maintain milk supply, they can continue lactation but should discard the expressed milk until cleared by a healthcare provider.

    The following should temporarily suspend breastfeeding — and should not feed their infants expressed milk — until cleared by a healthcare provider:

    • Lactating parents with untreated brucellosis
    • Lactating parents with an active herpes simplex virus (HSV) infection with sores on the breast
    • Lactating parents undergoing diagnostic imaging with radiopharmaceuticals
    • Lactating parents taking medications that could be harmful to the breastfeeding infant (see above).[1]

    To maintain milk supply, parents who intend to continue breastfeeding once they are cleared by a healthcare provider should continue lactation but should not feed the expressed milk to the baby (i.e., “pump and dump”).
