Azmacort is an inhaled steroid. The oral steroids include prednisone and prednisolone, which are compatible with breastfeeding. The reason for the inhaled form is that it has good local action with virtually no absorption into the body. If oral steroids are compatible with breastfeeding, then an inhaled form with negligible absorption into mother's bloodstream must be even safer. Hope this helps. Alicia. [log in to unmask]
