Although no research has been conducted on Intal and breastfeeding, researchers believe it is unlikely that the drug would be passed through breast milk in high enough levels to cause problems in a nursing infant. This is because blood levels of inhaled cromolyn (the active ingredient in Intal) are usually low.

Intal and Breastfeeding: An Overview

Intal® (cromolyn inhalation) is a prescription medication used to treat asthma. It is not known if inhaled cromolyn passes through breast milk. Because of the potentially serious side effects that could occur in the nursing infant, the manufacturer recommends considering the possible risks and benefits before prescribing Intal for women who are breastfeeding. Therefore, if you are breastfeeding or thinking of breastfeeding, make sure to let your healthcare provider know.
