Yes, you will certainly be able to breastfeed if you wish to. Asthma medicine, especially that administered in inhaled form, is not a contraindication to nursing your infant. Breast-feeding has many advantages for both mother and child and may even have beneficial effects in delaying or perhaps avoiding altogether the development of asthma in young children. An Australian study involving over 2000 children found that infants who were exclusively breast-fed, that is, who received only mother’s milk for at least the first 4 months of life, had a significantly reduced risk of developing asthma by the age of 6.
Breastfeeding also appears to delay the development of allergy in children. Studies indicate that breast-fed children known to be at increased risk for the development of allergy (because of a family history) develop allergies at an older age as compared to children with similar risk factors who are not exclusively breast-fed. Of course, once your baby is born, you should seek guidance from the pediatrician if you are taking any over-the-counter or prescription medicines in addition to your asthma medicine while you are breastfeeding.
