This is a question of Tom Hale. A breastfeeding mother with Asthma has been prescribed an inhaler that has a primary ingredient of Pirbuterol Acetate. I have looked everywhere and can not find it. I do not have Tom's latest edition so it may be in there. Any ideas. This is a committed breastfeeding mother who probably would opt not to take the drug if it is not compatible with breastfeeding. Thanks Donna
