I'm very mildly asthmatic (really, exercise-induced bronchospam, I think) and breastfeeding. I'm having problems getting reliable information about my inhaler, which is Salbutamol Sulphate. My SIL (a doctor) looked it up in the book and they were quite vague about it.
I know that inhalers are normally non-optional, but I can avoid using it ... if I avoid cardio exercise, particularly outside, particularly in this weather. This isn't a very appealing prospect. I'd rather go without running than give up breastfeeding, by a very large margin, but do I really have to give up?
