NAC and asthma

[Hopeny]

In my never ending googling I have come across some information that NAC can cause bronchiospasm so should be used with caution in pts with asthma. DD has mild asthma and is taking NAC. I have noticed her having an asthma cough after she drinks her supplement smoothie, but I attributed it to the drink being cold. Now I read this abbout NAC and it has me wondering. DD's asthma actually seems generally better, she is also on Enhansa and Quercetin so am thinking those two are probably the reason for improvement. Just wondering if anyone has had experience with NAC and asthama? DD is taking 300 MG/day of pharma NAC. We have consult in 2 weeks and this is on my list but curious what others say. Interestingly as an aside I read that NAC IV is the antidote for Tylenol OD.
