I assume you're referring to adhd meds. You'd have a better chance of a reply if you ask in an asthma forum, and if you specify exactly which meds you're talking about.
I appreciate that but I'm just making conversation/curious. I have a good handle on my asthma, I'm wondering if others have found that to be the case also.
Was intrigued by a poster saying he treats his COPD with basically ibuprofen+pseudoephedrine which I find mind-boggling but it seems like it would be related to stimulant-mediated vasoconstriction.
