I was just wondering if anyone else noticed this? I'm in the U.S. so I take xopenex (which is very similar to albuterol). Sometimes when I take 2 puffs of my rescue inhaler, it helps quickly (usually when I'm not sick). But when I take it when I'm sick, sometimes the wheezing gets worse for a while before it gets better. Sometimes when I take it throughout the day (every 5 hours) the wheezing is much worse.
