I just had an asthma attack and took a few minutes to get to my inhaler. coughing stopped quickly after i used it but now feeling very shaky. why?

Albuterol: Good that your inhaler brought about quick resolution of your symptoms! There are a few things about an asthma attack that can make you feel shaky afterwards...but most likely is that this is an effect of the medication itself, which is a "cousin" of caffeine, and shares some of the effects. But if shakes do not resolve within hours, or if you have other symptoms (chest pain, etc.), go see a doc.
