thanks for coming to HCM
Asthma is graded into controlled , partially controlled and uncontrolled based on the frequency of thre symptoms..
As per your symptomatology it seems to be uncontrolled or partially controlled so it needs to step up your therapy...
you have to change your inhaler....you may opt for formoterol
combination which will be your controller as well as reliever medication since its onset of action is within 3-4 minutes...
Asthma except for your acute severe asthma
is not a medical emergency...
Your symptoms of anxiety
and palpitaion can be due to excessive intake of albuterol
...so needs changing of inhaled medication..
meet your doctor and best wishes
