Xopenex vs Albuterol??? Please Advise!!!

Hi Ladies, My 5 year old DS just started his first bad cough and of course it turns out he has bronchitis !! His ped prescribed him albuterol or xopenex ... I read the literature and both seem to have the same side effects so would like some feedback as to which would be better based on personal experiences of course!! I have to begin his nebulizer treatment today and am so on egde and hate to see him cough so bad...any other natural remedies than can ease his discomfort and any other advise will be greatly appreciated ! Thanks! ...
