Sue, I have wrongly resisted using levalbuteral inhalers for a dumb reason. My dad had asthma and our life revolved around rushing to the drugstore to get him another inhaler as he’s gasping, neglecting to ever have a stand by. I was tested for asthma many times, told I didn’t have it but to try this or that inhaler to see if it helped my lung power. I didn’t want to live like my dad, dependent on an inhaler. Your description makes me (1) knock my head against the wall for refusing and (2) deciding to ask my pulmonologist for a prescription. Thanks.
