asthma, acute
"I have been on albuterol inhalers since the 80s.  I went online to watch how to properly use this respliclick inhaler and quickly learned that medicine is actuated each time you open the cap and also not to let my lips block the air vent as it is right at the back of the mouth piece.  Feeling equipped with good info I felt I was ready to go.  Then came the moment I needed it...  I opened the cap emptied my lungs the best I could (I was having an asthma attack so...could only do so much).  Then I breathed in all I could...my lungs went into a vacuum (negative pressure) and they stayed that way until I released my lips from the device.  Nothing left the inhaler and entered my lungs, not medicine, not air, nothing.  I tried three times and the pain was so bad I don't I think I dare try again.  After 3 hours with no relief I used my expired ProAir HFA and got instant relief.  I am calling the FDA compliant line now."
