Sorry Pedal Wrench but I have to strongly disagree with you on the use of Primatene Mist. You can google dangers of Primatene Mist and deaths that may be attributed to using over the counter asthma medications. If you have asthma you need to see a pulmonary specialist and get the right medication and correct dosage. In most cases preventing an asthma attack is much better than trying to stop one already in progress. Asthma can be life threatening!
