I used Primatene Mist for years. One night it had my heart racing so fast and wasn't helping my asthma attack and I ended up in the ER for the first time with my asthma. I thought my heart was going to burst through my chest. I was given Combivent in the ER (albuterol and atrovent combined) and have continued using albuterol since. I don't have insurance and go throught my health dept. I get it for $6.00. The last time I saw Primatene, it was about $17.
