Wrong reason, but I'm glad it's off the market. If it was a better drug, I suspect it would be reformulated the way the albuterol inhalers were (CFC propellant changed to HFA). The manufacturers didn't reformulate, probably because they know the time is up for this as a treatment for asthma.
Look if you have Asthma or COPD and need a drug in an emergency you will have to go to the Emergency Room now. This drug or inhaler is like most ones that you get from the doctor except it has a gas that blows the Chemical out. This drug is no more dangerous than Symbicort or Combivent all of them have side affects..
