Transcript for Health Warning: Millions May Be Misusing Asthma Inhalers
We have a health warning now for the millions of Americans that suffer from severe allergies or asthma. One in six people are using epipens correctly, and fewer with asthma using the inhalers the wrong way. This is an eye opener. How are they getting it wrong? Either not trained properly, or years ago and forget how to do it. It can be life threatening. What's the proper way to use the epipen and the most common errors? This is for people who have life-threatening food allergies, bee stings. Grip it in your palm, and swing it down into your thigh. You'll hear the click. But you have to leave it in place for ten seconds so the medicine comes through. People put it there, hurts, comes out. So ten seconds to get the medicine in. There are tips on how to properly use an asthma inhaler as well. Millions of people use this with a spacer or without. The key thing here is, before you breathe in, you have to breathe out. Empty your lungs fully of the air. So when you release the medicine, it goes deeply into your lungs. Completely empty. As much as you can. And open your airways. Next time you go to the doctor, demonstrate how you're using them, and they can correct your behavior. I'll be answering your questions all morning on Twitter. Thanks, rich.
