How well do you know your asthma inhaler? What does it do for you? What drugs are in it? Do you puff and breathe, or breathe and puff?
Inhalers are the most effective way to get lifesaving medications to people with asthma and other lung diseases. Whether you have asthma or care for someone who does, here’s what you need to know about inhalers, including how to use one correctly.
There are usually reasons or risk factors that predispose you to asthma and respiratory problems. Asthma can happen to anyone without any risk factors, but it is less likely if there are no risk factors present.
Let's look at some asthma risk factors and see how they increase the chance that a person will have the asthma symptoms of cough, wheezing, and shortness of breath associated with the disease. After determining your personal risk factors for asthma, decide on the ones you can control and...

Read the instructions carefully if you get a different brand, because they vary widely and the new one may not work like your old one.
Nebulizers deliver medication through a mouthpiece or mask. They’re easier to use because you can breathe normally. That makes them good for children or people with severe asthma who may not be able to use an MDI or DPI properly.

Anti-inflammatory asthma inhalers prevent asthma attacks and reduce swelling and mucus in your airways. They include:
