Nebulizers are machines that you breathe into. After you put medication in the mouthpiece, the nebulizer changes it from liquid to mist that you inhale. The medication helps relieve symptoms of asthma and other lung conditions like COPD. A prescription is required to get a nebulizer. They can cost $50 and higher. Instructions will come with your nebulizer -- it's important to carefully follow these directions so that you get an effective breathing treatment. Follow the links below to find WebMD's comprehensive coverage about how nebulizers are used, who needs them, how they work, and more.
