Nebulizer therapy at home delivers medication directly to the lungs, where it is needed and can be most effective. As a result, this kind of therapy works more quickly and gets better results with smaller doses than pills or injections. Although the lungs can only absorb 10–15% of the medication they receive, the American Association for Respiratory Care says that using nebulizers correctly is particularly important. There are many types of medications that can be used with nebulizers. Multiple types of medications can be delivered simultaneously with a nebulizer. Due to the fact that nebulizers require smaller doses of medication to be effective, home nebulizer therapy may lead to fewer undesirable side effects than other forms of therapy. The average home nebulizer therapy session lasts 15 to 25 minutes.
