Nebulized therapy is often called a “breathing treatment”, applied with a small machine called a nebulizer. A variety of medications — both for immediate relief and maintenance of symptoms — are available for use with a nebulizer. Nebulizers come in home (tabletop) and portable models. Home nebulizers are larger and must be plugged into an electrical outlet. Portable nebulizers run on batteries — either disposable or rechargeable — or can be plugged into a car’s cigarette lighter. Smaller, portable units are slightly larger than a deck of cards, so they can be carried in a purse, briefcase, or backpack to be used whenever and wherever you need them.
