A nebulizer changes medication from a liquid to a mist so you can inhale it into your lungs.

Nebulizers come in home (tabletop) and portable models. Home nebulizers are larger, and you have to plug them into an electrical outlet. Portable nebulizers run on batteries, or you can plug them into a car outlet. Some are only a bit bigger than a deck of cards, so you can carry them in a bag or briefcase.

You may need a doctor’s prescription for a nebulizer, or you can get one at your pediatrician’s office. Many people also get breathing treatments at their doctor's office.

Home nebulizers cost about $50 and up, plus the cost of accessories. Portable nebulizers usually cost a little more.

Health insurance policies usually cover nebulizers under their durable medical equipment portion.

But most insurance companies want you to work with a certain supplier. Check with your insurance provider before buying or renting a nebulizer. Your health care team should be able to help you..
