What Are Nebulizers and Inhalers?
Nebulizers and inhalers turn liquid medicine into a mist so that kids can breathe it in. Some inhalers release the medicine in a fine powder form that also can be breathed in.
These tools are effective when used properly. But each have their pros and cons — so talk to your doctor about which one is best for your child.

How Does a Nebulizer Work?
A nebulizer is an electric or battery-powered machine. It usually has four parts:
- the motor
- the mouthpiece or facemask
- the cup
Medicine is put into the cup, which is attached to the motor via tubing. The mouthpiece or facemask is then attached to the cup. When the machine is turned on, it sends a mist into the mask. The child can breathe in this mist.
Kids don’t have to “do” anything to receive the medicine except stay still and breathe in. It usually takes about 5 or 10 minutes to breathe in all the medicine. A child who doesn’t stay still and cooperate, or who cries, may not get all the medicine needed. During treatment, it’s important to help your child be as still and calm as possible.
How Does an Inhaler Work?
Metered dose inhalers (MDI)
MDIs push out a pre-measured spray of asthma medicine. They look like mini aerosol cans. When a person squeezes the inhaler, a measured “puff” of medicine is released.
MDIs require coordination when used on their own. A child must be able to activate the device and breathe in at the same time. If not, the medicine may end up in the mouth instead of in the lungs. That’s why for younger kids many doctors recommend attaching the metered dose inhaler to a spacer.
A spacer is a kind of holding chamber for asthma medicine. It attaches to the inhaler on one end and to a mouthpiece or mask on the other end. When someone pushes down on the inhaler, the medicine stays in the spacer until he or she is ready to breathe it in. So, it’s possible for very young kids and even babies to take their medicines using a metered dose inhaler with a spacer because they don’t have to “do” anything other than sit and breathe.
With a spacer, it usually takes less than 30 seconds to get medicine into the lungs.
Some MDIs have counters that indicate how many doses remain. If there’s no counter, the number of doses already used should be tracked so that the inhaler can be replaced on time.
Dry Powder Inhalers
Dry powder inhalers deliver medicine as a powder. The powder is also breathed in, but it doesn’t spray out. Kids need to do more of the work by inhaling the powdered medicine quickly and strongly. Most kids can do this when they’re around 5 or 6 years old.
Doctors tend to prescribe MDIs more commonly than dry powder inhalers.
What Else Should I Know?
Using nebulizers or inhalers can be tricky. So ask your doctor to show you how the device works before you first use it. Doctors might ask an older kid or teen to demonstrate using an inhaler and offer advice, if needed.
If you have any questions or if you’re concerned that your child isn’t getting the right dose of medicine, talk to your doctor.
