A nebulizer for kids is a small machine that turns liquid medicine into a fine mist your child breathes in through a mask or mouthpiece, so the medicine goes straight to the lungs. Pediatricians most often prescribe one for wheezing from asthma, viral wheezing, or bronchiolitis in babies who cannot yet use an inhaler with a spacer. The most common nebulizer medicines for kids are albuterol for quick relief and an inhaled steroid such as budesonide for daily control. Here is how each type of nebulizer works, which medicines go in them, how to use one with a baby or toddler, and when a nebulizer is not the right tool.
Key takeaways
- Nebulizers deliver medicine as a mist, which makes them easy for babies and toddlers who cannot use an inhaler and spacer yet.
- Common nebulizer medicines for kids are albuterol (quick relief) and budesonide (daily controller). Use only what your child’s doctor prescribed.
- An inhaler with a spacer works as well as a nebulizer for most children, and it is faster and portable.
- Wheezing that does not improve 20 minutes after a treatment, or needing rescue medicine more often than every 4 hours, needs care now.
What is a nebulizer and how does it work?
A nebulizer has three parts: a compressor or electronic base, a small cup that holds the liquid medicine, and a mask or mouthpiece. Air or vibration breaks the liquid into tiny droplets your child breathes in during normal, relaxed breathing. No special breathing technique is needed, which is why nebulizers work well for babies.
Each treatment usually takes about 5 to 20 minutes, depending on the machine and the dose. [Source: MedlinePlus, How to Use a Nebulizer]
What types of nebulizers are there for infants and kids?
| Type | How it works | Good for | Trade-offs |
|---|---|---|---|
| Jet (compressor) nebulizer | A compressor pushes air through the medicine to make mist | Home use, all ages, budget friendly | Noisy, needs an outlet, bulkier |
| Mesh nebulizer | A vibrating mesh pushes medicine through tiny holes | Travel, quiet treatments, sleeping toddlers | Costs more; mesh needs careful cleaning |
| Ultrasonic nebulizer | Sound waves turn liquid into mist | Quiet, fast | Not compatible with every medicine; check with us first |
For babies, the mask matters more than the machine. Use the pediatric or infant mask that came with the kit, and make sure it seals around the nose and mouth.
What nebulizer medicine is used for kids?
Only use the medicine and dose your child’s doctor prescribed. The most common options:
- Albuterol (or levalbuterol). A quick-relief bronchodilator that opens tight airways within minutes. It is used for wheezing, coughing fits, and asthma flares. Shakiness and a fast heartbeat for a short time afterward are common.
- Budesonide. An inhaled steroid used once or twice a day to calm airway swelling over time in children with persistent asthma. It works as prevention, not for sudden symptoms.
- Ipratropium. Sometimes added to albuterol during a flare, usually in the office or hospital.
- Saline. Normal or hypertonic saline is sometimes prescribed to loosen mucus. It can make some children cough or wheeze more, so use it only if your doctor recommends it.
The AAP’s home guidance for an asthma attack is to start rescue medicine at the first sign of wheezing, shortness of breath, or hard coughing, repeat every 4 hours while symptoms continue, and call the doctor if it is needed more often than every 4 hours.

When do kids need a nebulizer?
Pediatricians commonly use or prescribe nebulizer treatments for:
- Asthma and asthma flares, for quick relief and, in some children, daily controller medicine. Read understanding childhood asthma.
- Viral wheezing in toddlers, often set off by colds.
- Walking pneumonia or other lung infections that cause wheezing; see walking pneumonia in kids.
- Croup, where certain treatments may be given in the office or ER; see croup in toddlers.
Bronchiolitis from RSV is different. For most babies with bronchiolitis, albuterol does not help, and treatment is supportive care: suction, fluids, and watching breathing. Our guide to RSV in babies explains when to worry.
A nebulizer is also not a treatment for a plain stuffy nose. For congestion, saline drops and suction before feeds and sleep work better.
Is a nebulizer or inhaler better for my child?
For most children, an inhaler with a spacer works just as well as a nebulizer. The AAP recommends using a spacer with every inhaler because it delivers about twice as much medicine to the lungs as the inhaler alone. [Source: AAP HealthyChildren.org, Symptom Checker: Asthma Attack]
| Age | Usual choice |
|---|---|
| Under 1 | Nebulizer with infant mask, or inhaler with spacer and infant mask |
| 1 to 4 years | Either, with a well-fitting mask |
| 5 and up | Inhaler with spacer and mouthpiece; nebulizer if preferred |
Many families keep both: a nebulizer at home and an inhaler with a spacer for daycare, school, and travel. Our post on when to use a nebulizer for a toddler covers the symptoms that usually call for one.
How do I use a nebulizer with a baby or toddler?
- Wash your hands and set the machine on a flat surface.
- Measure the exact prescribed dose into the cup.
- Hold your child upright on your lap.
- Fit the mask snugly over the nose and mouth. Avoid “blow by” (holding the tube near the face); most of the medicine is lost.
- Distract with a show, book, or song. Calm breathing gets more medicine into the lungs than crying.
- Run until the cup sputters and stops misting, then clean the parts.
Cleaning: rinse the cup and mask after every use and air-dry; wash with mild soap daily; soak in 1 part white vinegar to 2 parts warm water once or twice a week; never wash the tubing. [Source: MedlinePlus, How to Use a Nebulizer]
When should I call or go to the ER?
Based on the AAP asthma attack guide:
- Call 911 for severe trouble breathing, a child who can barely speak or cry, bluish lips or face, or fainting.
- Go to the ER if breathing is still hard 20 minutes after a treatment, or the ribs pull in with each breath.
- Call us now if rescue medicine is needed more often than every 4 hours, or wheezing is not better 20 minutes after a treatment.
- Book a visit if your child has no written asthma action plan or spacer, or has missed school because of breathing problems.
How Sun Pediatrics can help
Every physician at our practice is board certified, and we care for children from birth through 18. We give nebulizer treatments in the office, check oxygen levels, teach families how to use a nebulizer or spacer, and write asthma action plans so you know what to give and when to call.
If your child is wheezing or needs rescue medicine more often than usual, we hold same-day sick visits Monday through Friday, with in-office rapid tests for flu, RSV, strep, and COVID. Follow-ups work well by secure video visit. Families are welcome at our Marietta, East Cobb, and Alpharetta offices.

Frequently asked questions
Can a nebulizer help a baby with congestion?
Usually not. For a stuffy nose, saline drops and suction work better. Use a nebulizer only with medicine your doctor prescribed.
What is the best nebulizer for kids?
The best one is the one your child will use with a good mask seal. A standard jet nebulizer works well at home; a quieter mesh nebulizer is handy for travel or sleeping toddlers.
Is it safe to use a nebulizer on a newborn?
Only with a prescription and an infant mask, and only with the medicine and dose your doctor gave you.
Can I put saline in a nebulizer for my child?
Only if your pediatrician recommends it. Saline can trigger more coughing or wheezing in some children.
Do nebulizer treatments have side effects?
Albuterol often causes shakiness and a fast heartbeat for a short time. Call us if your child has a racing heartbeat that does not settle, chest pain, or seems very agitated.
