Asthma Inhalers for Kids

Inhalers are a mainstay of asthma treatment, including for children who are old enough to know when to use one and how. This means they are able to remember to use a controller inhaler at specific times as prescribed by a doctor and to recognize the onset of an asthma attack that signals the need to use a rescue inhaler to nip wheezing and other symptoms in the bud.

Many, but not all, medications prescribed for adults with asthma are approved for children; some are appropriate only for kids 12 and over and not for younger children. If you have a child with asthma, their doctor will be able to determine which asthma inhalers are best for them based on their age and the severity of their asthma.

As a parent or caregiver, it will be useful for you to be familiar with the medications your child is prescribed, how they are best used, and any alternatives in the event a change in treatment becomes necessary.

Babies and very young children with asthma who aren't yet able to manage an inhaler typically received inhaled medications via a nebulizer—a machine that turns the medicine into a mist a little one can inhale through a mask or mouthpiece that fits over their nose and mouth.

Controller Inhalers

Controller inhalers for treating asthma contain corticosteroids, medications that prevent inflammation. By doing so, they ward off the swelling and excess mucus production that contribute to wheezing, difficulty breathing, and other common symptoms of asthma.

Inhaled corticosteroids (ICSs) are a important for asthma management. Because they are designed to prevent symptom flares and asthma attacks, they are used regularly. For most children, this means several times a day according to a prescribed schedule.

Some children 12 and over who have mild persistent asthma may not need to use an ICS everyday, according to asthma management guidelines updated by the National Institutes of Health in December 2020.

The recommendations state they might benefit either from using a low-dose ICS daily and a short-acting beta agonist (SABA) as needed to treat acute symptoms or from using an ICS and SABA at the same time only as needed. Your child's doctor will determine which approach is best suited for them.

When prescribing a controller inhaler for your child, their doctor likely will start with the lowest possible dose needed to control your child's symptoms.

Rescue Asthma Inhalers

Rescue inhalers are used as needed—when a child feels they're having an asthma attack or is about to based on the onset of symptoms (wheezing, chest tightness, shortness of breath, and so on). These inhalers are not meant to be used on a regular basis.

Rescue inhalers contain bronchodilator medications, which work by widening the bronchi (airways) that lead to the lungs. Narrowing of the airways, bronchoconstriction, is a key aspect of asthma along with inflammation, swelling, and excess mucus.

The rescue medication prescribed most often for children (and adults) is albuterol (a.k.a. salbutamol), is a short-acting beta-agonist that relaxes the airways so they can more easily widen. It is available under a number of brand names as well as a generic medication.

If your child seems to need their relief inhaler more than twice a week, let their pediatrician know. Frequent flare-ups of symptoms could be a sign your child's controller inhaler needs to be adjusted.

Combination Inhalers

For children 4 and over (as well as adults) who have moderate to severe persistent asthma (the two most severe categories of asthma), the NIH advises an inhaler containing two medications—an ICS and a drug called formoterol, a long-acting beta agonist (LABA).

This combination inhaler should be used as both a controller medication to be used daily and as a rescue therapy to relieve acute symptoms.

Types of Devices

There are two types of inhaler devices: metered-dose inhalers (MDIs) and dry powdered inhalers (DPIs).

While it's ideal to use the medication that controls asthma best, any medication is only as good as how well it is used. MDIs and DPIs each deliver medication a little differently and your child might feel that one device is easier to use than the other.


DPIs are breath-actuated, which means that medicine comes out as your child breathes in deeply and forcefully.

DPIs typically aren't prescribed until children are at least 5 or 6, as younger kids aren't able to inhale strongly enough to get a full dose of medication. Some older children dp prefer the level of control offered by DPIs.


MDIs release medication automatically and require coordinating a deep breath while operating the the inhaler. They contain hydrofluoroalkanes (HFAs), a substance that propels the medication with pressure.

(Another type of MDI, which uses chlorofluorocarbons (CFCs) to pressurize the medication, have been phased out by the Food and Drug Administration because of environmental concerns.)

Tips for Inhaler Use

Children may have some trouble learning to use an inhaler. It's important to call on their medical team for help teaching them the proper technique. For example, kids who use MDIs commonly make the mistake of breathing too fast instead of taking a slow, deep inhalation when using the medication.

Other issues to watch out for:

  • Blowing out into the inhaler instead of breathing in
  • Positioning the inhaler incorrectly
  • Forgetting to exhale fully before using the inhaler
  • Not holding their breath for about 10 seconds after inhaling the medicine
  • Forgetting to breathe out slowly afterward

A spacer is a small device that can be attached to an MDI inhaler. It has a holding chamber that keeps the medicine inside until a child takes a breath so they don't have to coordinate inhaling with activating the inhaler.Spacers come in different forms, including a mask for infants, toddlers, and children up to 4.

A Word From Verywell

An asthma action plan can help you and your child understand when the daily inhalers should be used and when the rescue inhalers are needed. Consult with your child's pediatrician if you need help explaining the importance of asthma management to your child in an age-appropriate way, and help evolve that understanding as they age.
