Your Child's Asthma: Inhaled Medications

Your child will most likely have at least one inhaled asthma medication. The medication is delivered with an inhaler or a nebulizer. It is very important that inhalers and nebulizers are used correctly in order for your child to get the correct amount of medication. The best way to make sure the devices are used correctly is for you or your child to show the health care provider, nurse, or pharmacist how you use them. If needed, the provider, nurse or pharmacist can then offer additional instructions.

Inhalers with Spacers

An inhaler discharges medication in a fine spray. A spacer is a tube with a mouthpiece that can be attached to the inhaler. It helps more medication gets into the lungs. To use an inhaler with a spacer, follow the package instructions. If you have questions about the right way to use the inhaler, ask your child’s health care provider.

Instead of a mouthpiece, a mask with a spacer is used for infants and toddlers. Your child's healthcare provider can show you the best way to use an inhaler with a mask.

A nebulizer turns medication into a fine mist. The medication is delivered through a mouthpiece or mask that fits on the face. Getting the full dose takes from 7 to 15 minutes. Nebulizers are sometimes used by infants or toddlers. They are usually not needed if a child is able to use an inhaler with spacer properly.
