A child with asthma? Keep inhalers primed and clean
A properly cared for inhaler results in more consistent and effective treatment for children with asthma.
You can maximize the use of your child’s asthma inhalers—and make sure he or she is getting the proper amount of medicine—by priming and cleaning them regularly.
Priming (releasing one or more sprays into the air) ensures your child gets an accurate dose of medication. Regular cleaning is also important to keep inhalers working properly, since residue can accumulate around the exit hole, impeding or even blocking the spray completely.
Start with a shake
Before using a new inhaler, shake it really well, three to four times. This mixes the ingredients in the canister so each dose contains the right blend of medication and propellant.
You also should shake the inhaler if it hasn’t been used in a while. Medications may have separated from the other ingredients in the canister and the metering chamber.
Prime your asthma inhaler
A new inhaler or one that hasn’t been used in a while may not deliver the correct amount of medicine with the first puff, so it needs to be primed.
To prime an inhaler, spray some “waste” puffs into the air after shaking (away from the face, of course). This will help make sure your dose contains the labeled amount of medication.
Our pediatric patients use a combination of controller and reliever inhalers. Following is a list of the most common asthma medications for both types of inhalers and the appropriate number of waste puffs for each one.

Before using a new inhaler, or if you have concerns about a used one, be sure to check the priming instructions—even if you have a child with asthma and have been using inhalers for years. Each one comes with its own set of recommendations. And if you have any questions, be sure to contact a PHS asthma educator.
Does your child have asthma or use inhalers? What experiences have you had with inhalers? Any tips or advice to share? We’d love to hear from you.
