Key points

  • Use a counter to keep track of how many doses are left in your child’s inhaler.

How do I use this tool?

It is very difficult to tell if your child’s metered-dose inhaler (MDI) is empty by feel or sound alone. For inhaler medicines that do not have a dose counter on the device, you can use this tool to count how many doses are left.

Ask your child’s health-care provider how many doses (puffs) are in each of your child’s MDIs. Many MDIs have 200 or 120 puffs. There are counting tables below for both.

Print out this document and keep it next to your child’s medicine. Each time you give a puff, cross off the next number on the chart. When you are reach zero, it’s time to start a new inhaler.
