New Cleaning Instructions for Reliever Puffers (Asmol/Ventolin/Zempreon)

If you’ve purchased an asthma reliever puffer lately, you’ll see it comes with a dose counter. With a new dose counter, you need to clean asthma reliever puffers weekly to keep them working effectively. That includes Ventolin/Asmol/Zempreon – which are all brands available over the counter.

Whilst the dose counter is useful to see how much you’re using, we hope to support your use of the device with this change in place. We understand you have probably never cleaned your reliever devices before now. And that you probably have multiple relievers around the house, so if in doubt – clean them all together, each week. Spacer devices should also be cleaned at least monthly (see here)

We’ve had a variety of feedback about this change (which has brought this to our attention so thank you). We are talking to manufacturers who also want to hear from you, especially if you keep having trouble with your device – see their contact details below.

For medicine that is essential to many people with asthma, it is critical that you follow manufacturer’s instructions for regular cleaning.

Asthma Australia understands that many people wouldn’t have looked at the new dose counter information leaflet in the medication box, however, we encourage you to become familiar with it particularly with this new change.
