Apex e-chamber spacer device - user issues with valve and round mouthpiece

23 May 2016

Monitoring finishes 26 November 2016

Medsafe has received a number of reports of issues relating to the use of the Apex e-chamber spacer device. The main issues described are:

  • the valve in the e-chamber is not opening as intended
  • swing gate valve is ineffective unless held in exactly the correct position which is very difficult when using the device with children
  • difficulties encountered using the round mouthpiece which allows some of the spray to escape

Products Affected

Apex e-chamber spacer

The e-chamber spacers are used to help overcome the co-ordination problems people may have when using inhalers.

Additional Information

e-chambers are intended to slow the delivery of medication which then allows greater delivery of medication to the lungs.

These spacer devices are funded by PHARMAC.

Regulator Actions

Medsafe is continuing to monitor the rate and pattern of occurrence of these issues.
