Event Description

The manufacturer was made aware of an allegation by an end user that a prochamber valved holding chamber device was defective, causing medication to leak from her inhaler, thereby reducing the dosage.The user stated her oxygen saturation level was below 90%, and she experienced coughing, tightness and pain in the chest, and required prescription antibiotics.The user was prescribed 2 different inhalers (wixela inhub and other unknown).The user did not state clearly which inhaler did not fit in the prochamber, however the wixela inhaler would not be compatible with the prochamber due to its design and intended use as a maintenance inhaler.The user returned the prochamber to the store she purchased it from and it is not available for investigation.The prochamber is a valved holding chamber for the acute respiratory care setting.It is not required to use this chamber when using an inhaler, but can help to better deliver the inhaled medicine to the lungs.Based on the information available, the manufacturer concludes no further action is necessary.

Manufacturer Narrative

The manufacturer was contacted in reference to the voluntary field safety notice / recall notification related to the sound abatement foam in certain cpap, bipap and mechanical ventilator devices.Previously the manufacturer was made aware of an allegation by an end user that a prochamber valved holding chamber device was defective, causing medication to leak from her inhaler, thereby reducing the dosage.The user stated her oxygen saturation level was below 90%, and she experienced coughing, tightness and pain in the chest, and required prescription antibiotics.The user was prescribed 2 different inhalers (wixela inhub and other unknown).The user did not state clearly which inhaler did not fit in the prochamber, however the wixela inhaler would not be compatible with the prochamber due to its design and intended use as a maintenance inhaler.The user returned the prochamber to the store she purchased it from and it is not available for investigation.The prochamber is a valved holding chamber for the acute respiratory care setting.It is not required to use this chamber when using an inhaler, but can help to better deliver the inhaled medicine to the lungs.This notification was reviewed by the pms clinical expert due to the patient reporting "that the product did not fit her medication dispenser (a dry powder inhaler - wixela inhub) causing air leaks and not getting full amount of medication.Patient believes that the product is defective.She states she developed coughing, tightness, pain in her chest.She states that her o2 sats when taken were below 90%.The device may have caused or contributed to the reported event via user error.The ifu instructs patients to insert their mdi style inhaler into the product.The product is not intended to be used with dpi style inhalers.Dpi inhalers will not fit properly into the product.Even if the patient somehow was able to create a seal between the product and the inhaler, there is a risk for some medication residue (powder) to remain in the product chamber and therefore result in lesser treatment received by the patient.Repeated attempts to have the device and components returned for evaluation and investigation were unsuccessful.The manufacturer believes they will be unable to gather additional information.The manufacturer is submitting an updated report at this time.If pertinent information becomes available to the manufacturer at a later date, a follow-up report will be filed.Section b7 was missed to capture in initial report and was captured in this report and section h6 was updated in this report.
