Hi - thanks for chiming in here. Yours is a good question!
In my experience, many patients do quite well using a spacer, sometimes referred to as a 'valved holding chamber'. They tend to be most helpful for folks who, for whatever reason, have difficulty coordinating the release of medication (from the metered dose inhaler (MDI)) with the timing of their inhalation. Still, there are other patients who do just fine without the spacer.
This is a personal choice and will vary from patient to patient.
You may be aware that not all inhalers lend themselves to using spacers. You will have to determine if the medications you plan to use are capable of being used with a spacer device. Towards that end, in addition to asking your physician (who I understand hasn't gotten back to you yet), you may want to speak to your dispensing pharmacist. Pharmacists can be good sources of knowledge and information in this regard.
What do you think?
