Another question from a new extender user. I am trying to decrease side effects of Symbicort so just started using an extender. I am so used to the "blast" when you don't use an extender that I am wondering if I am getting the full dose. Or does the medication get stuck in the extender? I know this sounds stupid but how does the extender make the medication get deeper into the airway? If you study it physically it seems as if it decreases the depth of deposit of the medication. What am I not understanding? I asked the RT at Rehab and he couldn't give me a good explanation. Maybe one of our RT's here can jump in and explain? Thanks in advance.
