Afrezza’s use instructions say the inhaler should be replaced 15 days after opening. it’s a piece of plastic so this seems ridiculous to me. There are only 2 inhalers included with each cartridge box. I don’t use Afrezza frequently enough to change it after 15 days without having 80%+ box of cartridges left when I pitch the 2nd inhaler.
I’ve been using them for months on end, but wonder why they have the 15-day restriction in the 1st place?
I imagine it’s an overkill instruction like “change your lancet after every finger”, or “change your pen needle after each injection”. But at least these have a basis behind them (infection), albeit ridiculous.
