I’m genuinely curious what is the concern? I routinely fill my t:slim cartridge with insulin that will last 5 or 6 days, and refill the cartridge when it empties, so I don’t understand why transferring insulin from one pod to another would be an issue. Insulin has preservatives. Some folks on MDI re-use their own needles a couple times before switching to a fresh one. I haven’t heard of problems caused by these practices (for folks with immune systems that are operational.) Is there something special about a pod that quickly makes insulin go bad?
