I just ordered Tiova from ADC and wondering why my current Spiriva comes in individual blister packs for each pill and the Tiova comes in a regular prescription bottle. With Spiriva, you are not supposed to even open the pack until ready to use it. So what is the reasoning for this as opposed to having the pills all in one container, like the Tiova? I wonder if the Tiova has a shorter shelf life because of the potential exposure to air and light. Any insight on this?
