I agree with isailtheseas and pat. Your list of "mixed pills" are OTC Remedies. It's probably not a good idea to do that for the reasons mentioned. I'll add another reason.
Aspirin is an OTC which is proven to be beneficial in Cardiac Emergencies when administered as First Aid. First Responders may ask if anyone has some Aspirin. You might have some, but if it's not in it's original container, it's not safe to administer a "mystery pill". Responders are trained that if it's not in it's original labled container it is out of the question.
Never "mix pills" that are prescription. It could get you into trouble, as mentioned, and even cost you your life in an Emergency. If you'd like that further explained, just PM me. I'm EMT (and IC F/A).
The other Posters are right, chances are no one will look at your pills. But that should not be your only concern. It is not wise to combine pills, period...prescription or non-prescription OTC. Paramedics know this well.
