@FranandZoeI'd take my pharmacists' answers and use either med, probably both.
First of all, the date on the expired med is most likely a sell by date, no?
Of course, what I don't know at all is how you'll know whether the "cold" med is effective. Will there be a quick and recoverable effect? Knowing that would affect my decision. I just know I have gotten to old age here following advice from my medical professionals - but I don't take Liptor. I do take a sratin though, and I know I've used "expired'" and the vascular surgeon I see regularly has seen no change in the last 3 years. That's my hurrah.
