Most pills today are 'blister' packed so if the 'blister' is intact you know it has not been touched.
Yes, you are right Jaysay, if you return drugs to the pharmacy unused they are destroyed even if they are in date.
This is because the pharmacy cannot guarantee what conditions they have been kept in...temperature etc.....so they figure it is safer to destroy them.

A great bugbear of mine was always..... when people go into hospital and they already have a supply of perfectly good meds that they were taking at home......why can't they continue to take their own meds in hospital? After all, they are told to bring all their current medications into hospital with them.
That would save hospitals an untold amount of money.
