Ka, what we do, we dump all our medications in one bottle but we do carry the presciption/receipts with us, just in case. More practical than carrying a bunch of bottles that are all odd shapes and sizes.
If you're flying and bringing them in your carry-on then it may be the TSA who would be giving you a hard time. Having perscriptions with you and making sure the name on the bottle is your name is the best way to avoid any troubles. I've never heard of anyone having any major troubles regarding medication.
