Blue pills for sleep
We absolutely hate it when companies have similar-looking packages for two products that are completely different from each other. This not only causes consumers to pick up the wrong stuff accidentally, but if they have both at home, they end up using one in place of the other. The worst offenders are companies that make stuff for your health with look-alike packaging.
For instance, feast your eyes on this packaging atrocity. Why would Rexall package a sleeping aid and a laxative in identical orange boxes? Do they really expect us to read the label before taking the pill? Change your packaging, Rexall!
