The following appeared in a local newspaper.
"People should not be misled by the advertising competition between Coldex
and Cold-Away, both popular over-the-counter cold medications that anyone
can purchase without a doctor's prescription. Each brand is accusing the
other of causing some well-known, unwanted side effect: Coldex is known to
contribute to existing high blood pressure and Cold-Away is known to cause
drowsiness. But the choice should be clear for most health-conscious
people: Cold-Away has been on the market for much longer and is used by
more hospitals than is Coldex. Clearly, Cold-Away is more effective."
