Upjohn Co., Kalamazoo, Mich., has begun what it says is the U.S. pharmaceutical industry's first consumer ads for impotence awareness. The campaign will not mention a product, but coincides with the recent availability of its Caverject Sterile Powder, the first prescription medication cleared for marketing as a treatment for impotence. Ads are scheduled for more than 30 national publications, beginning this week. Radio spots will run in selected cities as a test beginning next month. The ads address facts about male impotence, including causes and treatability. The ads include a business reply card and a toll-free number for more information. Agency is DraftDirect Worldwide, New York.
