tylenolAmazon and Johnson & Johnson are in a tiff over the sale of damaged or expired J&J products including Tylenol and Rogaine by third-party merchants on Amazon’s site, according to a report this morning by the Wall Street Journal.

Dissatisfied with Amazon’s efforts to police its third-party sellers, the health-care products giant pulled some of its direct-sold products from Amazon earlier this year — including Tylenol, Band-Aids and baby products. J&J has started selling some products through Amazon again in recent days, but “the disagreement hasn’t been completely resolved,” the Journal reports.

J&J’s online “mystery shoppers” found cases of damaged and expired Tylenol and other J&J products from third-party sellers on Amazon. Other examples include a customer complaining about receiving expired bottles of Zyrtec allergy medication.

While they may be difficult to police, sales by third-party merchants account for a sizable portion of Amazon’s business. The company said in July that third-party sales amounted to 40 percent of products sold through the site.
