Eli Lilly runs first prescription drug ad in Google AI Mode
Ad-intelligence firm Adthena said it tracked an Eli Lilly ad for an oral GLP-1 weight-loss pill running inside a Google AI Mode answer on October 11, against the query “glp-1 medication” — the first live pharma ad it has found in the surface. Per Adthena, the ad never names the drug and instead directs searchers to ask a doctor about prescription pill options, an unbranded format that sidesteps the risk disclosures a named-drug ad would carry under FDA rules; Google confirmed to Adweek the next day that it had begun testing prescription drug ads in AI Mode and AI Overviews, limited to the U.S. Adthena also said Google Ads reporting gives advertisers no way to separate AI Mode or AI Overviews placements from the rest of their search activity, and that none of the roughly 50,000 U.S. AI Mode ad placements it tracked in August carried a prescription brand.
Why it matters: It's the first confirmed live sighting of Google's new pharma-ad test, landing within a day of Google itself confirming the test — and the ad's unbranded format shows an advertiser already working around standard drug-ad disclosure rules.
