There when the cough arrives
Weleda cough syrup is a well-known herbal cold remedy — all the more reason to be present at the decisive moment. With DOOH at the point of sale, the campaign reached customers right in the pharmacy, immediately before the purchase decision.


A pattern, not a lucky hit
more sales in the strongest campaign week — compared with similar pharmacies and drugstores running no campaign.
Peak value of the impact measurement · Source: IQVIA
Across the cold season, IQVIA compared sales at the Excom sites with the general market trend — what was counted was the till, not recall.
In every active campaign week sales ran above the market. The peak is therefore not an outlier, but the top of a consistent pattern.
In the middle of the cold season customers walk into the pharmacy with a specific need. The spot reaches them shortly before the purchase decision — and the specialist staff see it every day.
