Reading cough-and-cold season in Hanoi pharmacies
How independent pharmacies can spot early velocity shifts in cough, cold, and related OTCs before the main winter rush.
Cough-and-cold demand in Hanoi rarely arrives as a single spike. It builds through cooler evenings, school terms, and short bursts of rain that keep people indoors. Pharmacies that only watch last year’s calendar often miss the first two weeks of movement.
Start with weekly unit velocity on core SKUs: adult syrups, paediatric packs, lozenges, and saline sprays. A modest rise across three consecutive weeks is more useful than a single busy Saturday. Pair that with stockouts on the top three lines—those gaps often signal demand earlier than a full month report.
Watch complementary baskets. When tissue, vitamin C, and throat pastilles rise together, the cold season is usually underway even if the weather still feels mild. Note any supplier promotions that might inflate one week’s numbers without reflecting true patient demand.
For a practical floor response, deepen facings on proven movers before expanding fringe flavours. Keep one clear endcap for the season rather than scattering cold products across multiple bays. That keeps staff recommendations consistent and reduces lost sales when a preferred pack runs out.
If you operate more than one store, compare districts. Hai Ba Trung traffic patterns differ from outer wards; a city-centre store may see office workers earlier, while neighbourhood pharmacies follow school calendars more closely. Share a simple weekly note between stores so buying stays coordinated.
