Crisis-Proofing Formularies: How Pharmacies Can Prepare For Shortages Before Winter
Active drug shortages in the US climbed to 227 in the second quarter of 2026, the third consecutive quarterly increase. For pharmacies heading into flu, RSV, and cough and cold season, the timing compounds the risk. Winter demand surges compress the window for reactive sourcing decisions, and pharmacies that build formulary resilience ahead of Q4 are better positioned to keep shelves stocked when patients need them most.
What's Driving The Rise In Drug Shortages Heading Into Winter?
Sole source manufacturer concentration sits at the center of the problem. Nearly half of all new shortages reported in 2026 involve a single manufacturer, meaning one facility disruption, contamination finding, or quality hold can remove a medication from the national supply, with no backup source to absorb demand.
Chemotherapy drugs, imaging contrast agents, and controlled substances have been especially exposed this year. The pattern reflects a structural vulnerability across the generic manufacturing base, one that can also affect seasonal respiratory medications once demand spikes.
Which Medications Are Most Exposed This Season?
Antibiotics, antivirals, and other medications tied to seasonal respiratory illness typically see utilization spikes as flu and cold cases rise through Q4 and into January, adding pressure to categories already prone to disruption.
There's been notable progress on the antiviral side. In June 2026, the FDA approved the first generic version of balaxavir marboxil, expanding treatment and post-exposure prophylaxis options ahead of the 2026-2027 flu season. Broader generic availability for high-demand seasonal drugs like this helps diversify the supply base and gives pharmacies more sourcing flexibility heading into peak cold and allergy season.
How Can Pharmacies Build A Winter-Ready Formulary?
Preparation is most effective as a proactive process built ahead of peak demand:
Identify high-velocity, high-impact medications for safety stock, focusing resources on items where a stockout would most directly affect patient care.
Qualify backup suppliers before shortages hit, since sourcing alternatives during active disruption limits options and drives up costs.
Monitor active shortage lists at a regular cadence to catch early warning signs before a product disappears from shelves.
Work with pharmaceutical partners who can provide transparency into supply availability and pricing stability across the formulary.
FAQs
What causes most drug shortages?
Most new shortages stem from sole-source manufacturing, where a single facility supplies the entire market. A quality issue, contamination finding, or production halt at that site can remove a medication from national supply, with no immediate backup available.
When should pharmacies start preparing for winter shortages?
Preparation works best when it begins ahead of Q4 demand, well before cold and flu season peaks. Early safety stock planning and supplier qualification give pharmacies more sourcing options than waiting until a shortage is already active.
How can pharmacies reduce shortage risk?
Diversifying suppliers, maintaining safety stock for high-impact medications, and monitoring shortage lists regularly all reduce exposure. Partnering with a distributor that offers transparent supply visibility adds another layer of protection during the peak season.
