In late July 2026, the Czech Ministry of Health announced an emergency delivery of 1,000 tamoxifen packages to address a year-long shortage that began when the manufacturer halted supplies in 2023. The ministry imposed prescription limits to prevent hoarding and advised that brief treatment interruptions of up to 14 days were not serious.

By early August, the response expanded as nearly 6,000 packages were secured for pharmacies, intended to provide a two-month course for approximately 1,250 patients and raise national stocks above normal weekly consumption. Health Minister Adam Vojtěch stated, “We have done everything to make treatment available as soon as possible.” To facilitate this, the ministry utilized emergency measures and recent changes to national medicines law to allow the use of unregistered tamoxifen approved in other EU states and permitted the repackaging of existing stock to match prescribed durations.

Major pharmacy chains, including Dr. Max and BENU, have begun receiving limited initial shipments. For instance, Dr. Max reported receiving 900 packs distributed across approximately 243 pharmacies based on historical demand. The Masaryk Memorial Cancer Institute also confirmed it has sufficient stock in its pharmacy. While these acute crisis management tools are functioning, experts have noted that new legislation has struggled to prevent such shortages or ensure suppliers maintain adequate emergency stocks to avoid disruptions.
