The Middle East conflict is disrupting the flow of critical medicines to the Gulf, threatening supply routes for cancer drugs and other treatments that require refrigeration. This has led to companies to reroute flights and find overland access into the region, as the Gulf relies heavily on imports and some medicines have short shelf lives and need strict cold-chain storage. Western drugmakers are seeking alternative routes into the Gulf and trucking some drugs overland from airports like Jeddah and Riyadh in Saudi Arabia. While there are currently no major shortages, this could change if the conflict drags on. The disruption could lead to shortages in oncology medicines, forcing patients to restart a course of therapy or see their cancer worsen.
