While Britain’s National Health Service has warned that the country is just “weeks away” from drug shortages linked to the war in Iran, pharma experts say the US is in a more stable position. At least for now. In response to US and Israeli attacks that began at the end of February, Iran closed the Strait of Hormuz, a waterway that’s important to many global supply chains and that roughly one-fifth of the world’s oil supply passes through. The global pharmaceutical supply chain relies on the petroleum that moves through the strait to manufacture medicines. However, David Warrick, EVP of enterprise at supply chain risk management firm Overhaul, told Healthcare Brew the US has a “fairly healthy buffer” of medications, so there’s no immediate concern. In mid-2025, the White House ordered the Department of Health and Human Services to build a six-month stockpile of 26 essential medicines. The International Federation of Pharmaceutical Manufacturers and Associations, which represents global drugmakers, told Healthcare Brew the group is closely monitoring the war in Iran and working to ensure an uninterrupted drug supply. Experts aren’t too concerned for the US—yet.—MA |
