Prescription-drug prices are difficult to reduce to a slogan. They vary by product, patent status, insurance coverage and whether researchers measure posted or net prices. The strongest available peer-country studies do not support describing America as the cheapest market overall.

Research commissioned by HHS and carried out by RAND examined international data and found that US prices across brand and generic drugs averaged roughly 2.78 times comparator-country prices in 2022. Brand-name medicines had particularly large gaps, while unbranded generics could be cheaper in the United States. This is the evidence against the blanket lowest-price claim.

The comparison is not a real-time census of every pharmacy in 2026. New price negotiations may change specific drugs. The appropriate verdict is that the sweeping claim is not established by the reliable comparative record—not that every American prescription costs more than its foreign equivalent.
