A record number of fake online pharmacies selling Covid-19-related products were shut down in May as part of a global operation.
More than 100,000 online markets offering illicit drugs were removed as part of Interpol Operation Pangea.
In Britain alone the seized drugs amounted to $ 13 million.
This was the largest operation since 2008, which took place between May 18 and 25, and 277 people from 92 countries were arrested. More than $ 20 million worth of pharmaceuticals were seized.
Fake or unauthorized Covid-19 testing packages accounted for more than half of all illegal medical devices seized worldwide.
UK authorities also removed more than 3,100 advertisements for the sale of unlicensed drugs as part of the operation.
About 43 UK-based websites were also shut down.
Interpol Secretary General Jurgen Stock said the sale of illegal drugs endangered the lives of “thousands” of victims.
“The online sale of illegal drugs continues to pose a threat to public safety, which is why operations such as Pangea remain essential in combating this global health disease,” he said.
“As the pandemic forced more people to shop online, criminals were quick to target these new customers.”
The global pharmaceutical industry is worth more than $ 1 trillion.
Supply chains extend from leading manufacturers in countries such as China and India, to packaging warehouses in Europe, South America or Asia, to distributors who ship medicines to every country in the world.
Last year, a BBC News investigation uncovered counterfeit drugs for sale in Africa, with counterfeiters exploiting growing gaps in the market.
