In May this year, as part of the annual Operation Pangea, an Interpol-led international internet week of action targeting the illegal online sale of counterfeit and unlicensed medicines, the Singapore Health Sciences Authority (HSA) seized more than 56,000 units of counterfeit health products, with a total estimated street value of more than US$320,000. More than 60% of the counterfeit health products seized were sexual enhancement drugs, some of which contained undeclared potent Western medicinal ingredients like tadalafil.
