Counterfeit, fake, adulterated or falsified drugs and pharmaceuticals, could be branded or generic drugs, excipients and active substances (in drugs and vaccines), medical supplies and devices, etc, intended to pass as the original. Counterfeits are always inferior in terms of quality, safety and efficacy compared to the original pharmaceuticals, and subsequently, they pose an unpredictable risk to public health and lead to loss of confidence in medicines, healthcare providers, and health systems. In the decades before the outbreak of the COVID-19 pandemic, a constant trend of increased trafficking was reported. However, the pandemic created a combination of public health emergency, economic distress, and misinformation-driven panic that made problematic the access and supply of high quality essential medicines and health products, and pushed consumers and vendors even more towards counterfeit pharmaceuticals. This contribution aims to review the trends in counterfeit drugs and pharmaceuticals trafficking, the health impact of their use, as well as, measures and actions implemented to restrict their proliferation, before and during COVID-19 pandemic; the relative recommendations, the expressed perspectives and the existing limitations are thoroughly discussed.
