Counterfeit drugs: A major issue for vulnerable citizens throughout the world and in the United States.

Instruct clinicians on counterfeit drugs and their implications for patient health. Counterfeit drugs imperil patients around the globe, and their penetration into the United States, Canada, and Western Europe is only increasing over time. In addition to inserting counterfeit drugs in the legitimate drug supply, rogue Internet pharmacies and consumer purchases while traveling abroad allow counterfeit drugs to endanger patients. Pharmacists need to understand the nature and severity of the issue and directly counter it through personal actions to secure a legitimate drug supply, such as by using verified distributors and examining the shipment packaging, product packaging, the bottle, and the label for evidence to determine if it is counterfeit or has been tampered with. They can also indirectly counter it through patient education and by working with other key stakeholders in the health care system. Given the risk to patients, pharmacists have an important role to play in limiting patient use of counterfeit drugs.
