Getting a flu vaccine is the best way to prevent the influenza disease and complications from that illness. The U.S. Food and Drug Administration (FDA) is urging consumers need to be vigilant and avoid dishonest sellers of fraudulent and unproven products that have not been evaluated or approved by the FDA. Many of these fraudulent products are sold online and in retail stores and may be labeled as dietary supplements, foods, hand sanitizers, nasal sprays or devices. Protect yourself and your family by being on the lookout for potentially fraudulent flu and antiviral products being sold without a prescription. For more information visit the FDA website.
