US Pharm. 2009;34(11):5.Silver Spring, MD — The FDA warned consumers about purchasing any products over the Internet that claim to diagnose, prevent, treat, or cure the H1N1 influenza virus. The warning comes after the FDA recently purchased and analyzed several products represented online as Tamiflu (oseltamivir) that may pose risks to patients. One of the orders, which arrived in an unmarked envelope with a postmark from India, consisted of unlabeled white tablets taped between two pieces of paper. When analyzed by the FDA, the tablets were found to contain talc and acetaminophen, but none of the active ingredient oseltamivir. The Web site disappeared shortly after the FDA placed the order.
