On April 7, 2010, the US Food and Drug Administration issued Warning Letters to six U.S. based medical spas and a company in Brazil for making false or misleading statements on their Web sites about drugs they claim will eliminate fat in a procedure called "lipodissolve", or for otherwise misbranding lipodissolve products. "We are concerned that these companies are misleading consumers", said Janet Woodcock, M.D., director of the FDA's Center for Drug Evaluation and Research. "It is important for anyone who is considering this voluntary procedure to understand that the products used to perform lipodissolve procedures are not approved by the FDA for fat removal".
