FDA has received 23 reports of serious health problems ranging from jaundice and elevated liver enzymes, an indicator of potential liver injury, to liver damage requiring liver transplant. One death due to liver failure has been reported to the FDA.
Liver injury, although rare, was reported by patients at the doses of Hydroxycut recommended on the bottle. Symptoms of liver injury include jaundice (yellowing of the skin or whites of the eyes) and brown urine. Other symptoms include nausea, vomiting, light-colored stools, excessive fatigue, weakness, stomach or abdominal pain, itching, and loss of appetite.
Other health problems reported include seizures; cardiovascular disorders; and rhabdomyolysis, a type of muscle damage that can lead to other serious health problems such as kidney failure.
FDA urges consumers to stop using Hydroxycut products in order to avoid any undue risk, says Linda Katz, M.D., interim chief medical officer of FDA's Center for Food Safety and Applied Nutrition. "Adverse events are rare, but exist," Katz says. "Consumers should consult a physician or other health care professional if they are experiencing symptoms possibly associated with these products.
