The Food and Drug Administration (FDA) warns not to use alcohol-based hand sanitizers that contain methanol or wood alcohol, as they can be toxic if absorbed through the skin leading to nausea, vomiting, headache, blurred vision, blindness, seizures, coma, nervous system damage, and even death. The FDA is working to prevent these products from entering the United States and is coordinating with manufacturers to recall such products. Food and Drug Administration, July 2020
