Vira-Block is intended for external use only; under absolutely no circumstances should it be taken internally. If a significant portion is accidentally ingested, call 911 or your local Poison Control Center immediately. Perhaps the most significant precaution we can suggest is that you understand that protecting your hands and skin from pathogens does not mean that you are completely free from them. Vira-Block can substantially reduce your overall risk of contracting disease, but it is not a panacea. Used properly and conscientiously, it will provide a meaningful measure of protection against the transmission of disease-causing micro-organisms from your environment to you.
