USA. Health Nutrition (RMA Laboratories), under advice from the US FDA is warning consumers not to purchase or consume the product known as VIGA or VIGA FOR WOMEN. These products are sold as dietary supplements, without a medical prescription and have been found to contain sildenafil. Sildenafil is a prescription drug and may have serious health risks if used without medical supervision, particularly if the users are also on concurrent nitrate therapy. The interaction between nitrates and sildenafil can result in profound and life-threatening lowering of blood pressure. The use of nitrates is therefore an absolute contraindication for sildenafil users. Consumers who have purchased VIGA or VIGA FOR WOMEN tablets are urged to immediately discontinue their use and to return them to their place of purchase or directly to Health Nutrition (RMA Laboratories).
