Sildenafil is used to treat erectile dysfunction and should only be used under the supervision of a health care practitioner. Products authorized for sale containing sildenafil indicate that it should never be used by individuals taking any kind of nitrate drug (e.g. nitroglycerine) as it can cause potentially life-threatening low blood pressure.
