Viagra, also known by its non-branded name sildenafil, lasts for up to 4 hours after you have taken it. This can vary upon different factors such as your age, diet, existing health conditions and the dosage you have taken. The effects of Viagra usually last for around hours. Levels peak around the 1 hour mark, but this can vary, depending on whether you have eaten beforehand. It takes around hours for blood levels to halve, and the effectiveness of Viagra starts to decline around this time. One hour after taking Viagra, an erection can last for 33 minutes, after 8 hours, an erection can last for 23 minutes, and after 12 hours, an erection can last for up to 16 minutes. This can vary from person to person, in fact, for most people, the effects of Viagra will wear off after hours.
