Viagra works by relaxing the muscles found in the walls of blood vessels and increasing blood flow to particular areas of the body. The primary indication of sildenafil is treatment of erectile dysfunction, enabling a man to maintain an erection and perform sexually. However, it is also used in the treatment of pulmonary arterial hypertension. The medication is typically taken orally, in the form of a blue, diamond-shaped pill. It should be taken approximately one hour before sexual activity, but it can be taken anywhere from four hours to thirty minutes before sexual activity. It is important to note that Viagra does not result in an erection without sexual stimulation. While Viagra has proven to be largely effective, it also comes with potential side effects. These can range from headaches, flushing, upset stomach, abnormal vision, to more serious effects such as sudden vision loss or hearing loss. Therefore, it is crucial that individuals considering this medication consult with their healthcare provider to discuss potential risks and benefits. Despite the potential side effects, Viagra has revolutionized the treatment of erectile dysfunction and has had a significant impact on sexual health for many individuals. As research continues, the future may hold even more promising developments in this field.
