There have been rare reports of priapism (prolonged and painful erections lasting more than 6 hours) with the use of oral PDE5 inhibitors such as vardenafil, sildenafil and tadalafil. Patients with blood cell diseases such as sickle cell anemia, leukemia, and multiple myeloma have higher than normal risks of developing priapism. Priapism untreated can cause injury to the penis tissue and lead to permanent loss of potency. If there is prolonged erection (longer than 4 hours), immediate medical assistance should be sought.

May use treatment only when desired They then reviewed studies on the safety of sildenafil (brand name Viagra) for patients with congestive heart failure. Because medications for erectile dysfunction also have an effect on blood vessels and circulation, they can be dangerous when mixed with heart medications, sometimes leading to fatal drops in blood pressure. The largest published trial of sildenafil evaluated efficacy based on the previously validated International Index of Erectile Function.21 In 312 men receiving sildenafil, mean scores for the frequency of penetration and maintenance of erections after penetration increased significantly.17 A clinically significant dose-response relationship was also demonstrated: erection appropriate for intercourse was attained in 72 percent of the men receiving 25 mg, 80 percent of those receiving 50 mg, and 85 percent of men those given 100 mg of sildenafil.17 looking for cheap viagra online? canadian pharmacy viagra for sale
