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.

The word "impotence" may also be used to describe other problems that interfere with sexual intercourse and reproduction, such as lack of sexual desire and problems with ejaculation or orgasm. Using the term erectile dysfunction makes it clear that those other problems are not involved. Alprostadil is a hormone like substance that is referred to as prostaglandin E1, a known and potent vasodilator (improver of blood flow). Alprostadil has the power to directly effect the tissue that it comes into contact with.
