It is important for clinicians prescribing these drugs to make the patient aware of the action of the drugs especially the fact that they do not result in an immediate erection, and that they do not cause an erection without sexual stimulation. There is frequently a great expectation when men begin using these drugs and it is wise to temper their enthusiasm and explain they do not work immediately, and may not work every time, but also let the patient know that if these drugs do not work, there are other options.
A man’s psychological state is clearly an essential consideration when addressing issues of sexual function. While ED that is purely psychological is not common, many men who experience difficulty with erections may develop anxiety or fear about being able to get an erection the next time they try. This anxiety may lead to a stress response involving activation of the sympathetic nervous system and release of adrenaline, which will tend to make it even more difficult to get an erection. Conflict with a partner (or the absence of a partner) will also tend to increase stress and potentially interfere with erectile function.
