What does Viagra do?
As you've probably heard, Viagra (Sildenafil) is used to treat impotence in men who either can't have or can't maintain erections. On the market since March 1998, it's one of the most commercially successful drugs ever launched, with millions of prescriptions filled at a cost of more than $ 1 billion during the first year alone. It even has the blessing of the Vatican, on the ground that it can strengthen families.
Just as important, here's what Viagra can't do. It isn't an aphrodisiac; it can't get you aroused when you're not interested. And it's not a performance-enhancer. If you're healthy, Viagra won't give you a faster or harder erection or help you last longer. In fact, in healthy men it can even cause a painful, long-lasting erection (a condition called priapism) that may lead to impotence if it isn't treated quickly.
What happens if I miss a dose?
Viagra is used as needed, so you are not likely to miss a dose.
If you miss a dose of Revatio, take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take extra medicine to make up the missed dose.
Erectile dysfunction (ED or (male) impotence) is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis. There are various underlying causes, such as cardiovascular leakage and diabetes, many of which are medically treatable.
Erectile dysfunction, tied closely as it is to cultural notions of potency, success and masculinity, can have devastating psychological consequences including feelings of shame, loss or inadequacy; often unnecessary since in most cases the matter can be helped. There is a strong culture of silence and inability to discuss the matter. In fact around 1 in 10 men will experience recurring impotence problems at some point in their lives.
The causes of erectile dysfunction may be physiological or psychological. Physiologically, erection is a hydraulic mechanism based upon blood entering and being retained in the penis, and there are various ways in which this can be impeded, most of which are amenable to treatment. Psychological impotence is where erection or penetration fails due to thoughts or feelings (psychological reasons) rather than physical impossibility; this can often be helped. Notably in psychological impotence there is a very strong placebo effect
