Erectile dysfunction (impotence) is the inability to get and keep an erection firm enough for sex.
Having erection trouble from time to time isn’t necessarily a cause for concern. If erectile dysfunction is an ongoing issue, however, it can cause stress, affect your self-confidence and contribute to relationship problems. Problems getting or keeping an erection also can be a sign of an underlying health condition that needs treatment and a risk factor for heart disease down the road.
If you’re concerned about erectile dysfunction, talk to your doctor — even if you’re embarrassed. Sometimes, treating an underlying condition is enough to reverse erectile dysfunction. In other cases, medications or other direct treatments might be needed.
Although they work in similar ways, each oral medication has a slightly different chemical makeup. These minor differences affect the way each medication works, such as how quickly it takes effect and wears off, and the potential side effects. Your doctor will consider these factors as well as any health problems you have and possible interactions with other medications you take.
