Taking Viagra doesn't cause new or worsening ED. However, Viagra can sometimes cause priapism, which is a long-lasting and sometimes painful erection.

The problem is their effect on arteries. All arteries, not just those in the penis, generate nitric oxide, so any artery can widen in response to Viagra, Levitra, or Cialis, causing blood pressure to drop temporarily by 5-8 mmHg, even in healthy men.
Sildenafil tablets for erectile dysfunction come in different strengths ranging from 25mg to 100mg. The usual dose is 50mg, when you need it. Do not take it more than once a day. The dose can be increased to 100mg or decreased to 25mg depending on its effect.

Technically, Viagra, or its generic form, sildenafil, can be taken daily, but it's not always the best choice. Viagra works by opening up your blood vessels and increasing the amount of blood in your penis, making it easier to get an erection.
When used in women, Viagra is thought to raise blood flow to the genitals so that there's more sensitivity and stimulation. Studies have shown that Viagra may provide a benefit for women having difficulty with sexual arousal — since it may help them respond better to sexual stimulation.
