So how does Viagra work?
There are many jokes and stupid stories you hear about Viagra and similar medications. Viagra only works effectively WHEN you are sexually aroused.
It also needs time to work. You need to be in the right situation and environment before you take Viagra. If you and your partner have decided to make love, then take it about an hour before.
This may not seem as spontaneous as you would like to be, but a drug like Viagra is usually only needed on a short term basis until your erections start to occur naturally again. Viagra, and other similar drugs, boost and enhance what is already there and works quite gently.
But how does it do this?
Without using too much medical jargon, Viagra boosts the blood supply to your penis so that when you are sexually aroused, it helps the erectile tissue to fill with blood. This, simply, is how you achieve and maintain an erection.
When you are no longer aroused, such as after sex, the blood supply will gradually decrease and your erection will go away. It's not true that after you have taken the drug, you will find yourself having embarrassing and unexplained erections at the most inconvenient times or inconvenient places. The drug just does not work in this way.
Is it safe for me to take it?
Good question and one you should ask before taking any prescription drug. See our page about the dangers of ED medications.
Before your doctor prescribes Viagra or any similar drug, he/she should ensure that it is safe for you to take it. If you have a medical history of heart problems, strokes, liver problems or high blood pressure, he/she may decide to give you something else.
Now, if your erectile dysfunction is due to something other than a physical problem, such as a psychological problem (this is more common than you think), Viagra could help, but you will need to discover and treat the causes of your anxiety or depression.
