The first thing that one might want to know about viagra is: how does it work? The first thing to understand about Viagra is that contrary to popular belief, it does not cause a man to become aroused. It is effective when you are aroused, but does not cause it. What Viagra does do is regulate the chemicals needed to have and maintain an erection. If you are not aroused already, Viagra will not help you. When you become aroused, the nervous system in your erectile tissue releases nitric oxide. Nitrus oxide provides stimulation to an enzyme that relaxes muscle cells. This allows blood to flow into the penis more easily which is what causes the penis to become erect and hard.
Another main concern people have is wondering if Viagra is safe. You should always consult a doctor before beginning to take any medication, including Viagra. People with high blood pressure or heart conditions should be extra sure to do this as it can slightly lower blood pressure and of course heart conditions are not to be taken lightly. There are, as with many medications, side effects to taking Viagra. Some of these side effects include facial flushing, headaches, stuffy nose, indigestion and some have even reported seeing with a blue tint to their vision. If you experience any of these side effects, you should let a doctor know and they will of course point you in the right direction as to if you can continue taking this medication or not. There are also medications that cannot be mixed with Viagra, so you should be sure to do proper research to find out which medications these are and always bring a list of your current medications to your doctors visit when you plan to discuss taking Viagra for the first time.
One of the most overlooked and important issues involving Viagra is that men are often embarrassed to bring the issue of impotence up with their doctor, and perhaps even more so, their spouse. It is important as a spouse to be sensitive and supportive when discussing Viagra (as this should be a joint decision) and it is important that men not feel inferior or in any way less of a man by having to rely on Viagra and similar medications for their sexual pleasure. It is suggested to speak to the spouse first, make the decision together as to whether or not you are willing to try Viagra or something similar to improve or maintain your sex life. Once this decision has been made, many men find it comforting to have their spouse accompany them to the doctor for moral support.
