Speak of Viagra and you’ll see that the majority –which includes all ages–definitely knows what the name means and what it is for.  Here’s why: more and more and more doctor’s office visits by men are made to seek treatment for erectile dysfunction and the rate has increased rapidly from 8 in 1000 visits in the mid-eighties to 22 out of 1000 visits in 1999.  So the condition is pretty common as you see.  But many do not know that there are two other major brands of pills for erectile dysfunction which boast the same action: Levitra and Cialis.   All three drugs for male impotence work the same way by blocking the enzyme PDE-5, resulting in the erection. But each one has slight chemical differences, which means, that you have a choice and that one may work better for you than another will.

For example, Levitra is the drug uses a smaller dose, but starts working faster than Viagra.  It is known that Viagra works for about 4 or 5 hours, but it can also be effective up to 12 hours taking into account individual peculiarities of every person. Levitra’s action lasts for about the same time, but Cialis has a great advantage over the other two drugs: it remains effective for 24 hours and even up to 36 hours for different patients, which is why it got the nickname, “the weekend pill”.

Each pill has its own advantages and yet almost all the drugs have side effects too. The well-known Viagra, the same as Levitra and Cialis can cause headaches, upset stomach, flushing, vision tint and a stuffy nose.  Yet Levitra seems to have fewer or at least less strong side effects. But it all depends on the individual qualities of health and organism of every patient.  You should also remember that before you begin to take one of the 3 medications for ED, you should also consider lifestyle factors that may play a role in your ED, such as exercise diet and smoking.
