Cialis vs Viagra - Which Side Are You?
Ten years after Viagra's release, Cialis came out in 2003 to compete with Viagra, the then sole erectile dysfunction medicine in the market. With a few track records under its belt, how could Cialis fare vs. Viagra?
Cialis works the same way as Viagra: both inhibits the enzyme that prevents production of hormones responsible for penile erection during sexual intercouse. They are both called PDE-5 inhibitor. However, their similarities end here. In terms of side effects and longevity of effect, the two varies.
Cialis is known to cause muscle pains while with Viagra, a few men complain of having blue-like vision after a few hours of taking it. However, these two erectile dysfunction medicine shares common side effects such as headache, flushing of the face and nasal congestion.
In the longevity department, it has been found that Cialis works overtime (in as long as 36 hours) while Viagra lasts for four hours only. This is the reason why Cialis has been called the "weekender" because you can have an active sex life during the weekends with a single dose of Cialis taken on a Friday night.
Now seeing these comparisons, which side are you in the Cialis vs. Viagra showdown? Honestly, these two drugs haven't been compared head to head. This Cialis vs. Viagra comparison is based only on independent studies conducted on each of these two medicines. What is best for you would largely depend upon your needs and how your body would react to the chemical components of the medicine. Since these two erectile dysfunction medicines have been found to be effective treatment for sexual dysfunctions in men, you will not lose whether you chose Cialis over Viagra or Viagra over Cialis.
