There are a lot of similarities between Viagra and Cialis. Both drugs were originally used to treat a totally different condition rather than erectile dysfunction. Viagra was used to treat a heart problem and Cialis was used to treat benign prostatic hyperplasia. But then after an unexpected side effect was discovered, that patients who took the drugs could gain a better and stronger erection, the two drugs have become the treatments for erectile dysfunction. And Viagra and Cialis are also similar in how the two help improve erectile dysfunction condition. Both drugs block PDE5 enzymes, a group of enzymes in the male body that block the blood flow into the penis when a man is aroused. So after taking Viagra or Cialis, a man can achieve a better, firmer and stronger erection and he can also last longer in bed. The erection is achieved naturally when a man is sexually stimulated and will end after he ejaculates.
But Cialis and Viagra have different components. When sildenafil is the main component of Viagra, tadalafil is the generic name of Cialis. And because of this difference, men who do not find Viagra useful or are allergic to Viagra can use Cialis and vice versa. And one thing to be aware about Cialis is that, among all the popular medications for erectile, ie Viagra and Levitra, Cialis is the only one that is offered as a once-daily medication .
Cialis was approved by the FDA as a treatment for erectile dysfunction in 2003. And in 2011, it was also approved as a treatment for benign prostatic hyperplasia. With the approval of the FDA and with years of researches and actual use on customers, Cialis is generally considered as a safe drug. However, some side effects have still been reported. Every man who is consider buying and using Cialis must be aware of the side effects of the drug.
A sudden drop in blood pressure is the most common reported side effect of Cialis. Actually, this is a side effect of all medications for erectile dysfunction. When a larger than normal amount of blood is pumped into the penis, a drop in blood pressure in the body is unavoidable. If you are normally healthy, there is nothing to worry about with this transient hypotension. But if you are having any kind of heart problem, this can lead to a stroke or heart attack. Due to the low blood pressure problem, you should avoid taking nitrates drugs when taking Cialis. Consuming nitrates drugs within 48 hours after taking Cialis could result to a life threatening low blood pressure. Also, besides the nitrates drugs, other drugs can shorten the half-life of Cialis and reduce the efficacy of Cialis. So generally, if you are having any heart problem or are taking any other drug, you should ask your doctor’s opinion first before using Cialis. And if you are using Cialis, you should also inform your doctor before he prescribes any new medication for you.
