Written by In contrast to Viagra, which has sildenafil citrate as its main ingredient, Cialis has tadalafil, which is also a PDE5 inhibitor. PDE5 inhibitors are used mainly in the treatment of erectile dysfunction, and Cialis is the third ED prescription pill that was allowed to be sold in the United States, after Viagra and Levitra.
While the effects of taking Cialis are the same as that of Viagra, because the main ingredients are different, the costs are different too. If you look up the prices of Cialis and Viagra online, you will find a little difference between the two, but the dosages of Cialis are at 20mg while Viagra is at 50 and 100mg. It is important not to mix up the dosages too, and cutting up a Viagra pill to reduce it to the 20mg of a Cialis pill does not produce the same results.
You can get Cialis a little cheaper than Viagra, but not by much. But it can be legally sold in the United States, and that is saying something, compared to the other kinds of cures for erectile dysfunction out in the market today. There is herbal Viagra, Viagra soft tabs and professional Viagra, which, while it may or may not be as effective for erectile dysfunction, is nonetheless still illegal inside the United States.
You might be confused about the availability of these pills, but in short, there are only three pills that can be sold in the US for erectile dysfunction, and that is Viagra, Levitra and Cialis.
