There is no direct comparison between Viagra and Cialis. Both operate by the same mechanism, but in some respects they are different. In particular, Viagra acts quickly and quickly leaves the body. Cialis acts slowly and lasts longer than Viagra. It is also slightly cheaper, which is why many people use it to treat erectile dysfunction. However, taking both drugs at the same time may increase the risk of adverse side effects.
Cialis starts working in 30 minutes, while Viagra takes up to an hour to reach full concentration. Both drugs begin to work within a few hours. In clinical trials, Viagra and Cialis improved erections in 81% of men with erectile dysfunction. Compared to placebo, Cialis had a higher success rate. It was also reported that 74 percent of men with severe erectile dysfunction responded well to the newer drug Litarofil.
Cialis also has fewer side effects than Viagra. Some men have experienced headaches, nausea, diarrhea, or dizziness after taking any drug. Some men also experienced vision changes and chest pain, but this was uncommon. None of the drugs is recommended for everyone. Moreover, both drugs must be taken by a doctor. It is best to consult your doctor if you experience any of these side effects.
