I am often asked which is the best of the three most common erectile dysfunction treatments: Viagra, Levitra or Cialis. Viagra is the most well-known of the three as it has been around for over 15 years. There is no simple answer to this question, as some men find one treatment works better for them than the others. This means that a lot is known about its effects and side effects. It works within an hour of taking a tablet, and is best taken on an empty stomach. The effects of Viagra will last for four to six hours. Viagra was developed and originally marketed by the pharmaceutical company Pfizer, and until 2013 Pfizer was the only company allowed to sell it. When Pfizer’s patent on Viagra expired, the market was open for other companies to produce the medicine, albeit under its generic name Sildenafil, rather than the brand name Viagra. Sildenafil contains exactly the same active ingredient as Viagra (sildenafil citrate), and works in the same way. Weighing the benefits and risks of Levitra versus Cialis requires some basic knowledge of each. A brief comparison of Levitra (Vardenafil) versus Cialis (Tadalafil) can be made by examining how they can be used (‘as needed’ for either or daily for Cialis), the time it takes for them to work, the length of time they continue to work, the restrictions on how they can be taken, the contraindications to their use, and the side effects each of them might cause. Though similar, ED medications have different effects and side effects. Levitra (Vardenafil) has a relatively rapid onset compared to Cialis (Tadalafil). Levitra can be effective in as little as 1 hour, while Cialis might not take effect for 2 hours, though for some patients these medicines can work more rapidly. Levitra will be out of the body in about 6 to 8 hours while Cialis can work for 24 to 36 hours. Levitra works about as quickly as Viagra and lasts about as long.

Tried intercourse 5 times but each time lost my erection after a few minutes so very disappointed Apparently they now have a new more recent and improved Levitra called Levitra professional so will try that and see if any better""I used 10mg Levitra for the first time. Certainly fuller and wider but not longer but still couldn't come. Tiny bit of face flushing but did have 1 large glass of white wine to relax before initiating anything. Very disappointing""Having tried 10mg which started to work I tried the 20mg. I received a sample of 20mg levitra x10 and wow, I'm switching. Had hard erections on and off all day and the next. Have recently tried Levitra professional and hardly worked at all yet they say this an improved version but did nothing for me at all.

Think if I had taken 20 mg it would have done the trick as 10mg too weak for me and much better than viagra or Cialis. Will definitely use again but 20mg next time""Experience is generally very positive. Weighing the benefits and risks of both Viagra and Levitra requires some basic knowledge of each. A comparison can be made by examining how they can be used, the time it takes for them to work, the length of time they work, the restrictions on how they can be taken, the contraindications to their use, and their side effects. Yet, one issue is rarely the sole factor men consider when taking a medication for erectile dysfunction. It is the interplay between a man’s social circumstances (and that of their partner), his need for a rapid onset of medication activity versus a prolonged duration of action, the individual reaction to the drug in terms of side effects, a person’s prior medical history, the other medications they take, and the very personal definition of what it means to achieve an erection satisfactory for sexual activity. Sildenafil (Viagra) can be effective in as little as 1 hour as can Vardenafil (Levitra), though for some patients these medicines can work more rapidly. In fact, some patients find that Viagra (sildenafil) and Levitra (vardenafil) can start to have an effect in 15 minutes. Nevertheless, each should be approached as reliably taking effect in 1 hour.
