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.

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.
