Viagra was developed and originally marketed by the pharmaceutical company Pfizer, and until 2013 Pfizer was the only company allowed selling it. When Pfizerâ€™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 place a odear on TollFree No. +1-855-255-5514â€¦.
Sildenafil contains exactly the same active ingredient as Viagra (sildenafil citrate), and works in the same way. However, because it is the generic version of the medicine, rather than the brand, Sildenafil is considerably cheaper.
Levitra will last for a similar amount of time as Viagra (four to six hours). The main difference to Viagra is that Levitra tends to be less affected by food or alcohol so can be taken with meals. There is also some evidence that Levitra is more effective in diabetics than other erectile dysfunction medicines.
The effects of Cialis Tadalafil last much longer than those for Viagra or Levitra (up to 36 hours) so many men prefer it as involves less planning. The downside is that if you do experience side effects these can last for longer too.
Like Levitra, Cialis is not affected much by food, so can be taken after a meal. Alcohol, however, may reduce its effects.
Is Viagra, Cialis or Levitra best for me?
Different erectile dysfunction medicines suit different people, but it is difficult to tell which one will be best for you until you have tried them all.
While a particular erectile dysfunction medicine may not work for you first time round, we recommend taking it at least eight times before giving up and trying another. This is because it can often take this long to determine whether or not a medicine is right for you.
We also often suggest that men initially try all three erectile dysfunction medicines to see which is best for them, and we offer a starter pack of Viagra, Levitra and Cialis for those suitable.
