According to this article, LINK, from the European Urology journal, many men do not have good results from using Viagra because they are not informed how to use it. This study found that of 100 men who did not respond to Viagra:
– 45 never used the higher dose (100 mg)
– 32 took Viagra with a full stomach after a meal (it’s best with an empty stomach)
– 22 took the pill at the beginning of sexual activity! (You need 20-30 minutes for it to kick in)
– And 12 “were not aware that sexual stimulation was mandatory to achieve an erection” – in other words, they popped a pill and waited for an erection to just show up!
The investigators found with dose adjustments and better information, many of the men were able to get good results with Viagra.
