Vitaros is said to work in around five to fifteen minutes, and the erection-inducing effect may last up to a couple of hours, or until you orgasm. It should work even for psychogenic dysfunction as dopamine-response is less of an issue.
In some ways Vitaros seems ideal: if discretion is important, you just visit the loo before undressing, and you’re ready a few minutes later, - assuming it works. And, if you’re not ‘invited in’, unlike Viagra, you’ve not wasted £8.
Vitaros was approved in Canada in 2010, and should be available there through Abbott Laboratories. The current, much postponed, launch date is November 2013. It was approved in Europe in June 2013, and planned launch date in the UK is January 2014.
