The drink that was earlier promoted at Sexpo Sydney last year apparently contains vardenafil, a prescription-only substance, at levels above what was allowed in Australia. |
The mechanism of action of vardenafil is 9 times more selective than that of sildenafil, requiring lower doses. |
They contain similar active ingredients such as sildenafil, vardenafil and tadalafil. |
Grapefruit juice should also be avoided if you take ciclosporin, terfenadine, vardenafil or sirolimus. |
