Tadalafil is an oral drug that is used for treating impotence (the inability to attain or maintain a penile erection). Erection of the penis is caused by the filling of the penis with blood. Tadalafil is in a class of medications called phosphodiesterase (PDE) inhibitors. It works to treat erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. Below we listed products that contian Tadalafil as active ingredient. All of them are in stock and ready for shipping to Australia.
