Generic Cialis Soft (Tadalafil Soft) is a phosphodiesterase inhibitor used to treat sexual disfunction problems such as impotence or erectile dysfunction. In combination with sexual stimulation, this medicine works by helping the blood flow into the penis to achieve and maintain an erection. This medicine is not intended for use in women or children.
