CIAVOR 5 is a treatment for adult men with erectile dysfunction. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity. CIAVOR 5 has been shown to significantly improve the ability of obtaining a hard erect penis suitable for sexual activity. CIAVOR 5 contains the active substance tadalafil which belongs to a group of medicines called Phosphodiesterase type 5 inhibitors. Following sexual stimulation CIAVOR 5 works by helping the blood vessels in your penis to relax, allowing the flow of blood into your penis. The result of this is improved erectile function. CIAVOR 5 will not help you if you do not have erectile dysfunction. It is important to note that CIAVOR 5 does not work if there is no sexual stimulation. You and your partner will need to engage in foreplay, just as you would if you were not taking a medicine for erectile dysfunction.
