About Tadalafil

This medicine contains the active substance tadalafil. This medicine belongs to a group of medicines
called phosphodiesterase type 5 inhibitors.

The 2.5 mg, 5 mg, 10 mg, and 20 mg tablets of this medicine are used to treat adult men with erectile dysfunction. This is the case when a man cannot achieve an erection or maintain an erection suitable for sexual activity for long enough.

Tadalafil has been shown to greatly improve erection ability. After sexual stimulation, this drug helps to relax the blood vessels in the penis, allowing blood to flow into your penis. This improves your erection.

This medicine will not help if you do not have erectile dysfunction. It is important to know that this medicine will not work if there is no sexual stimulation.

시알리스 Tadalafil is also prescribed for other conditions (benign prostatic hyperplasia, increased blood pressure in the pulmonary arteries). You will find more information about this in the package leaflet.
