Patient leaflet - Tadalafil 2.5 mg film-coated tablets

1. What Tadalafil film-coated tablets is and what it is used for

Tadalafil film-coated tablets contains the active substance tadalafil which belongs to a group of medicines called phosphodiesterase type 5 inhibitors.

Tadalafil film-coated tablets is used to treat adult men with erectile dysfunction. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity. Tadalafil film-coated tablets has been shown to significantly improve the ability of obtaining a hard erect penis suitable for sexual activity.

Following sexual stimulation Tadalafil film-coated tablets 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. Tadalafil film-coated tablets will not help you if you do not have erectile dysfunction.

It is important to note that Tadalafil film-coated tablets 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.

Tadalafil film-coated tablets improves blood flow to, and relaxes the muscles of, the prostate and bladder which may reduce symptoms of benign prostatic hyperplasia. Tadalafil film-coated tablets has been shown to improve these urinary symptoms as early as 1- 2 weeks after starting treatment.
