Why have I been prescribed Cardura XL?
- Cardura is one of a group of medicines called alpha-blockers. It is used to treat high blood pressure, or the symptoms caused by enlargement of the prostate gland in men.
How does it work?
- Cardura is used to treat high blood pressure (hypertension), by relaxing blood vessels so that blood passes through them more easily. This helps to lower blood pressure.
- In patients with an enlarged prostate gland, Cardura is taken to treat poor and/or frequent passing of urine. This is common in patients with an enlarged prostate gland. Cardura works by relaxing
- muscle around the bladder exit and prostate gland so urine is passed more easily.

Could it interact with other tablets?
There are some medicines that may interact with Cardura:
- Medicines for erectile dysfunction (impotence) such as sildenafil, tadalafil or vardenafil. Some patients who take alpha-blocker therapy for the treatment of high blood pressure or prostate enlargement may experience dizziness or light-headedness, which may be caused by low blood pressure upon sitting or standing up quickly. Certain patients have experienced these symptoms when taking drugs for erectile dysfunction (impotence) with alpha-blockers. In order to reduce the likelihood that these symptoms occur, you should be on a regular daily dose of your alpha blocker before you start drugs for erectile dysfunction.
