OWhat Larbex XL is and what it is used for
The name of your medicine is Larbex XL 4 mg prolonged-release tablets. It belongs to a class of medicines called "alpha blockers." It can be used to treat high blood pressure or a condition called "Benign Prostatic Hyperplasia" (enlargement of the prostate).
If you suffer from high blood pressure, this can increase your risk of developing heart disease or having a stroke. Larbex XL lowers your blood pressure by relaxing your blood vessels which makes it easier for your heart to pump blood through them.
If you suffer from "Benign Prostatic Hyperplasia" (enlargement of the prostate) you may experience problems passing urine. In men the prostate gland is just below the bladder. If enlarged, it can make it more difficult for urine to flow out of your bladder. Larbex XL works by relaxing muscles around the bladder and prostate gland making it easier to pass urine.
Do not take Larbex XL:
• If you are allergic to doxazosin or other similar medicines which are in the same chemical class (e.g. prazosin, terazosin) or any of the other ingredients of this medicine (listed in section 6)
• If you have a orthostatic hypotension (a form of low blood pressure that causes you to feel dizzy or light-headed when you stand up from sitting or lying down)
• If you suffer from Benign Prostatic Hyperplasia and have:
• low blood pressure
• an obstruction to your upper urinary tract (tubes running between your kidneys and your bladder).
• chronic urinary tract infection • bladder stones
• If you have or have had a narrowing or blockage in your oesophagus (tube leading from your mouth to your stomach) or intestine or elsewhere in the digestive tract • If you are breast-feeding • Larbex XL should not be your only medicine in the treatment of • overflow incontinence (leakage of urine even when you feel no urge to urinate)
• if you have kidney problems or you produce little or no urine

• 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) such as sildenafil, tadalafil and vardenafil with alpha-blockers.
