1.    WHAT DOXAZOSIN IS AND WHAT IT IS USED FOR

Doxazosin 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.

Doxazosin can be 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, Doxazosin is taken to treat poor and/or frequent passing of urine. This is common in patients with an enlarged prostate gland. Doxazosin works by relaxing muscle around the bladder exit and prostate gland so urine is passed more easily.

2.    WHAT YOU NEED TO KNOW BEFORE YOU TAKE DOXAZOSIN

“ Do not take Doxazosin:

-    If you have had an allergic (hypersensitive) reaction in the past to Doxazosin tablets, the active ingredient doxazosin, other types of quinazolines (such as prazosin or terazosin) or any of the other ingredients listed in section 6. This may have been itching, reddening of the skin or difficulty in breathing.

-    If you are breast-feeding

-    If you are under 18 years of age, as safety and efficacy have not yet been established

-    If you have a history of a condition known as ‘orthostatic hypotension’ which is 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 have an enlarged prostate gland with one of the following: any kind of congestion or blockage in your urinary tract, a long standing infection of the urinary tract or you have bladder stones.

-    If you have overflow incontinence (you do not feel the urge to urinate), or anuria (your body is not producing any urine) with or without kidney problems.

□ Warnings and precautions:

Talk to your doctor or pharmacist or nurse before taking this medicine

The following are reasons why doxazosin may not be suitable for you:

-    If you are pregnant or trying to become pregnant

^_If you have liver disease_

-    If you are also taking other medicines

-    If you have heart disease

If you are undergoing eye surgery because of cataract (cloudiness of the lens) please inform your eye specialist before the operation that you are using or have previously used doxazosin. This is because doxazosin may cause complications during the surgery which can be managed if your specialist is prepared in advance.

When you start to take doxazosin you may experience faintness or dizziness caused by low blood pressure, when getting up from sitting or lying down. If you feel faint or dizzy, you should sit or lie down until you feel better and avoid situations where you might fall or hurt yourself. This is more likely to happen when you are starting treatment or increasing the dose, your doctor may want to measure your blood pressure regularly at the start of therapy to reduce the possibility of these effects happening.

□    Other medicines and Doxazosin:

You should always tell your doctor if you are taking or have recently taken any other medicine, even those not prescribed, because they might interact with doxazosin.

It is particularly important to tell your doctor or pharmacist if you are taking the following medications:

•    medicines used to treat high blood pressure

•    phoshodiesterase inhibitors, such as sildenafil (Viagra), tadalafil and vardenafil for erectile dysfunction

There are some medicines that may interact with doxazosin tablets:

-    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.

-    Doxazosin may lower your blood pressure even more if you are already taking other medicines to treat your high blood pressure such as terazosin and prazosin.

DOXAZOSIN with food and drink:

Doxazosin Tablets can be taken with or without food.

□    Pregnancy and breast-feeding and fertility:

-    Pregnancy

The safety of using doxazosin during pregnancy has not been established. If you are pregnant or trying to become pregnant speak to your doctor and he/she will decide if doxazosin is suitable for you.
