1. what doxadura xl is and what it is used for

The active substance in your tablets, doxazosin, belongs to a group of medicines known as alpha-1 antagonists. Doxadura XL is used to treat the following conditions:

• – High blood pressure. If left uncontrolled, high blood pressure can increase the risk of heart disease or stroke.

Doxadura XL works by widening your blood vessels making it easier for your heart to pump blood through them. This helps to lower raised blood pressure and reduce the risk of heart disease.

• – Symptoms of benign prostatic hyperplasia (BPH). This condition causes enlargement of the prostate gland, which is just underneath the bladder in men. This makes it difficult to pass urine.

Doxadura XL works by relaxing muscle around the bladder exit and prostate gland, making it easier to pass urine.

2. what you need to know before you take doxadura xl

Do not take Doxadura XL

• – if you are allergic to doxazosin, to quinazolines (e.g. prazosin, terazosin) which is the chemical family of medicines to which doxazosin belongs, or any of the other ingredients of this medicine (in section 6). Allergic reactions may be, for example, itching, reddening of the skin or difficulty breathing – if you have low blood pressure (hypotension) or have had a fall in blood pressure on standing up which caused dizziness, light-headedness or fainting (orthostatic hypotension)

• – if you have or have had any form of obstruction of the digestive tract

• – if you have benign prostatic hyperplasia (BPH) and additionally suffer from a blockage of your upper urinary tract, chronic urinary infections or bladder stones

• – if you have an overflowing bladder, almost no production of urine (anuria) or if your kidneys fail to function properly (progressive renal insufficiency)

• – if you are breast-feeding.

Warnings and precautions

Talk to your doctor or pharmacist before taking Doxadura XL

• – if you suffer from liver disease

• – if you have suffered acute heart disease such as heart failure

• – dizziness, weakness and in rare occasions fainting may occur, especially when you first start taking this medicine. You should therefore be careful in the beginning of treatment, and avoid situations that could lead to injury if these symptoms occur.

Your physicians will advise you what to do in the event of postural hypotensive symptoms (a decrease in blood pressure with symptoms when changing positions, e.g. from lying down or sitting to standing).

You should not be concerned if occasionally you observe remains in the stools that look like a tablet. This is because Doxadura XL has a non-absorbable coating that is designed to control the release of the medicine over a prolonged period.

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

Children and adolescents

Doxadura XL is not recommended for use in children or adolescents below 18 years as safety and efficacy have not been established.

Other medicines and Doxadura XL

Please tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Tell your doctor if you are already taking any of the following:

• – Non-steroidal anti-inflammatory drugs (NSAIDs), e.g. ibuprofen

• – Other medicines used in the treatment of high blood pressure

• – Oestrogens (female hormones)

• – Dopamine, ephedrine, adrenaline, metaraminol, methoxamine, phenylephrine (medicines called sympathomimetics used e.g. for the treatment of heart problems, low blood pressure, asthma, or congestion of the nose)

• – Doxazosin and the so-called phosphodiesterase-5 inhibitors (e.g. 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 lightheadedness, 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. Furthermore, it is recommended to respect a 6-hour time interval from intake of doxazosin and phosphodiesterase-5 inhibitors.
