1. WHAT DOXAZOSIN IS AND WHAT IT IS USED FOR
Doxazosin belongs to the group known as vasodilators. These substances cause the blood vessel to widen, which reduces the blood pressure. Doxazosin can also reduce tension in the muscle tissues of the prostate and the urinary tract.
Doxazosin is used to treat:
• high blood pressure;
• symptoms of an enlarged prostate.
2. BEFORE YOU TAKE DOXAZOSIN
Do not take Doxazosin
• if you are allergic (hypersensitive) to doxazosin, other medicines from the same group (known as quinazolines, such as e.g. prazosin and terazosin) or any of the other ingredients of Doxazosin;
• 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 longstanding infection of the urinary tract or you have bladder stones.
• if you are breast-feeding
• if you have an enlarged prostate gland (benign prostatic hyperplasia) and have low blood pressure.
• 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.
Take special care with Doxazosin
Tell your doctor before you start to take this medicine if you:
• suffer from serious heart problems such as e.g. severely reduced cardiac function or a restrictive and painful sensation in the chest (angina pectoris);
• are on a strict low-salt diet;
• are using diuretics;
• have kidney or liver problems.
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.
Important information about Doxazosin
The likelihood of your blood pressure dropping too fast is greatest at the start of treatment or when the dosage is increased. You may observe this as dizziness or more rarely fainting when changing position. To reduce the risk of this happening, your doctor will check your blood pressure thoroughly at the start of treatment and when the dosage is increased. You should therefore avoid situations at the start of treatment in which dizziness or faintness could cause injury.
Doxazosin may also affect the results of some blood and urine tests. If you are due to have a blood or urine test make sure that you tell you are taking Doxazosin.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
• 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 high blood pressure such as terazosin and prazosin;
• nitrates (medicines for heart problems) such as nitroglycerine and isosorbide nitrate: these can exacerbate the hypotensive effect;
• certain painkillers for rheumatism (known as non-steroidal anti-inflammatory drugs) such as naproxen, ibuprofen or any other anti-inflamatory painkiller: these can reduce the hypotensive effect;
• medications that could also possibly affect the liver metabolism, e.g. cimetidine (a medicine for stomach problems);
Pregnancy and breast-feeding
Ask your doctor or pharmacist for advice before taking any medicine.
If you are pregnant or think you might be pregnant you should contact your doctor before taking Doxazosin. Doxazosin should only be used during pregnancy if your doctor decides that the benefits for the mother outweigh the possible risk for the foetus.
Do not breast feed while taking Doxazosin.
Driving and using machines
Doxazosin can sometimes cause dizziness or fainting. In such an event, you should exercise care during activities that require attentiveness, such as driving, operating machinery and working at heights. If you are unsure whether Doxazosin is having a negative effect on your ability to drive, discuss this with your doctor.
Important information about some of the ingredients of Doxazosin
This medicinal product contains lactose. If you have been told by your doctor that you have an intolerance to some sugars contact your doctor before taking this medicinal product.
3. HOW TO TAKE DOXAZOSIN
Always take Doxazosin exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
The usual dose is:
HIGH BLOOD PRESSURE
The initial dose is 1 mg daily (= 24 hours) in a single dose. After 1 to 2 weeks, the dose is generally increased to 2mg in a single daily dose (= 24 hours). This dose is also retained for 1 to 2 weeks. If necessary, the dosage can be further increased to 4, 8 or 16mg per day, until the desired reduction in blood pressure is achieved. The maximum daily dose is 16mg.
An initial dose should preferably be taken before going to bed; this means that any dizziness you may experience is less of a problem.
ENLARGED PROSTATE
The initial dose is 1 mg daily (= 24 hours) in a single dose. After this the usual dose is 2mg or 4mg daily. In some circumstances this may be increased to a maximum of 8mg daily.
The tablets should be taken as a single dose each day (= 24 hours). The tablets must be taken with plenty of water.
If you take more Doxazosin than you should
If you have taken more than the prescribed dose, you should consult your doctor and/or pharmacist immediately. If you feel extremely dizzy or think you might faint, you should lie down immediately with your head down.
If you forget to take Doxazosin
If you have forgotten to take a tablet, then skip it and take the next tablet at the usual time. You should check with your doctor or pharmacist if you are unsure. Do not take a double dose to make up for a forgotten tablet.
If you stop taking Doxazosin
If you suddenly stop taking doxazosin, the complaints you suffered prior to the start of treatment may recur. It is therefore better not to stop taking this medication suddenly. Your doctor will decrease the dosage gradually. You should always check with your doctor or pharmacist if you are unsure.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
