1. WHAT DOXADURA IS AND WHAT IT IS USED FOR
Doxazosin is one of a group of medicines called alpha-blockers. DOXADURA tablets are used to treat high blood pressure (hypertension) or the symptoms caused by enlargement of the prostate gland in men. In patients taking DOXADURA to treat high blood pressure (hypertension) DOXADURA works by relaxing blood vessels so that blood passes through them more easily. This helps to lower blood pressure. In patients with enlargement of the prostate gland, DOXADURA is taken to treat frequent and/ or poor passing of urine. This is common in patients with enlargement of the prostate gland. DOXADURA 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 DOXADURA
Do not take DOXADURA if you:
Warnings and precautions:
Talk to your doctor or pharmacist before taking DOXADURA:
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 DOXADURA. This is because DOXADURA may cause complications during the surgery which can be managed if your specialist is prepared in advance. Before starting treatment with DOXADURA your doctor may perform tests to rule out other conditions such as prostate cancer that may cause the same symptoms as benign prostatic hyperplasia (enlargement of the prostate gland). Persistent painful erections may occur very rarely. If this happens you should contact a doctor immediately.
When you start to take DOXADURA 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. Your doctor may want to measure your blood pressure regularly at the start of therapy to reduce the possibility of these effects happening.
Children and adolescents
DOXADURA is not recommended for use in children or adolescents below 18 years as safety and efficacy have not yet been established. Benign prostate hyperplasia is not relevant in children.
Other medicines and DOXADURA:
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines including medicines obtained without a prescription.
There are some medicines that may interact with DOXADURA. Ask your doctor or pharmacist before use if you are taking any of these medicines as they may change the effect of DOXADURA. 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 medicines called PDE 5 inhibitors for the treatment of erectile dysfunction (impotence) with alpha-blockers e.g. sildenafil, tadalafil, vardenafil (please see Section “Warnings and precautions”). 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. DOXADURA may lower your blood pressure even more if you are already taking other medicines to treat high blood pressure.
DOXADURA with food and drink
Please refer to section 3.
Pregnancy, breast-feeding and fertility:
The safety of using DOXADURA during pregnancy has not been established. If you are pregnant or planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

3. HOW TO TAKE DOXADURA
Use in adults and elderly:
Always take DOXADURA exactly as your doctor has instructed you. You should check with your doctor or pharmacist if you are unsure. DOXADURA is usually taken once daily. DOXADURA may be taken in the morning or the evening. You can take your tablets before or after food.
You should take your tablets at the same time each day with a small amount of water. The initial dose of DOXADURA is 1mg once daily. Thereafter the dose may be gradually increased (within 1-2 weeks interval) to the recommended dose (2mg or 4mg daily). In some circumstances the dose may be increased to a maximum of 8mg daily if you are being treated for prostate enlargement, or to a maximum of 16mg if you are being treated for high blood pressure.
You have been given a calendar pack that will help you remember to take your tablets. If you are taking more than one tablet a day, you must ignore the marking for the day, printed on the back of the blister. Because high blood pressure is treated in order to prevent problems from arising, you may have no symptoms at all while taking DOXADURA. Even if this is so and you feel well, you should not stop taking your blood pressure medication unless instructed to by your doctor. Don't change the dose or stop taking the tablets without first checking with your doctor. Don't wait until your tablets are finished before seeing your doctor. If you have impression that the effect of DOXADURA is too strong or too weak, talk to your doctor or pharmacist.
Use in children and adolescents
The safety and efficacy of DOXADURA in children and adolescents have not been established.

Too many tablets at once may make you unwell. If several tablets are taken it may be dangerous.
