About alfuzosin
Tipo de medicamento | An alpha-blocker |
Usado para | Enlargement of the prostate gland in men |
También llamado | Tablets: Xatral® |
Disponible como | Tablets and prolonged-release tablets |
The prostate gland commonly becomes larger in older men. El agrandamiento de la glándula prostática también se llama hiperplasia prostática benigna (HPB). The prostate is situated close to the bladder, so its enlargement can cause problems with passing urine. Common symptoms that are experienced are having to wait before your urine starts to flow, taking longer at the toilet, dribbling urine, and a feeling that your bladder is not quite empty.
Alfuzosin works by relaxing the muscles around your bladder and prostate gland so that you can pass urine more easily. There are two types of alfuzosin tablets available - immediate-release tablets and prolonged-release tablets. Immediate-release tablets need to be taken several times a day (typically, three times daily). Prolonged-release tablets are taken once a day as they release alfuzosin slowly throughout the day.
Before taking alfuzosin
Volver al contenidoSome medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking alfuzosin it is important that your doctor knows:
If you ever feel dizzy or faint when you stand up, or if you have ever fainted after passing urine.
If you need to have cataract eye surgery.
If you have any liver, kidney, or heart problems.
Si alguna vez has tenido una reacción alérgica a un medicamento.
Si está tomando o usando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

How to take alfuzosin
Volver al contenidoBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about alfuzosin and will provide you with a full list of the side-effects which you may experience from taking it.
Take alfuzosin exactly as your doctor tells you to. Swallow the tablet whole with a drink of water - do not break or chew the tablet.
Your first dose of alfuzosin may make you feel dizzy or faint, so it is important that you take it just before you go to bed. If you feel dizzy or weary, or if you start sweating, remain lying down until these symptoms have completely gone.
If you have been given immediate-release tablets (2.5 mg strength), the usual dose is one tablet three times each day, although this can vary. Your doctor will tell you what dose is right for you, and the directions will also be printed on the label of the pack of tablets to remind you about what the doctor said to you.
If you have been given prolonged-release tablets (these have 'XL' after the brand name), take one tablet every day. Take the tablet with a snack or just after eating a meal. After the first dose, you can take your dose at a time of day that best suits you, but try to take your doses at the same time of day each day. This will help you to remember to take the tablets regularly.
If you forget to take a dose, do not worry, just take the next dose when it is due and then carry on as before. Do not take two doses together to make up for a forgotten dose.

Volver al contenidoAlfuzosin can cause dizziness particularly when you first start taking it. This may affect your ability to drive. Make sure your reactions are normal before you drive or do things which would be dangerous if you were not fully alert.
Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress. Your doctor may want to take your blood pressure from time to time, particularly when you first start the treatment.
You are advised not to drink alcohol while you are on alfuzosin. Alcohol increases the risk of side-effects from alfuzosin, such as feeling faint or dizzy.
Consider reducing or stopping the amount of caffeine you drink (commonly found in tea, coffee and cola). Caffeine can make your symptoms worse, so drinking less of these things may benefit you.
If you are a smoker, stopping smoking may significantly improve your symptoms. This is because nicotine irritates the bladder. You can ask your doctor for advice on quitting.
If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking alfuzosin. This is because your blood pressure may drop suddenly if you have an anaesthetic. If you are having cataract surgery, it is particularly important that you tell your surgeon you are on alfuzosin. This is because an eye problem known as 'floppy iris syndrome' has developed in some people and your doctor may advise you to stop taking alfuzosin for a short while.

Can alfuzosin cause problems?
Volver al contenidoAlong with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with alfuzosin. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
Common alfuzosin side-effects (these affect fewer than 1 in 10 men) | ¿Qué puedo hacer si experimento esto? |
Feeling tired, dizzy, faint, or weak | No conduzca ni utilice herramientas o máquinas mientras esté afectado |
Feeling light-headed when getting up from a lying or sitting position | Getting up more slowly may help. If you begin to feel dizzy, lie down so that you do not faint, then sit for a few moments to prevent the dizziness returning |
Boca seca | Intenta masticar chicle sin azúcar o chupar caramelos sin azúcar |
Dolor de cabeza | Bebe mucha agua y pide a tu farmacéutico que te recomiende un analgésico adecuado. Si los dolores de cabeza continúan, informa a tu médico |
Feeling sick (nausea), diarrhoea, tummy (abdominal) pain | Stick to simple foods. Drink plenty of water to replace any lost fluids |
Si experimenta cualquier otro síntoma que crea que puede deberse a las tabletas, hable con su médico o farmacéutico para obtener más consejos.
