Tablets and prolonged-release tablets

The prostate gland commonly becomes larger in older men. O aumento da glândula prostática também é chamado de 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

Some 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:

  • Se você já se sentiu tonto ou desmaiou ao se levantar, ou se já desmaiou após urinar.

  • Se você precisar fazer cirurgia de catarata.

  • If you have any liver, kidney, or heart problems.

  • Se você já teve uma reação alérgica a um medicamento.

  • Se você estiver tomando ou usando qualquer outro medicamento. Isso inclui quaisquer medicamentos que você esteja tomando e que estejam disponíveis para compra sem receita médica, bem como medicamentos fitoterápicos e complementares.

How to take alfuzosin

  • Before 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.

  • Alfuzosin 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.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them.

Perguntas frequentes

Yes, there are two types of alfuzosin tablets: immediate-release and prolonged-release.
