About doxazosin

Doxazosin belongs to a group of medicines known as alpha-blockers. It works by blocking the action of certain nerve impulses. This blocking action is useful in two different medical conditions. It is used to help control the symptoms of prostate gland enlargement, and it also reduces blood pressure in people with יתר לחץ דם.

The prostate gland commonly becomes larger in older men. Prostate gland enlargement is also called benign prostatic hyperplasia (BPH). It can cause problems with passing urine, such as 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. Doxazosin works by relaxing the muscles around your bladder and prostate so that you can pass urine more easily.

In people with high blood pressure, doxazosin works by relaxing blood vessel walls. This allows blood and oxygen to circulate more freely around your body and lowers your blood pressure.

Doxazosin is available as a standard tablet and also as a modified-release tablet. Modified-release tablets have the letters 'XL' after their brand name - these release doxazosin more slowly and evenly throughout the course of the day.

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 doxazosin it is important that your doctor knows:

• אם את בהריון, מנסה להיכנס להריון או מניקה.

• If you ever feel dizzy or faint when you stand up, or if you have ever fainted after passing urine.

• If you are due to have cataract eye surgery.

• אם יש לך בעיות בתפקוד הכבד שלך.

• If you have been told you have heart failure.

• אם אי פעם הייתה לך תגובה אלרגית לתרופה.

• אם אתה נוטל תרופות אחרות כלשהן. זה כולל כל תרופה שאתה נוטל שניתן לרכוש ללא מרשם, כמו גם תרופות צמחיות ומשלימות.

• Before you start this treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about doxazosin and will provide you with a full list of the side-effects which you may experience from taking it.

• There are several strengths of doxazosin tablet. When you first start the treatment, your doctor may give you a low dose which will then later be increased. This allows your doctor to make sure that you have the dose that helps your condition and avoids any unwanted symptoms.

• Your first dose of doxazosin may make you feel faint, so it is important that you take this dose at bedtime. If you feel dizzy or weary, or if you start sweating, remain lying down until these symptoms have gone.

• Take doxazosin once each day. After your first dose (which should be taken at bedtime), try to take your doses at the same time of day each day - you can generally choose a time of day that suits you. This will help you to avoid missing doses.

• Swallow the tablet with a drink of water. You can take doxazosin before or after meals.

• If you have been given modified-release tablets (these have 'XL' after the brand name), these should be swallowed whole. Do not chew or break the tablets to help you swallow.

• If you forget to take a dose, take it as soon as you remember. If you do not remember until the following day, skip the missed dose - do not take two doses together to make up for a forgotten dose.

• Doxazosin can make you feel dizzy, particularly when you first start taking it. Make sure your reactions are normal before you drive or before using tools or machines which would be dangerous if you are not fully alert.

• You are advised not to drink alcohol while you are on doxazosin. Alcohol will increase the side-effects of doxazosin, such as feeling faint and dizzy.

• נסה לשמור על הפגישות הקבועות שלך עם הרופא. זה כדי שהרופא יוכל לבדוק את ההתקדמות שלך.

• If you are having an operation or medical treatment, tell the person carrying out the treatment that you are taking doxazosin. 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 eye surgeon that you are on doxazosin. This is because an eye problem known as 'floppy iris syndrome' has developed in some people taking medicines similar to doxazosin, so your doctor may advise you to stop taking it for a short while.

• If you buy any medicines check with a pharmacist that they are suitable to take with your other medicines. Some anti-inflammatory painkillers (called NSAIDs) can reduce the blood pressure-lowering effect of doxazosin.

Along 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 doxazosin. 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.

• שמור את כל התרופות מחוץ להישג ידם וראייתם של ילדים.
