Xatral XL (Alfuzosin)
How does it work?
Xatral XL prolonged-release tablets contain the active ingredient alfuzosin, which is a type of medicine called an alpha-blocker. It works by blocking alpha receptors that are found in the muscle in the prostate gland.
The prostate gland, which is found only in men, lies at the top of the tube connecting the bladder to the outside (urethra). The prostate gland often enlarges with advancing age (a condition called benign prostatic hyperplasia), pressing on the urethra and obstructing the flow of urine from the bladder. This can cause various urinary symptoms, such as difficulty passing urine.
Alfuzosin blocks alpha receptors in the muscle of the prostate gland, which causes the muscle in the prostate to relax. This allows urine to flow freely past the prostate and relieves the urinary symptoms.
Xatral XL tablets are prolonged-release tablets. They are designed to release the alfuzosin gradually as they pass through the stomach and intestine, so that a steady amount of medicine is absorbed into the bloodstream throughout the day.
What is it used for?
- Relieving the urinary symptoms of an enlarged prostate gland (benign prostatic hyperplasia).
- Acute retention of urine associated with an enlarged prostate gland, in men over 65 years of age. This medicine is taken for two to three days while a catheter is in place and for one day after the catheter has been removed.
How do I take it?
- One Xatral XL tablet should be taken once a day after a meal.
- The tablet should be swallowed whole with a drink of water and not chewed, broken or crushed, as this would stop the prolonged release action from working and cause all the medicine to be released at once. This is likely to result in increased side effects such as dizziness or fainting.
- The first dose of this medicine may cause dizziness, light-headedness or fainting. For this reason you should take your first dose just before going to bed at night.
- This medicine may cause dizziness, light-headedness or fainting, particularly when you first start taking it. Take care when moving from a lying down position to sitting or standing, particularly if you wake up in the night, until you know how this medicine affects you. If you feel dizzy, light-headed, sweaty or suddenly tired at any time during treatment, lie down until the symptoms have completely passed. Some people may find that drinking alcohol makes dizziness worse.
- As this medicine may cause fatigue and dizziness, you should take care when performing potentially hazardous activites, such as driving or operating machinery, until you know how this medicine affects you and are sure you can perform such activities safely.
- Your blood pressure should be monitored regularly during treatment with this medicine.
- If you are scheduled to have eye surgery for cataracts it is important to let your eye specialist know if you are or have been taking this medicine. This is because this type of medicine may make your pupil dilate poorly and the iris (the coloured circular part of the eye) become floppy during the procedure. The specialist needs to know if you have been taking this medicine so they can take appropriate precautions with the medicines and techniques they use during the surgery. You may be asked to stop taking this medicine for a period of time before cataract surgery. Check with your doctor.
- You may also be asked to stop taking this medicine before any other planned surgery where you will be given a general anaesthetic. Check with your doctor.
