What is in this leaflet

What it is used for
Aldomet lowers high blood pressure, which doctors call hypertension.
Everyone has blood pressure. This pressure helps get your blood all around your body. Your blood pressure may be different at different times of the day, depending on how busy or worried you are. You have hypertension (high blood pressure) when your blood pressure stays higher than is needed, even when you are calm and relaxed.
There are usually no symptoms of hypertension. The only way of knowing that you have hypertension is to have your blood pressure checked on a regular basis. If high blood pressure is not treated it can lead to serious health problems. You may feel fine and have no symptoms, but eventually hypertension can cause stroke, heart disease and kidney failure. Aldomet helps to lower your blood pressure.
Aldomet works by controlling impulses along certain nerve pathways. As a result, it relaxes and widens blood vessels so that blood passes through them more easily. This helps to lower blood pressure.
Ask your doctor if you have any questions about why Aldomet has been prescribed for you.
Your doctor may have prescribed it for another purpose.
This medicine is only available with a doctor's prescription.
There is no evidence that it is addictive.

Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.
Some medicines should not be taken with Aldomet. These include:
- medicines used to treat depression such as moclobemide, phenelzine and tranylcypromine.
Some medicines and Aldomet may interfere with each other. These include:
- other medicines for high blood pressure

- iron supplements and multivitamins containing iron.
These medicines may be affected by Aldomet or may affect how well it works. You may need different amounts of your medicine, or you may need to take different medicines.
Your doctor or pharmacist has more information on medicines to be careful with or to avoid while taking Aldomet.
How to take it
Follow all directions given to you by your doctor carefully.
They may differ from the information contained in this leaflet.
How much to take
Your doctor will tell you how many tablets you need to take each day.
This depends on your condition and whether you are taking any other medicines.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
How to take it
Swallow the tablets whole with a glass of water or other liquid.
When to take it
Take your medicine at about the same time each day, unless your doctor tells you otherwise.
If you are taking it twice a day, take the tablets at breakfast time and dinner time - that is, about 12 hours apart.
If you are taking it three times a day, take the tablets about 8 hours apart.
Taking your tablets at the same time each day will have the best effect on your blood pressure. It will also help you remember when to take the tablets.
It does not matter whether you take Aldomet before or after food.
How long to take it
Continue taking Aldomet for as long as your doctor tells you.
This medicine helps to control your high blood pressure but does not cure it. Therefore it must be taken every day.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking your tablets as you would normally.
If you are not sure whether to skip the dose, talk to your doctor or pharmacist.
Do not take a double dose to make up for the dose that you missed.
If you have trouble remembering to take your tablets, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much Aldomet. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too many tablets, you will probably feel light-headed and dizzy or you may faint. You may also feel very drowsy, weak, may have a slow heart rate, be constipated, have abdominal bloating, gas in the stomach or bowel, diarrhoea, nausea or vomiting.
While you are taking it
Things you must do
Have your blood pressure checked when your doctor says to make sure Aldomet is working.
If you feel light-headed, dizzy or faint, get up slowly when getting out of bed or standing up.
You may feel light-headed or dizzy when you begin to take Aldomet or if the dose is increased. This is because your blood pressure is falling suddenly. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. The problem usually goes away after the first few days.
If you are about to be started on any new medicine tell your doctor and pharmacist that you are taking Aldomet.
If you plan to have surgery (even at the dentist) that needs a general anaesthetic, tell your doctor or dentist that you are taking Aldomet.
Your blood pressure may drop suddenly.
If you are having blood and urine tests, tell your doctor you are taking Aldomet.
Aldomet may interfere with some of these tests giving incorrect results.
If you develop fever, tell your doctor.
Your doctor may need to do some blood tests to make sure Aldomet is not affecting your liver or blood.
Tell your doctor if you are to have a blood transfusion, that you are taking Aldomet or have taken it in the past few months.
Aldomet may interfere with the tests used to decide which blood group you receive.
Make sure you drink enough water during exercise and hot weather when you are taking Aldomet, especially if you sweat a lot.
If you do not drink enough water while taking it, you may faint or feel light-headed or sick. This is because your body doesn't have enough fluid and your blood pressure is low. If you continue to feel unwell, tell your doctor.
Things you must not do
Do not give Aldomet to anyone else, even if they have the same condition as you.
Things to be careful of
Be careful driving or operating machinery until you know how Aldomet affects you.
Aldomet may cause dizziness, light headedness, drowsiness or sleepiness, especially after the first few doses and if the dose is increased. Make sure you know how you react to it before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or drowsy. If you drink alcohol, dizziness or drowsiness may be worse.
Things that would be helpful for your blood pressure
Some self help measures suggested below may help your condition. Talk to your doctor or pharmacist about these measures and for more information.
Alcohol - your doctor may advise you to limit your alcohol intake.
Diet - eat a healthy diet which includes plenty of fresh vegetables, fruit, bread, cereals and fish. Also eat less fat and sugar.
Exercise - regular exercise helps to reduce blood pressure and helps the heart get fitter, but it is important not to overdo it. Walking is good exercise, but try to find a route that is fairly flat.
Before starting any exercise, ask your doctor about the best kind of programme for you.
Salt - your doctor may advise you to watch the amount of salt in your diet. To reduce your salt intake you should avoid using salt in cooking or at the table.
Smoking - your doctor may advise you to stop smoking or at least cut down.
Weight - your doctor may suggest losing some weight to help lower your blood pressure. Some people may need a dietician's help to lose weight.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Aldomet.
Aldomet helps most people with high blood pressure, but it may have unwanted side effects in a few people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
These are all mild side effects of Aldomet and may disappear with continued treatment. They may also occur if the dose is increased.

- fever shortly after starting to take Aldomet, for example, within the first 3 months
- yellowing of the skin and eyes, also called jaundice

- numbness, tingling, pain, or weakness in your hands or feet

These are all serious side effects. You may need urgent medical attention. Serious side effects are rare.
