What GOPTEN is used for

Gopten is used to treat high blood pressure (hypertension) and also to treat some heart conditions.

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 lead to serious health problems, including stroke, heart disease and kidney failure. Gopten helps to lower your blood pressure.

Gopten belongs to a group of medicines called Angiotensin Converting Enzyme (ACE) inhibitors. It works by relaxing your blood vessels, making it easier for blood to move around your body. This helps lower blood pressure and increase the supply of blood and oxygen to the heart.

Your doctor may prescribe Gopten for another reason. Ask your doctor if you have any questions about why Gopten has been prescribed for you.

Gopten is only available with a doctor's prescription.

Gopten is not addictive.

Gopten is not recommended for use in children as there have been no studies of its effects in children.

How to take GOPTEN

How much to take

Your doctor will tell you how many capsules you will need to take each day. This depends on your condition and whether or not you are taking any other medicines.

The usual dosage is one or two capsules taken once daily, up to a maximum of 4mg (two 2mg capsules) once daily.

Dosage for older people over 65 years.

The usual starting dose for older people is less than that for younger adults. Your doctor will adjust the dose of Gopten, depending on how quickly your kidneys and liver can remove it from your body.

Follow all directions given to you by your doctor and pharmacist carefully.

These directions may differ from the information contained in this leaflet.

If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

How to take it

Swallow Gopten with water.

When to take it

Take Gopten at about the same time each day.

Taking your capsules at the same time each day will have the best effect. It will also help you remember when to take the capsules.

It does not matter if you take Gopten before, during or after food.

If you need to take an antacid, take it at least 2 hours before or 2 hours after your dose of Gopten.

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 medicine as you would normally.

Do not take a double dose to make up for the dose that you missed.

This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

How long to take it

Gopten helps control your condition, but does not cure it.

Therefore you must take Gopten every day. Continue taking the capsules for as long as your doctor tells you.

If you take too much (overdose)

Immediately telephone your doctor or pharmacist or the Poisons Information Centre (Australia telephone 13 11 26 or New Zealand 0800 POISON or 0800 764 766), or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much Gopten. Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

If you take too much Gopten, you may feel dizzy, light-headed, weak, have palpitations or faint.

While you are using GOPTEN

Things you must do

Have your blood pressure checked when your doctor says, to make sure Gopten is working.

If you become pregnant while taking Gopten tell your doctor immediately.

If you feel light-headed or dizzy after taking your first dose of Gopten, or when your dose is increased, tell your doctor immediately.

Tell your doctor if you have excessive vomiting and/or diarrhoea while taking Gopten.

You may lose too much water and salt and your blood pressure may drop too much.

Drink plenty of water when you are using Gopten, especially if you sweat a lot (e.g. during hot weather or exercise).

If you do not drink enough water while taking Gopten, you may faint or feel light-headed or sick. This is because your blood pressure is dropping suddenly. If you continue to feel unwell, tell your doctor.

Tell any other doctors, dentists, and pharmacists who are treating you that you are taking Gopten.

If you are about to be started on any new medicines, tell your doctor, dentist or pharmacist that you are taking Gopten.

If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are taking Gopten.

If you are about to have any blood tests, tell your doctor that you are taking Gopten.

Gopten may interfere with the results of some tests.

Go to your doctor regularly for a check-up.

Your doctor may occasionally do a blood test to check your potassium level in the blood and to see how your kidneys are working.

Things you must not do

Do not give Gopten to anyone else, even if they have the same condition as you.

Do not take Gopten to treat any other complaints unless your doctor tells you to.

Do not stop taking Gopten, or lower the dosage, without checking with your doctor.

Things to be careful of

If you feel light-headed, dizzy or faint, get up slowly when getting out of bed or standing up.

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. If this problem continues or gets worse, talk to your doctor.

Be careful driving or operating machinery until you know how Gopten affects you.

Gopten may cause dizziness, light-headedness or tiredness in some people. Make sure you know how you react to Gopten before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or light-headed.

If this occurs, do not drive.

If you drink alcohol, dizziness or light-headedness may be worse.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Gopten.
