Consumer Medicine Information
What is in this leaflet

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking Norvapine against the benefits it is expected to have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.

What Norvapine is used for
What it does
Norvapine is used to:
- lower high blood pressure (hypertension)
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.
- treat angina pectoris.
Angina is a pain or uncomfortable feeling in the chest, often spreading to the arms or neck, and sometimes to the shoulders and back. The pain of angina is due to a shortage of oxygen to the heart.
Norvapine is not for the relief of a sudden attack of angina. Your doctor will give you other medication to treat this.
How it works
Norvapine belongs to a group of medicines called calcium channel blockers or calcium ion antagonists. They work by widening your blood vessels, making it easier for your heart to pump blood around the body and help increase the supply of blood and oxygen to your heart. Calcium channel blockers do not change the amount of calcium in your blood or bones.
Ask your doctor if you have any questions about why Norvapine has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.
Use in Children
There is not enough information to recommend the use of this medicine in children.

How to take Norvapine
Take Norvapine exactly as your doctor has prescribed.
Follow all directions given to you by your doctor or pharmacist carefully. They 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 much to take
The usual dose of Norvapine is one 5 mg tablet each day. Your doctor may increase this to one 10 mg tablet each day.
Your doctor may prescribe another dose of Norvapine depending on your condition and how you respond to this medicine.
How to take it
Swallow the tablet whole with a full glass of water.
When to take it
Take your medicine at about the same time each day, either morning or evening. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
Norvapine can be taken with or without food.
How long to take it
You must take Norvapine every day. Continue taking your medicine for as long as your doctor tells you. This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.
If you forget to take it
If it is less than 12 hours before 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.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre - the telephone number in Australia is 131 126 and in New Zealand is 0800 POISON or 0800 764 766 - 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 Norvapine.
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 may feel dizzy, lightheaded or faint and have an irregular heartbeat.
While you are taking Norvapine
Things you must do
Tell any other doctors, dentists and pharmacists who are treating you that you are taking Norvapine.
If you are about to start any new medicine, tell your doctor or pharmacist that you are taking Norvapine.
If you become pregnant while taking Norvapine, tell your doctor immediately.
Keep all of your doctor's appointments so that your progress can be checked. Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.
Things you must not do
Do not take Norvapine to treat any other conditions unless your doctor tells you to.
Do not give this medicine to anyone else, even if they have the same condition as you.
Things to be careful of
Avoid eating large quantities of grapefruit or drinking large quantities of grapefruit juice. Grapefruit juice contains one or more components that alter the metabolism of some medicines, including Norvapine.
Drinking very large quantities (over 1.2 litres) of grapefruit juice each day while taking Norvapine may increase the effects of this medicine.
Be careful driving or operating machinery until you know how Norvapine affects you. Norvapine may cause dizziness or drowsiness in some people.
If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
Things that would be helpful for your high blood pressure or angina.

Norvapine helps most people but it may have some 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 attention if you get some of the side effects.
It can be difficult to tell whether side effects are the result of taking Norvapine, effects of your condition or side effects of other medicines you may be taking. For this reason it is important to tell your doctor of any change in your condition.
Do not be alarmed by the list of possible side effects. You may not experience any of them.

If you are 65 years or older, you should be especially careful while taking Norvapine. Report any side effects promptly to your doctor. Some people in this age group may be more likely to experience side effects such as swelling of the feet and ankles, muscle cramps and dizziness.
Tell your doctor or pharmacist if you notice anything else that is making you feel unwell. Other side effects not listed above may also occur in some people.
