What is in this leaflet
This leaflet answers some common questions about Anpec.
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have benefits and risks. Your doctor has weighed the risks of you taking Anpec against the benefits expected for you.
If you have any concerns about taking this medicine, talk to your doctor or pharmacist.
Keep this leaflet with your medicine. You may need to read it again.
What Anpec is used for
Anpec tablets are used to treat:
- high blood pressure, also called hypertension
- angina (chest pain)
- some types of arrhythmias (irregular heartbeats).
Anpec belongs to a group of medicines called calcium antagonists or calcium channel blockers. These medicines work by opening up blood vessels, causing blood pressure to fall and letting more blood and oxygen reach the heart. Calcium channel blockers also help control an irregular heartbeat.
Anpec does not change the amount of calcium in your blood or bones. Calcium in your diet or in calcium supplements will not interfere with the way Anpec works.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.

How to take Anpec
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the bottle, ask your doctor or pharmacist.
How much to take
The dose varies from person to person.
Your doctor will tell you how many tablets you need to take each day and when to take them. This depends on the condition being treated and whether or not you are taking any other medicines.
People with liver problems may need smaller doses.
How to take it
Swallow the tablets with a glass of water.
Anpec tablets can be divided in half along the breakline, if your doctor has prescribed half a tablet.
When to take it
Anpec tablets are usually taken two or three times a day, space the tablets evenly apart throughout the day.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
It does not matter if you take this medicine before or after food.
How long to take it
Anpec is usually taken as long-term treatment.
Continue taking your medicine for as long as your doctor tells you to.
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 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 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 the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much Anpec. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much Anpec, you may develop a slow heartbeat, experience chest pain, feel very faint or collapse.

Anpec may cause tiredness, dizziness or lightheadedness in some people, especially when they first start taking the medicine or the dose is changed.
Be careful drinking alcohol while taking Anpec. Combining alcohol with Anpec may make you more drowsy, dizzy or lightheaded. Your doctor may suggest you avoid alcohol while you are taking Anpec.
