1. Why am I taking ZAN-EXTRA?

ZAN-EXTRA contains the active ingredients lercanidipine hydrochloride and enalapril maleate. ZAN-EXTRA is a combination of the two medicines. Lercanidipine belongs to a group of medicines called calcium channel blockers, enalapril belongs to a group called Angiotensin Converting Enzyme (ACE) inhibitors.

ZAN-EXTRA is used to lower high blood pressure, which doctors call hypertension. It works by relaxing some of the blood vessels in the body and reducing resistance to the flow of blood through the blood vessels.


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.

ZAN-EXTRA helps to lower your blood pressure.

2. What should I know before I take ZAN-EXTRA?


Do not take ZAN-EXTRA if:

  • you are allergic to lercanidipine, ZANIDIP®, enalapril, RENITEC®, or any other brands containing enalapril maleate, or any of the ingredients listed at the end of this leaflet. Always check the ingredients to make sure you can take this medicine.
  • you are allergic to any medicines closely related to lercanidipine (such as amlodipine, felodipine or nifedipine) or other ACE inhibitors.

Tell your doctor immediately if you become pregnant while you are taking Zan-Extra.

Check with your doctor if intend to become pregnant.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

Your baby may absorb this medicine in the womb or from breast milk and therefore there is a possibility of harm to the baby.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and ZAN-EXTRA may interfere with each other and affect how they work. These include:

  • any anti-diabetic medicine including insulin or vildagliptin (used to lower blood glucose).
    You should be closely monitored for low blood glucose levels, especially during the first month of treatment with ZAN-EXTRA.
  • arthritis medicines including gold therapy
  • carbamazepine, phenytoin
  • ciclosporin
  • cimetidine (more than 800 mg daily)
  • diuretic tablets (also called fluid or water tablets)
  • erythromycin
  • fluoxetine
  • itraconazole, ketoconazole
  • lithium, a medicine used to treat mood swings and some types of depression
  • metoprolol, propranolol
  • non-steroidal anti-inflammatory medicines, used to relieve pain, swelling and other symptoms of inflammation.
  • other blood pressure medications
  • potassium-containing salt substitutes and potassium tablets
  • rifampicin
  • ritonavir

These medicines may be affected by ZAN-EXTRA 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 can tell you what to do if you are taking any of these medicines.

Also, ask your doctor or pharmacist what to do if you are taking or are about to take the following medicines: amiodarone, digoxin, quinidine or simvastatin.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect ZAN-EXTRA.

4. How do I take ZAN-EXTRA?

How much to take

  • Follow all directions given to you by your doctor carefully.
  • These directions may differ from the information contained in this leaflet.
  • The usual dose is one tablet taken once daily.
  • If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

When to take ZAN-EXTRA

  • Take ZAN-EXTRA at about the same time each day, at least 15 minutes before a meal. Swallow ZAN-EXTRA whole with a glass of water.
  • ZAN-EXTRA will have the best effect if it is taken at the same time each day at least 15 minutes before meals. This will also help you remember when to take the tablets.

How long to take it

ZAN-EXTRA helps control your condition, but does not cure it. Therefore you must take ZAN-EXTRA every day. Continue taking the tablets for as long as your doctor tells you to.

If you forget to take ZAN-EXTRA

If you forget to take a dose but remember within 12 hours from when the dose was due, take it straight away, then continue as normal the next day. Otherwise skip that day’s dose but be sure to take the next day’s dose when it is due.

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

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

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

If you have missed several doses, consult your doctor.

If you take too much ZAN-EXTRA

If you think that you have taken too much ZAN-EXTRA, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    (Australia telephone 13 11 26) for advice, or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

If you take too much ZAN-EXTRA, it may cause your blood pressure to become too low and you may feel your heart beats become irregular and faster. It may also lead to unconsciousness.

5. What should I know while taking ZAN-EXTRA?

Things you should do

Take ZAN-EXTRA exactly as your doctor has prescribed.

If you do not follow your doctor’s instructions correctly, your blood pressure may not be controlled.

Be sure to keep all of your doctor’s appointments so that your progress can be checked.

Tell your doctor if you:

  • become pregnant while you are taking ZAN-EXTRA
  • are about to start taking any new medicine that you are taking ZAN-EXTRA

Remind any doctor, dentist or pharmacist you visit that you are taking ZAN-EXTRA.

If you have an operation, tell the anaesthetist that you are taking this medicine.

Things you should not do

  • Do not give ZAN-EXTRA to anyone else, even if they have the same condition as you.
  • Do not use ZAN-EXTRA to treat any other complaints unless your doctor tells you to.

Things to be careful of

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

As with some medicines used to treat high blood pressure such as ZAN-EXTRA, you should avoid drinking grapefruit juice.

Grapefruit juice may increase the effects of these medicines.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how ZAN-EXTRA affects you.

ZAN-EXTRA generally does not cause any problems with your ability to drive a car or operate machinery. However, as with other medicines used to treat high blood pressure, a few people may feel dizzy, light-headed or faint, especially when first taking ZAN-EXTRA or when starting to take a different amount of medicine.

Drinking alcohol

Tell your doctor if you drink alcohol.

Your doctor may also ask you to limit or stop your alcohol intake while taking medicines to control your blood pressure, such as ZAN-EXTRA, as alcohol may increase the effects of medicines used to treat high blood pressure.

Looking after your medicine

  • Keep your tablets in the blister pack until it is time to take them.
  • If you take the tablets out of the blister pack, they may not keep well.

Follow the instructions in the carton on how to take care of your medicine properly.

Store it in a cool dry place below 25°C away from moisture, heat or sunlight.

Do not store it:

  • in the bathroom or near a sink, or
  • in the car or on window sills.

Keep it where young children cannot reach it.

A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Getting rid of any unwanted medicine

If your doctor tells you to stop taking this medicine or it is out of date, take it to any pharmacy for safe disposal.

Do not use this medicine after the expiry date.
