What Zanidip is used for

The name of your medicine is Zanidip, which is also known as lercanidipine. Zanidip belongs to a group of medicines called calcium channel blockers (of the dihydropyridine group).
Zanidip lowers 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. Zanidip helps lower your blood pressure.
Zanidip cannot be obtained without a doctor’s prescription.
There is no evidence that Zanidip is addictive.

How to take Zanidip

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 10 mg tablet taken once daily but may be increased to 20 mg once daily.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

How to take it

Swallow Zanidip whole with a glass of water.

When to take it

Take Zanidip at about the same time each day, at least 15 minutes before a meal.
Zanidip 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

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

If you forget to take it

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 that 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 (overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26 or New Zealand 0800 764766) or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much Zanidip. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention. Keep telephone numbers of these places/services handy.
If you take too much Zanidip it may cause your blood pressure to become too low, you may become dizzy, you may get a headache and you may feel your heart beats become irregular and faster. It may also lead to unconsciousness.

While you are using Zanidip

Things you must do

Use Zanidip 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.
If you become pregnant while you are taking Zanidip, tell your doctor.
If you are about to start taking any new medicine, tell your doctor and pharmacist that you are taking Zanidip.
Tell all other doctors, dentists and pharmacists who are treating you that you are taking Zanidip.
If you have an operation, tell the anaesthetist that you are taking this medicine.

Things you must not do

Do not give Zanidip to anyone else, even if they have the same condition as you.
Do not use Zanidip to treat any other complaints unless your doctor tells you to.
Do not take Zanidip with grapefruit or grapefruit juice as these may increase the effects of this medicine.

Things to be careful of

Be careful driving or operating machinery until you know how Zanidip affects you.
Zanidip 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 Zanidip or when starting to take a different amount of medicine. Your doctor may also ask you to limit or stop your alcohol intake while taking medicines to control your blood pressure, such as Zanidip, as alcohol may increase these effects.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.

Side Effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Zanidip.
Zanidip 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.
Possible side effects include:
swelling of the ankles, feet or lower legs
dizziness or fainting
gastrointestinal disturbances such as heartburn, nausea, epigastric pain or diarrhoea
fatigue or sleepiness
These effects when they occur are usually mild. However, should you experience any of these or other undesirable effects not mentioned above, you should consult your doctor or pharmacist.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor immediately or go to Accident & Emergency at your nearest hospital if you notice any of the following:
angina (chest pain or tightness)
increased heartbeat
signs of allergy such as rash, itching or hives on the skin
These side effects are usually rare but may be serious and need urgent medical attention.
Do not be alarmed by this list of possible side effects. You may not experience any of them.

After using Zanidip


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.
Keep it in a cool dry place away from sunlight where the temperature stays below 30°C. Do not store it or any other medicine in the bathroom or near a sink.
Do not leave it in the car or on window sills.
Heat and dampness can destroy some medicines.
Keep it where children cannot reach it.
A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.


If your doctor tells you to stop taking the tablets or the tablets have passed their expiry date, ask your pharmacist what to do with any tablets that are left over.
