What LANZEK is used for
LANZEK belongs to a group of medicines called antipsychotics. It helps to correct chemical imbalances in the brain, which may cause mental illness.
LANZEK is used to treat symptoms of schizophrenia and related psychoses. Schizophrenia is a mental illness with disturbances in thinking, feelings and behaviour.
LANZEK alone, or in combination with lithium or valproate, is used for the short-term treatment of acute manic episodes associated with Bipolar I Disorder. LANZEK is also a mood stabiliser that prevents further occurrences of the disabling high and low (depressed) extremes of mood associated with Bipolar I Disorder.
Bipolar I Disorder is a mental illness with symptoms such as feeling "high", having excessive amounts of energy, needing much less sleep than usual, talking very quickly with racing ideas and sometimes severe irritability.
Your doctor may have prescribed LANZEK for another reason.
Ask your doctor if you have any questions about why LANZEK has been prescribed for you. This medicine is available only with a doctor's prescription.
LANZEK is not recommended for use in children under the age of 18 years as there is not enough information on its effects in this age group.
Before taking LANZEK

Signs of an allergic reaction may include a skin rash, itching, shortness of breath or swelling of the face, lips or tongue.
- if the packaging is torn or shows signs of tampering or the tablets or wafers do not look quite right.

How to take LANZEK
Follow all directions given to you by your doctor or pharmacist carefully. These may differ from the information contained in this leaflet.
How much to take
LANZEK tablets or wafers:
Your doctor will tell you how many LANZEK tablets or wafers you should take. The dose your doctor will prescribe for you will usually be in the range 5 mg to 20 mg per day.
Your doctor may increase or decrease your dose in order to find the appropriate dose for your condition.
A lower starting dose may be prescribed for elderly patients over the age of 65 years.
How to take it
LANZEK tablets should be swallowed whole with a glass of water.
LANZEK Zydis wafers:
Do not handle the wafers with wet hands as the wafers may break up. LANZEK Zydis wafers break easily, so you should handle them carefully.
The wafers can be taken two ways:
- Directly into your mouth
- In a drink
To take a wafer directly into your mouth:
- Hold the blister strip at the edges and separate one blister cell from the rest of the strip by gently tearing along the perforations around it.
- Carefully peel off the coloured backing.
- Gently push the wafer out.
- Put the wafer in your mouth. It will dissolve directly in your mouth, so that it can be easily swallowed.
To take a wafer in a drink:
You can also place the wafer in a full glass or cup of water, orange juice, apple juice, milk or coffee, and stir.
Drink it straight away.
With some drinks, the mixture may change colour and possibly become cloudy.
Do not place the wafer in cola drinks.
When to take it
LANZEK tablets or wafers should be taken once a day as advised by your doctor. Take your prescribed dose at the same time each day.
LANZEK tablets or wafers can be taken with or without food.
How long do I take it
Do not stop taking LANZEK just because you feel better. It is important that you do NOT stop taking LANZEK unless your doctor tells you.
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 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.
If you are not sure what to do, ask your doctor or pharmacist.
If you take too much
Immediately telephone your doctor or the Australian Poisons Information Centre (telephone 13 11 26) or the New Zealand National Poisons Centre (0800 POISON or 0800 764 766), or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else has taken too much LANZEK. Do this even if there are no signs of discomfort or poisoning. If you have taken too much LANZEK, the most common signs are fast heart beat, agitation/aggression, difficulty speaking, uncontrollable movements and sedation.
While you are taking LANZEK
Things you must do
It is important that you remember to take LANZEK daily and at the dose prescribed by your doctor.
Tell all doctors, dentists and pharmacists who are treating you that you are taking LANZEK.
While you are taking LANZEK, tell your doctor or pharmacist before you start any new medicine.
If you become pregnant while taking LANZEK, tell your doctor.
Keep all of your doctor's appointments so that your progress can be checked.
- Your doctor should monitor your weight while you are taking LANZEK.
- Patients with diabetes or who have a higher chance of developing diabetes should have their blood sugar checked often.
- If you are over 65, your doctor may measure your blood pressure from time to time.
Tell your doctor if you are female and your monthly periods are absent for six months or more.
Talk to your doctor or mental health professional if you have thoughts or talk about death or suicide; or thoughts or talk about self-harm or doing harm to others. These may be signs of changes or worsening in your mental illness.
Things you must not do
Do not stop taking LANZEK, or lower the dosage, even if you are feeling better, without checking with your doctor.
Do not give LANZEK to anyone else, even if their symptoms seem similar or they have the same condition as you. Your doctor has prescribed LANZEK for you and your condition.
Things to be careful of
Be careful driving or operating machinery until you know how LANZEK affects you. LANZEK may cause drowsiness in some people.
Be careful when drinking alcohol while taking LANZEK. The effects of alcohol could be made worse while taking LANZEK.
Your doctor may suggest you avoid alcohol while you are being treated with LANZEK.
If LANZEK makes you feel light-headed, dizzy or faint, be careful when getting up from a sitting or lying position. Getting up slowly may help.
If outdoors, wear protective clothing and use at least a 30+ sunscreen. LANZEK may cause your skin to be much more sensitive to sunlight than it is normally.
Exposure to sunlight may cause a skin rash, itching, redness, or severe sunburn.
If your skin does appear to be burning, tell your doctor.
Make sure you keep cool in hot weather and keep warm in cool weather. LANZEK may affect the way your body reacts to temperature changes
