Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Zypine; Zypine ODT.

What is in this leaflet

This leaflet answers some common questions about ZYPINE and ZYPINE ODT (orally disintegrating tablets).

It does not contain all the available information. It does not take the place of talking with your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking ZYPINE against the benefits expected for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What ZYPINE is used for

ZYPINE is used to treat:

  • Symptoms of schizophrenia and related psychoses
  • Acute manic episodes associated with Bipolar I Disorder (as a short-term treatment) with ZYPINE alone or in combination with lithium or valproate.
  • Mood stabiliser that prevents further occurrences of the disabling high and low (depressed) extremes of mood associated with Bipolar I Disorder

ZYPINE belongs to a group of medicines called antipsychotics.

This medicine helps by correcting chemical imbalances in the brain, which may cause mental illness.

Schizophrenia is a mental illness with disturbances in thinking, feelings and behaviour.

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.

ZYPINE may be used alone, or in combination with other medicines, to treat your condition.

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.

There is not enough information to recommend the use of this medicine for children under the age of 18 years.

This medicine is available only with a doctor's prescription.

Before you take ZYPINE

When you must not take it

Do not take ZYPINE if you have an allergy to:

  • any medicine containing olanzapine
  • any of the ingredients listed at the end of this leaflet.
  • any other similar medicines (such as medicines of the same class or with a similar structure, as per PI).

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • rash, itching or hives on the skin

Do not take this medicine if you are pregnant. It may affect your developing baby if you take it during pregnancy.

Do not breast-feed if you are taking this medicine. The active ingredient in Olanzapine passes into breast milk (if applicable) and there is a possibility that your baby may be affected.

Do not give this medicine to a child under the age of 18 years. Safety and effectiveness in children younger than 18 years have not been established.

Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If you take this medicine after the expiry date has passed it may not work as well.

If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should start taking this medicine, talk to your doctor or pharmacist.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor if you have or have had any of the following medical conditions:

  • tumour of the pituitary gland (a small gland at the base of the brain)
  • disease of the blood or bone marrow with a reduced number of white or red blood cells
  • disease of the blood vessels of the brain, including stroke
  • prostate problems
  • kidney or liver disease
  • high blood sugar, diabetes or a family history of diabetes
  • breast cancer or a family history of breast cancer
  • paralytic ileus, a condition where the small bowel does not work properly
  • epilepsy, seizures or fits
  • glaucoma, a condition in which there is usually a build up of fluid in the eye
  • heart disease, including irregular heart rhythm
  • neuroleptic malignant syndrome, a reaction to some medicines with a sudden increase in body temperature, extremely high blood pressure and severe convulsions
  • tardive dyskinesia, a reaction to some medicines with uncontrollable twitching or jerking movements of the arms and legs.
  • sleep apnoea, a sleep disorder where a person has pauses in breathing or periods of shallow breathing during sleep.

Tell your doctor if you are pregnant or plan to become pregnant. Like most antipsychotic medicines, ZYPINE is not recommended for use during pregnancy. Newborn babies of mothers taking antipsychotic drugs (including ZYPINE) during the last trimester of pregnancy are at risk of experiencing extrapyramidal neurological disturbances and/or withdrawal symptoms following delivery. These may include, but are not limited to agitation, tremor, muscle stiffness or weakness, drowsiness, feeding problems, and breathing difficulty. If there is a need to consider ZYPINE during pregnancy, your doctor will discuss with you the benefits and risks of using it.

Tell your doctor if you are breastfeeding or plan to breastfeed. It is recommended that you do not breastfeed while taking ZYPINE.

Tell your doctor if you suffer from lactose intolerance (because ZYPINE tablets contain lactose).

Tell your doctor if you suffer from phenylketonuria (because ZYPINE ODT contains aspartame).

Tell your doctor if you will be in a hot environment or do a lot of vigorous exercise. ZYPINE may make you sweat less, causing your body to overheat.

Tell your doctor if you smoke. Smoking may affect ZYPINE or may affect how it works.

If you are elderly with dementiarelated psychosis, tell your doctor if you have previously had a stroke or transient ischaemic attack (ministroke) or if you have high blood pressure.

If you have not told your doctor about any of the above, tell them before you start taking ZYPINE.

Taking other medicines

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

Some medicines and ZYPINE may interfere with each other. These include:

  • medicines used to treat a fast or irregular heart beat (arrhythmia)
  • medicines taken for anxiety or to help you sleep
  • medicines taken for depression
  • carbamazepine, a medicine used for mood stabilisation and to treat epilepsy
  • other centrally acting medicines (e.g. tranquillisers or strong painkillers)
  • ciprofloxacin, a medicine used to treat bacterial infections
  • medicines that lower blood pressure
  • medicines used for Parkinson's disease.
  • medicines known to change heart's electrolyte activity or make it more likely to change.

These medicines may be affected by ZYPINE or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking ZYPINE.

How to take ZYPINE

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

Your doctor will tell you how much ZYPINE 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

ZYPINE tablets should be swallowed whole with a glass of water.

ZYPINE ODT break easily, so you should handle them carefully.

Do not handle the ZYPINE ODT with wet hands as the tablets may break up.

  1. 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.
  2. Carefully peel off the backing.
  3. Gently push the tablet out.
  4. Put the tablet in your mouth. It will dissolve directly in your mouth, so that it can be easily swallowed.

You can also place the tablet 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.

The ZYPINE ODT should not be place in cola drinks.

When to take it

ZYPINE should be taken once a day as advised by your doctor.

Take your prescribed dose at the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.

ZYPINE can be taken with or without food.

How long to take it

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.

It is important that you do NOT stop taking ZYPINE 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, 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 that you or anyone else may have taken too much ZYPINE. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

If you take too much ZYPINE, the most common signs are fast heart beat, agitation/aggression, difficulty speaking, uncontrollable movements and sedation.

While you are using ZYPINE

Things you must do

It is important that you remember to take ZYPINE daily and at the dose prescribed by your doctor.

Tell all doctors, dentists and pharmacists who are treating you that you are taking ZYPINE.

While you are taking ZYPINE, tell your doctor or pharmacist before you start any new medicine.

If you become pregnant while taking ZYPINE, tell your doctor.

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine. It may affect other medicines used during surgery.

If you are about to have any blood tests, tell your doctor that you are taking this medicine. It may interfere with the results of some tests.

Keep all of your doctor's appointments so that your progress can be checked.

Your doctor should monitor your weight while you are taking ZYPINE.

Patients with diabetes or who have a higher change of developing diabetes should have their blood sugar checked often.

Your doctor may request you have a blood test from time to time to monitor your cholesterol levels.

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 your medicine or change the dosage, even if you are feeling better, without checking with your doctor.

Do not give your medicine to anyone else, even if they have the same condition as you. Your doctor has prescribed ZYPINE for you and your condition.

Things to be careful of

Be careful driving or operating machinery until you know how ZYPINE affects you. ZYPINE may cause drowsiness in some people.

Be careful when drinking alcohol while you are taking ZYPINE. The effects of alcohol could be made worse while taking ZYPINE.

Your doctor may suggest you avoid alcohol while you are being treated with ZYPINE.

If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.

If outdoors, wear protective clothing and use at least a 30+ sunscreen. ZYPINE 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. ZYPINE may affect the way your body reacts to temperature changes. Antipsychotics have the potential to cause cardiac complications and sudden cardiac death.

4 Clinical Particulars

4.9 Overdose

Symptoms. Signs of oral toxicity in rodents were characteristic of potent neuroleptic compounds: hypoactivity, coma, tremors, clonic convulsions and salivation. In dogs, olanzapine caused sedation, ataxia, tremors, tachycardia, laboured respiration, miosis and anorexia. In monkeys, prostration and semiconsciousness were observed.
Signs and symptoms. Very common symptoms (≥ 10% incidence) reported in olanzapine overdose include tachycardia, agitation/ aggressiveness, dysarthria, various extrapyramidal symptoms and reduced level of consciousness ranging from sedation to coma.
Other medically significant sequelae of olanzapine overdose include delirium, convulsion, possible neuroleptic malignant syndrome, respiratory depression, aspiration, hypertension or hypotension, cardiac arrhythmias (< 2% of overdose cases) and cardiopulmonary arrest. Fatal outcomes have been reported for acute overdoses as low as 450 mg but survival has also been reported following acute overdose of 2 g.
Treatment. There is no specific antidote to olanzapine. Induction of emesis is not recommended. Standard procedures for management of overdose may be indicated. The possibility of multiple drug involvement should be considered.
In case of acute overdosage, establish and maintain an airway and ensure adequate oxygenation and ventilation. The use of activated charcoal for overdose should be considered because the concomitant administration of activated charcoal was shown to reduce the oral bioavailability of olanzapine by 50% to 60%. In patients who are not fully conscious or who have impaired gag reflex, consideration should be given to administering activated charcoal via a nasogastric tube, once the airway is protected. Olanzapine is not substantially removed by haemodialysis.
Symptomatic treatment and monitoring of vital organ function should be instituted according to clinical presentation, including treatment of hypotension and circulatory collapse and support of respiratory function. Hypotension and circulatory collapse should be treated with appropriate measures such as intravenous fluids and/or sympathomimetic agents such as noradrenaline (norepinephrine). Adrenaline (epinephrine), dopamine or other sympathomimetic agents should not be used since beta-stimulation may worsen hypotension in the setting of alpha-blockade induced by olanzapine. Cardiovascular monitoring should be considered to detect possible arrhythmias. Close medical supervision and monitoring should continue until the patient recovers.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.3 Preclinical Safety Data

Genotoxicity. Olanzapine was not mutagenic or clastogenic in a full range of standard tests, which included bacterial mutation tests and in vitro and in vivo tests, indicating that it is not a genotoxic carcinogen.
Carcinogenicity. Carcinogenicity studies in mice and rats showed the development of mammary adenocarcinomas at oral doses greater than 0.5 and 1 mg/kg/day respectively.
The increased incidence of mammary tumours may be due to an endocrine mechanism, possibly involving elevation of circulating prolactin levels in response to the dopamine D2-receptor antagonistic activity of olanzapine. Mammary tumours are known to occur in rats and mice treated with other drugs that antagonise dopamine D2-receptors. Neither clinical studies nor epidemiological studies conducted to date have shown an association between these drugs and carcinogenesis, but the available evidence is considered too limited to be conclusive at this time. The use of olanzapine in patients with a familial history or previously detected breast cancer should be avoided. Caution should also be exercised when considering olanzapine treatment in patients with pituitary tumours.
