What PRYZEX is used for

PRYZEX belongs to a group of medicines called antipsychotics. It helps to correct chemical imbalances in the brain, which may cause mental illness.

PRYZEX is used to treat symptoms of schizophrenia and related psychoses.

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

PRYZEX alone, or in combination with lithium or valproate, is used for the short-term treatment of acute manic episodes associated with Bipolar I Disorder.

PRYZEX 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 PRYZEX for another reason.

Ask your doctor if you have any questions about why PRYZEX has been prescribed for you.

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

PRYZEX 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 PRYZEX

Tell your doctor if you have any of the following conditions or if you have ever experienced any of these conditions.

When you must not take it

Do not take PRYZEX:

  • if the packaging is torn or shows signs of tampering or the tablets do not look quite right.

How to take PRYZEX

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

PRYZEX film coated or orally dispersible tablets:
Your doctor will tell you how many PRYZEX tablets 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

These orally disintegrating tablets will dissolve in your mouth, therefore do not require water.

You can also place these tablets in a full glass 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 orally disintegrating tablets should not be placed in cola drinks.

When to take it

PRYZEX orally disintegrating tablets should be taken once a day as advised by your doctor.

Take your prescribed dose at the same time each day.

PRYZEX tablets can be taken with or without food.

How long to take it

Do not stop taking PRYZEX just because you feel better. It is important that you do NOT stop taking PRYZEX 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 (overdose)

Immediately telephone your doctor or the Australian Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else has taken too much PRYZEX. Do this even if there are no signs of discomfort or poisoning.

If you have taken too much PRYZEX, the most common signs are fast heartbeat, agitation/aggression, difficulty speaking, uncontrollable movements and sleepiness (sedation).

While you are taking PRYZEX

Things you must do

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

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

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

If you become pregnant while taking PRYZEX, 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 PRYZEX.

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

Do not give PRYZEX to anyone else, even if their symptoms seem similar or they have the same condition as you. Your doctor has prescribed PRYZEX for you and your condition.

Things to be careful of

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

Be careful drinking alcohol while taking PRYZEX. The effects of alcohol could be made worse while taking PRYZEX.

If PRYZEX makes you feel lightheaded, dizzy or faint, be careful 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. PRYZEX 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.
