What Zeldox is used for

What Zeldox is for

Zeldox is used to treat schizophrenia and bipolar disorder.

Your doctor may have prescribed Zeldox for another reason.

Ask your doctor or pharmacist if you have any questions about Zeldox or why Zeldox has been prescribed for you.

Schizophrenia
Schizophrenia is a mental illness. It varies from person to person, but can involve:

  • hallucinations: the person sees, hears, feels, smells or tastes something that is not actually there; most commonly a person may hear voices
  • delusions: a delusion is a false belief held by a person which is not held by others of the same cultural background
  • disturbed or disorganised thinking
  • poor memory and concentration
  • loss of emotion and expression
  • loss of motivation and energy
  • difficulty interacting with others, leading to social isolation.

Bipolar disorder
Bipolar disorder is a mental illness where a person cycles through:

  • 'manic' phases - with symptoms such as over-activity, irritability/elation and limited need for sleep
  • 'depressive' phases - with symptoms such as depressed mood, anxiety, difficulty making decisions, concentrating and hopelessness.

How Zeldox works

Zeldox belongs to a group of medicines called atypical antipsychotics/neuroleptics. It contains the ingredient ziprasidone.

Schizophrenia
Researchers do not know exactly what causes schizophrenia, but they do know that many people with it have high levels of some brain chemicals - including dopamine and serotonin.

Zeldox is thought to work by helping to correct the imbalance of these chemicals, in turn, reducing the symptoms of schizophrenia. Research has found Zeldox can help reduce:

  • hallucinations
  • delusions
  • confused thoughts
  • social withdrawal
  • lack of motivation.

Zeldox does not cure schizophrenia, but it can help manage the symptoms and help prevent further episodes.

Taking antipsychotic/neuroleptic medicines like Zeldox can also allow you to try psychological therapies when recommended by your doctor. These may further help you manage your schizophrenia.

Bipolar disorder
Research has shown that there is a chemical imbalance in the brain in patients with bipolar disorder.

Zeldox does not cure bipolar disorder. It is used as a short-term treatment for the manic phases. Zeldox is not used to treat the depressive phases of bipolar disorder.

Controlling the manic phase of bipolar disorder with medicine can also allow you to try psychological therapies when recommended by your doctor.

Taking Zeldox

Zeldox is available only with a doctor's prescription.

Zeldox is not recommended for the treatment of elderly patients with dementia-related psychosis.

Zeldox should be used with caution in elderly patients with risk factors for stroke.

Zeldox is also not recommended for children under 18 years of age as there is not enough information on the effects of Zeldox in this group.

  • ziprasidone
  • any of the ingredients listed at the end of this leaflet.

Symptoms of an allergic reaction to Zeldox may include:

Do not take Zeldox if you have or have had any of the following medical conditions:

  • a recent heart attack

Tell your doctor or pharmacist if you are taking any other medicines, including:

  • all prescription medicines
  • all medicines you buy over the counter from a pharmacy or supermarket

How to take Zeldox

Follow all directions given to you by your doctor and pharmacist carefully. These may differ from the information contained in this leaflet.

If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.

How much to take

How much Zeldox you need to take will depend upon your condition.

Schizophrenia
The usual starting dose is one 40mg capsule taken twice daily with food.

Your doctor may increase your dose up to a maximum of one 80mg capsule twice daily with food.

Allow at least 48 hours between changes to your dose unless otherwise instructed by your doctor. You may reach the maximum dose of one 80mg capsule twice daily with food on the third day from the start of your treatment.

Bipolar disorder
The usual starting dose is one 40mg capsule twice daily with food.

Your doctor may adjust your dose up to a maximum of one 80mg capsule twice daily with food. This dose may be reached on the second day from the start of your treatment.

When to take it

Swallow the capsules whole with a full glass of water.

Take your capsule(s) with food, so in the morning with breakfast and in the evening with your evening meal. You need to take Zeldox with food because it helps your body absorb the medicine much better. If you do not take with food, the medicine may have less effect.

How long to take it

Keep taking Zeldox for as long as your doctor recommends, even if you feel better. If you keep taking Zeldox as recommended, there is less chance of your symptoms returning.

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 it as you would normally.

If you are not sure whether to skip the dose, talk to your doctor or pharmacist.

Do not double a dose to make up for the dose you have missed. This may increase the chance of you getting an unwanted side effect.

If you find it hard to remember how to take the capsules, ask your doctor or pharmacist for help.

If you take too much (overdose)

If you take too much Zeldox, you may feel slightly drowsy and show signs of tremor and uncontrollable movements of the tongue, jaw, arms and legs.

Immediately telephone your doctor or contact the Poisons Information Centre for advice by calling 13 11 26 if you are in Australia or 0800 764 766 (0800 POISON) if you are in New Zealand, or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much Zeldox. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

While you are taking it

Things you must do

Tell your doctor or pharmacist immediately if you become pregnant while taking Zeldox.

If you are about to start taking any new medicines, tell your doctor and pharmacist that you are taking Zeldox.

Tell any other doctors, dentists and pharmacist who are treating you that you are taking Zeldox.

Keep all of your doctor's appointments so that your doctor can check your progress. Your doctor will check your progress and may want to take some blood tests from time to time. This helps to prevent unwanted side effects.

Talk to your doctor or mental health professional if you have thoughts or talk about death, suicide or self-harm. These may be signs of changes or worsening in your mental illness.

Things you must not do

Do not stop taking Zeldox or change the dosage, even if you feel better, without checking with your doctor.

Do not use Zeldox to treat any other complaint unless your doctor tells you to.

Do not give Zeldox to anyone else, even if they have the same condition as you.

Things to be careful of

If you feel drowsy or sleepy while taking Zeldox, do not drive or operate machinery, or do things that could be dangerous if you are not alert. Medicines like Zeldox may cause drowsiness and sleepiness in some people. Make sure you know how you react to Zeldox before you drive a car, operate machinery or do anything else that could be dangerous if you are not alert.

Be careful when drinking alcohol while taking Zeldox. Combining Zeldox and alcohol can make you more sleepy, dizzy or light-headed. Your doctor may suggest you avoid alcohol while you are being treated with Zeldox.
