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 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 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.
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:
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.
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.
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.
