1. What is Orizon and what is it used for

Orizon belongs to a group of medicines called antipsychotics.
Orizon is used to treat:

• schizophrenia - a condition where you may see, hear, or feel things that are not there, believe things that are not true, or feel unusually suspicious or confused
• manic episodes - a condition where you may feel very excited, elated, agitated, or hyperactive. Manic episodes occur in bipolar disorder
• short-term treatment (up to 6 weeks) of persistent aggression in patients with Alzheimer's dementia who are harming themselves or others. Before taking the medicine, non-pharmacological treatment methods should be used
• short-term treatment (up to 6 weeks) of persistent aggression in mentally retarded children (over 5 years) and adolescents with behavioral disorders

Orizon may help alleviate symptoms of the disease and prevent the recurrence of symptoms.

2. Before you take Orizon

When not to take Orizon

• if you are allergic to risperidone or any of the other ingredients of this medicine (listed in section 6).

If you are not sure if the above applies to you, talk to your doctor or pharmacist before taking Orizon.

Warnings and precautions

Before starting treatment with Orizon, discuss with your doctor or pharmacist if:

• you have heart problems, such as an irregular heartbeat or a tendency to low blood pressure, or if you are taking blood pressure-lowering medicines. Orizon may cause a decrease in blood pressure. It may be necessary to adjust the dose of the medicine.
• you know of any factors that may predispose you to stroke, such as high blood pressure, cardiovascular disease, or cerebral vascular disorders
• you have ever had involuntary rhythmic movements of the tongue, lips, or face
• you have ever had a condition characterized by fever, stiff muscles, sweating, or decreased consciousness (also known as neuroleptic malignant syndrome)
• you have Parkinson's disease or dementia
• you have had a low white blood cell count in the past (which may or may not have been caused by other medicines)
• you have diabetes
• you have epilepsy
• you are a man and have had a prolonged or painful erection
• you have problems with body temperature regulation or are overheating
• you have kidney problems
• you have liver problems
• you have been found to have a high level of the hormone prolactin in your blood or have a prolactin-dependent tumor
• you or a family member have had blood clots in the past, as antipsychotic medicines have been associated with the formation of blood clots.

If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before taking Orizon.
Your doctor may order a white blood cell count test, as very rarely, patients taking antipsychotic medicines have had a dangerously low white blood cell count.
Orizon may cause weight gain. Significant weight gain can affect your health. Your doctor will regularly check your weight.
Your doctor should check if you have symptoms of high blood sugar, as diabetes has been reported in patients taking Orizon, and worsening of existing diabetes has been observed in patients with diabetes.
For patients with existing diabetes, blood sugar levels should be regularly monitored.
Orizon often increases the level of a hormone called "prolactin". This can cause side effects such as menstrual disorders, fertility problems in women, breast enlargement in men (see "Possible side effects"). If such side effects occur, it is recommended to have a blood test for prolactin levels.
During cataract surgery, the pupil of the eye of a patient taking risperidone may not dilate sufficiently. The iris of the eye may also become floppy during the procedure, which can result in eye damage. If you are scheduled for eye surgery, tell your eye doctor about taking this medicine.

Elderly patients with dementia

In elderly patients with dementia, there is an increased risk of stroke. Patients with dementia caused by stroke should not take risperidone.
During treatment with Orizon, the patient should frequently consult with the doctor.
Seek medical help immediately if the patient or caregiver notices a sudden change in the patient's mental state or sudden weakness or numbness of the face, arms, or legs, especially if it occurs on one side, or speech disorders, even if they only last for a short time. These symptoms may indicate a stroke.

Children and adolescents

Before starting treatment for behavioral disorders, other causes of aggressive behavior should be ruled out. If the patient experiences fatigue, concentration problems during treatment, changing the time of risperidone administration may improve it.
Before starting treatment, the patient, both adult and child, should be weighed, and then regularly monitored for weight during treatment.
In a small study, an increase in growth was observed in children taking risperidone, but it is not known if this is due to the effect of the medicine or other factors.

Orizon and other medicines

Tell your doctor or pharmacist about all medicines you are taking now or have recently taken, as well as any medicines you plan to take.
Patients should especially inform their doctor or pharmacist if they are taking any of the following medicines:

• medicines that act on the brain, such as sedatives (benzodiazepines) or certain painkillers (opioids), antihistamines, as risperidone may enhance their sedative effect
• medicines that can change the electrical activity of the heart, such as malaria medicines, anti-arrhythmic medicines, antihistamines, or certain antidepressants
• medicines that slow down the heart rate
• medicines that lower potassium levels in the blood (e.g., certain diuretics)
• medicines used to treat high blood pressure. Orizon may lower blood pressure
• medicines used to treat Parkinson's disease, such as levodopa
• medicines that increase the activity of the central nervous system (psychostimulants, such as methylphenidate)
• diuretics (used in heart disease or to relieve swelling in areas where there is excessive fluid accumulation, such as furosemide or chlorothiazide). Orizon taken alone or with furosemide may increase the risk of stroke or death in elderly patients with dementia.

The following medicines may weaken the effect of risperidone:

• rifampicin (a medicine used to treat certain infections)
• carbamazepine, phenytoin (medicines for epilepsy)
• phenobarbital. If you start or stop taking these medicines, it may be necessary to change the dose of risperidone.

The following medicines may enhance the effect of risperidone:

• quinidine (used in certain heart diseases)
• antidepressants, such as paroxetine, fluoxetine, tricyclic antidepressants
• beta-adrenergic blockers (used to treat high blood pressure)
• phenothiazines (used to treat psychosis or to sedate)
• cimetidine, ranitidine (reducing stomach acid)
• itraconazole or ketoconazole (used in fungal infections)
• certain medicines used to treat HIV/AIDS, such as ritonavir
• verapamil, used to treat high blood pressure and/or arrhythmias
• sertraline and fluvoxamine, used to treat depression and other mental disorders. If you start or stop taking these medicines, it may be necessary to change the dose of risperidone.

If you are not sure if any of the above situations apply to you, talk to your doctor or pharmacist before taking Orizon.
