CLOZAPINE
About
CLOZAPINE is used to treat schizophrenia. Additionally, CLOZAPINE is also used to reduce the risk of suicidal behaviour in patients with schizophrenia or other similar disorders. Schizophrenia is a medical condition in which the person may feel, hear or see things that are not there, believe things that are not true, or feel unusually suspicious or confused.
CLOZAPINE contains ‘Clozapine’, which works by blocking the effects of chemical receptors in the brain, such as dopamine and serotonin. Thus, it helps in improving mood, behaviour and thoughts.
You are advised to take CLOZAPINE for as long as your doctor has prescribed it for you, depending on your medical condition. In some cases, CLOZAPINE may cause side effects such as tachycardia (fast heartbeat), dizziness, headache, tremor, sweating, dry mouth, nausea, constipation and visual disturbances. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.
Please do not stop taking CLOZAPINE suddenly, as it might cause withdrawal symptoms. Consult your doctor if you are pregnant. Do not take CLOZAPINE if you are breastfeeding, as it may pass into breastmilk. Avoid driving as CLOZAPINE may cause drowsiness and dizziness. CLOZAPINE should not be given to children as safety and effectiveness have not been established. Avoid consuming alcohol with CLOZAPINE as it could lead to increased drowsiness and dizziness. Keep your doctor informed about your health condition and medicines to rule out any side effects.
Uses of CLOZAPINE
Medicinal Benefits
CLOZAPINE belongs to a group of medicines called antipsychotics. CLOZAPINE is used to treat schizophrenia and to reduce the risk of suicidal behaviour in patients with schizophrenia or other similar disorders. CLOZAPINE works by blocking the effects of chemical receptors in the brain, such as dopamine and serotonin, thereby helping in improving mood, behaviour and thoughts. CLOZAPINE is used to treat schizophrenia when other antipsychotic drugs are ineffective or have caused severe adverse effects. CLOZAPINE is also used to treat psychotic disorders in patients with Parkinson’s disease when standard treatments have failed.
