Key Facts: It will take around four to six weeks for a patient to feel the full benefits of Pericyazine. However, anxiety should lessen rapidly upon consumption of the drug. There are some side effects to Pericyazine, as mentioned below. Pericyazine should be used without interruption – you shouldn’t suddenly stop taking the medicine. The medicine should help control your symptoms.


How do they work?: Antipsychotics cannot help cure mental health conditions, but they are usually effective in reducing and controlling some of the symptoms associated with these conditions. These symptoms can include delusions and hallucinations, disturbed thoughts, agitation, mania and violence. The medication works by blocking the action of dopamine. It is believed psychotic episodes are caused by the brain producing too much of the chemical dopamine. The medication also regulates levels of other chemicals that are responsible for regulating mood – such as noradrenaline and serotonin. It is recommended that Pericyazine is used in conjunction with therapy.


Dosage: Pericyazine comes in tablet form. You are recommended to swallow the tablets with a drink of water. For Schizophrenia, the starting dose is 75mg per day. You should divide this in three equal doses – taking 25mg per day at intervals of six-eight hours. The maximum dose is 300mg per day. For Anxiety, 30mg is the starting dose, again in three doses. The dose can be increased gradually if required. You should ensure you try and limit touching the tablets, as they can cause skin redness. The typical treatment course for Pericyazine differs from patient to patient.
