Zuclopenthixol Tablets: When initiating treatment with Zuclopenthixol tablets, it is recommended that the drug be given in divided doses (BID or TID). During the maintenance phase of treatment Zuclopenthixol tablets may be given as a single nighttime dose. For acute psychosis, the usual starting dose is 10-50 mg/day, which may be increased by 10-20 mg every 2-3 days, according to the patient’s response. The usual therapeutic range is 20 mg to 60 mg daily. However, as with other antipsychotic drugs, some patients may require lower, while others may require higher dosage in order to obtain optimal benefit. Daily dosage higher than 100 mg is not recommended. For maintenance therapy, dosage should be reduced to the lowest level compatible with symptom control. The usual maintenance dose is 20-40 mg/day.

Zuclopenthixol Acuphase: Dosage should be individually adjusted according to the patient’s condition. The usual dose is 50-150 mg (1-3 ml) administered intramuscularly and repeated if necessary, at intervals of 2-3 days. Some patients may need an additional injection 1 or 2 days after the first injection.

Zuclopenthixol Depot: Close supervision is required during the period following initiation of Zuclopenthixol Depot treatment, in order to minimize the risk of over-medication or insufficient suppression of psychotic symptoms. Supplemental oral antipsychotic medication may be required in diminishing dosage during this period. The usual maintenance dose is 150-300 mg intramuscularly, every 2-4 weeks. Some patients may require higher or lower doses, or shorter intervals between doses.
