It is recommended that initiation of treatment and dosage increases should be carried out under close supervision. As with all antipsychotic drugs, dosage should be titrated according to the needs of each patient.
Initial dosage may need to be reduced to a quarter or half the normal starting dose.
Additional Dosage Information
When transferring patients from oral to depot antipsychotic therapy, the oral medication should not be discontinued immediately, but gradually withdrawn over a period of several days after administering the first injection.

An increased risk of cerebrovascular events was identified in clinical trials when elderly patients with dementia were treated with certain antipsychotics. Increased risk with other antipsychotics or other patient populations cannot be excluded. Use with caution in patients with risk factors for stroke.
Depression is associated with an increased risk of suicidal thoughts, self harm and suicide (suicide related events). This risk persists until significant remission occurs. As improvement may not occur during the first few weeks or more of treatment, patients should be closely monitored until such improvement occurs. It is general clinical experience that the risk of self harm is highest shortly after presentation and the risk of suicide may increase again in the early stages of recovery. Furthermore, there is evidence that in children and adolescents, antidepressants may increase the risk of suicidal thoughts and self harm.
Other psychiatric conditions for which flupentixol is prescribed can also be associated with an increased risk of suicide-related events. In addition, these conditions may be co-morbid with major depressive disorder. The same precautions should observed when treating patients with major depressive disorder should therefore be observed when treating patients with other psychiatric disorders.
Patients with a history of suicide related events, those exhibiting a significant degree of suicidal ideation prior to commencement of treatment, and young adults, are at a greater risk of suicidal thought or suicide attempt, and should receive careful monitoring during treatment.
Patients (and caregivers of patients) should be alerted about the need to monitor for the emergence of suicidal thoughts and behaviour, and to seek medical advice immediately if these symptoms present.
Perform blood counts if the patient develops signs of persistent infection. Blood dyscrasias have been reported rarely.
If clinical significant hyperprolactinaemia, galactorrhoea, amenorrhoea or sexual dysfunctions occur, a dose reduction (if possible) or discontinuation should be considered.
Pregnancy and Lactation
Flupentixol should be used with caution in pregnancy.
Data describing the use of flupentixol in pregnancy is highly limited. Flupentixol crosses the placental barrier. The manufacturer suggests avoid the use of flupentixol during pregnancy, particularly during the first and last trimesters. Postulated risks to the newborn include lethargy, tremor, hyperexcitability and low apgar scores.
When neuroleptics have been used up to delivery, observation of the neonate for at least 2 days is recommended. In order to prevent neonatal adaptation disorders, prescribers are advised to reduce the dose or even interrupt treatment in the days immediately preceding delivery (Schaefer 2007).
The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame.

Flupentixol is contraindicated in breastfeeding.
Flupentixol is excreted into breast milk. Although the effects of long-term exposure have not been studied it has been suggested that extended exposure to flupentixol may affect the nursing infant's neurobehavioral mechanisms. Currently no adverse effects have been reported in breast-feeding infants whose mothers were receiving flupentixol.
LactMed suggests that if flupentixol is used during breastfeeding careful monitoring of the infant should be conducted.
Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
