TAJ PHARMA Haloperidol has been associated with dose-dependent QT interval prolongation.
Precautions
TAJ PHARMA Haloperidol is contraindicated in severe toxic central nervous system depression or comatose states from any cause and in individuals who have Parkinson's disease.
Sudden death has been reported in psychiatric patients treated with TAJ PHARMA Haloperidol. In addition, QT interval prolongation and Torsades de Pointes have been observed in patients treated with TAJ PHARMA Haloperidol. The risk of QT interval prolongation and Torsades de Pointes appears to be increased when larger than recommended dosages are used, and with intravenous administration. Patients with conditions that prolong the QT interval (e.g., cardiac abnormalities, hypothyroidism, long QT syndromes, hypokalemia, hypomagnesemia, electrolyte imbalances, drugs known to prolong QT, etc.) should be treated with caution. TAJ PHARMA Haloperidol decanoate must never be given intravenously. TAJ PHARMA Haloperidol lactate is not approved for intravenous use; however, if intravenous administration is given, the ECG should be monitored for QT prolongation and arrhythmias.
Dialysis
A supplemental dose is not necessary with dialysis.
Other Comments
Upon achieving a satisfactory therapeutic response, dosage should then be gradually reduced to the lowest effective maintenance level.

WARNING
Increased Mortality in Elderly Patients with Dementia-Related Psychosis
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of seventeen placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group. Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. TAJ PHARMA Haloperidol Injection is not approved for the treatment of patients with dementia-related psychosis (see WARNINGS).

Renal Dose Adjustments
The manufacturer recommends caution when administering this drug to patients with renal dysfunction.
Liver Dose Adjustments
The manufacturer recommends caution when administering this drug to patients with liver dysfunction.
Dose Adjustments
TAJ PHARMA Haloperidol has been associated with dose-dependent QT interval prolongation.
Precautions
TAJ PHARMA Haloperidol is contraindicated in severe toxic central nervous system depression or comatose states from any cause and in individuals who have Parkinson's disease.
Sudden death has been reported in psychiatric patients treated with TAJ PHARMA Haloperidol. In addition, QT interval prolongation and Torsades de Pointes have been observed in patients treated with TAJ PHARMA Haloperidol. The risk of QT interval prolongation and Torsades de Pointes appears to be increased when larger than recommended dosages are used, and with intravenous administration. Patients with conditions that prolong the QT interval (e.g., cardiac abnormalities, hypothyroidism, long QT syndromes, hypokalemia, hypomagnesemia, electrolyte imbalances, drugs known to prolong QT, etc.) should be treated with caution. TAJ PHARMA Haloperidol decanoate must never be given intravenously. TAJ PHARMA Haloperidol lactate is not approved for intravenous use; however, if intravenous administration is given, the ECG should be monitored for QT prolongation and arrhythmias.
Dialysis
A supplemental dose is not necessary with dialysis.
Other Comments
Upon achieving a satisfactory therapeutic response, dosage should then be gradually reduced to the lowest effective maintenance level.

WARNING
Increased Mortality in Elderly Patients with Dementia-Related Psychosis
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of seventeen placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group. Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. TAJ PHARMA Haloperidol Injection is not approved for the treatment of patients with dementia-related psychosis (see WARNINGS).
TAJ PHARMA Haloperidol Description
TAJ PHARMA Haloperidol is the first of the butyrophenone series of major antipsychotics. The chemical designation is 4-[4-(p-chlorophenyl)-4-hydroxypiperidino]-4'-fluorobutyrophenone and it has the following structural formula:
TAJ PHARMA Haloperidol is available as a sterile parenteral form for intramuscular injection. The injection provides 5 mg TAJ PHARMA Haloperidol (as the lactate) and lactic acid for pH adjustment between 3.0 – 3.6.
ACTIONS
The precise mechanism of action has not been clearly established.
