Interactions

Drugs that Prolong QTc Interval: Avoid concomitant use with haloperidol decanoate injection ( 7.1 ). See full prescribing information for additional clinically significant drug interactions with haloperidol decanoate injection ( 7.2 ).

7.1 Drugs that Prolong the QTc Interval Avoid concomitant use of haloperidol decanoate injection with other drugs with a known potential to prolong the QTc interval. If concomitant use cannot be avoided [see Warnings and Precautions (5.2) ] : Obtain ECGs when initiating and during concomitant use as clinically indicated. Obtain serum electrolytes (including potassium, calcium, phosphorus, and magnesium) when initiating and during concomitant use as clinically indicated.

QTc interval prolongation has been observed with haloperidol decanoate injection treatment. Concomitant use of haloperidol decanoate injection with other products that prolong the QTc interval may result in a greater increase in the QTc interval, and adverse reactions associated with QTc interval prolongation, including torsade de pointes, other serious arrythmias, and sudden death [see Warnings and Precautions (5.2) ].

7.2Other Clinically Significant Drug Interactions Table

3 describes other clinically significant drug interactions of haloperidol decanoate injection. Table 3: Other Clinically Significant Drugs Interactions 1 CNS Depressants Clinical Impact Haloperidol may potentiate CNS depressants. Prevention or Management Avoid concomitant use of haloperidol decanoate injection with CNS depressants such as anesthetics, opioids, and alcohol. CYP3A4 and/or CYP2D6 Inhibitors Clinical Impact CYP3A4 and/or CYP2D6 inhibitors increase haloperidol exposure (haloperidol is a CYP3A4 and CYP2D6 substrate) [see Clinical Pharmacology (12.3) ].

Concomitant use of haloperidol decanoate injection and CYP3A4 and/or CYP2D6 inhibitors may increase the risk of haloperidol-associated adverse reactions. Prevention or Management Monitor for signs or symptoms of increased or prolonged pharmacologic effects of haloperidol. Decrease the dosage of haloperidol decanoate injection as clinically necessary. CYP3A4 Inducers Clinical Impact CYP3A4 inducers decrease haloperidol exposure (haloperidol is a CYP3A4 substrate) [see Clinical Pharmacology (12.3) ].

Concomitant use of haloperidol decanoate injection with CYP3A4 inducers may reduce the effectiveness of haloperidol decanoate injection. Prevention or Management Monitor patients and if necessary, increase the dosage of haloperidol decanoate injection. CYP2D6 Substrates Clinical Impact Haloperidol is a CYP2D6 inhibitor. Plasma concentrations of CYP2D6 substrates may increase when they are concomitantly administered with haloperidol decanoate injection.

Prevention or Management Monitor plasma concentrations of the CYP2D6 substrate, if possible. Consider reducing the dosage of the CYP2D6 substrate, if necessary. Refer to the Prescribing Information of the CYP2D6 substrate. Dopaminergic Drugs Clinical Impact Haloperidol may antagonize the effects of levodopa, dopamine agonists, and other drugs intended to increase dopamine levels. Prevention or Management Haloperidol decanoate injection is contraindicated in patients with Parkinson's disease and dementia with Lewy bodies.

For conditions other than Parkinson's disease and dementia with Lewy bodies, when possible, avoid concomitant use of haloperidol decanoate injection with dopaminergic drugs [see Warnings and Precautions (5.7) ] . Anticholinergic Drugs Clinical Impact The healthcare provider should keep in mind the possible increase in intraocular pressure when anticholinergic drugs are administered concomitantly with haloperidol decanoate injection.

Prevention or Management Monitor and manage patients as clinically appropriate. Lithium Clinical Impact Concomitant use of haloperidol decanoate injection with lithium may cause an encephalopathic syndrome followed by irreversible brain damage [see Warnings and Precautions (5.12) ] . Prevention or Management Monitor patients who concomitantly use haloperidol decanoate injection with lithium closely for early signs of neurological toxicity, and discontinue haloperidol decanoate injection or both haloperidol decanoate injection and lithium promptly if such signs appear. 1 See www.fda.gov/CYPandTransporterInteractingDrugs for examples of CYP3A4 and/or CYP2D6 inhibitors, CYP3A4 inducers, and CYP2D6 substrates.

Pregnancy and breastfeeding

8.1Pregnancy Risk Summary

Available data from published epidemiologic studies of pregnant patients exposed to haloperidol have not established a drug-associated risk of major birth defects or miscarriage. Case reports of limb malformations in neonates have been reported in haloperidol-treated mothers; however, causal relationships were not established in these cases. There are risks to the pregnant patient from untreated schizophrenia, including increased risk of relapse, hospitalization, and suicide (see Clinical Considerations ) .

Haloperidol decanoate injection should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms (agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and decreased feeding) following delivery (see Clinical Considerations ) .

The estimated background risk of major birth defects and miscarriage in patients with schizophrenia is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively. Clinical Considerations Disease-associated Maternal and/or Embryo/Fetal Risk: There is risk to the pregnant patient from untreated schizophrenia, including increased risk of schizophrenia relapse, hospitalization, and suicide.

Schizophrenia is associated with increased adverse perinatal outcomes, including preterm birth. It is not known if this is a direct result of the illness or other comorbid factors. Fetal/Neonatal Adverse Reactions: Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and decreased feeding have been reported in neonates who were exposed to antipsychotic drugs during the third trimester of pregnancy.

Transient neonatal dyskinesia has also been reported. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Monitor neonates for extrapyramidal, withdrawal, and dyskinesia symptoms and manage symptoms appropriately. Data Animal Data: Rats or rabbits administered oral haloperidol at doses of 0.5 to 7.5 mg/kg (approximately 0.2 to 7 times the maximum recommended human oral dose (MRHD) of 20 mg/day based on mg/m 2 body surface area) showed an increase in incidence of resorption, reduced fertility, delayed delivery, and pup mortality.

No fetal abnormalities were observed at these doses in rats or rabbits. Cleft palate has been observed in mice administered oral haloperidol at a dose of 0.5 mg/kg, which is approximately 0.1 times the oral MRHD based on mg/m 2 body surface area.

6.1Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse Reactions Identified in Clinical Trials with Haloperidol Decanoate Injection The data described below reflect exposure to 15 mg to 500 mg (1.7 times the maximum recommended dosage) of haloperidol decanoate injection monthly in 13 clinical trials of 410 adult patients with schizophrenia or an unapproved condition.

These clinical trials comprised of: 1 double-blind, active comparator-controlled trial with fluphenazine decanoate (Trial 1). 2 trials comparing haloperidol decanoate injection to oral haloperidol (Trials 2 and 3). 9 open-label trials. 1 dose-response trial. The most common adverse reactions that occurred in ≥5% of haloperidol decanoate injection-treated patients in Trial 1 were Parkinsonism and oculogyric crisis. Adverse reactions that occurred in ≥1% of haloperidol decanoate injection-treated patients in Trial 1 are shown in Table 2.

Trial 1 was not designed to evaluate meaningful comparisons of the incidence of adverse reactions in the haloperidol decanoate injection and fluphenazine decanoate treatment groups. Table 2: Adverse Reactions that Occurred in ≥1% of Haloperidol Decanoate Injection-treated Patients and Fluphenazine Decanoate-treated Patients in Trial a Haloperidol Decanoate Injection (n=36) Fluphenazine decanoate (n=36) Extrapyramidal disorder: Parkinsonism 31% 44% Oculogyric crisis 6% 0% Akinesia 3% 22% Akathisia 3% 14% Tremor 3% 0% Abdominal pain 3% 0% Headache 3% 0% a The study was not designed to evaluate meaningful comparisons of the incidence of adverse reactions in the haloperidol decanoate injection and the fluphenazine decanoate treatment groups.

Less common adverse reactions (<1%) that occurred in Trial 1 and other adverse reactions that occurred in Trials 2 and 3, and open-label and dose-response clinical trials of haloperidol decanoate injection are listed below.
