Patients receiving anticoagulants. Discontinue upon signs of neurological toxicity in patients taking haloperidol and lithium.
Lactation: Drug enters breast milk; not recommended
Pregnancy-Lactation
Pregnancy
There are no well controlled studies in pregnant women; there are reports of cases of limb malformations observed following maternal use with drug along with other drugs which have suspected teratogenic potential during first trimester of pregnancy; causal relationships were not established in these cases; however, such experience does not exclude possibility of fetal damage due to therapy; drug should be used during pregnancy or in women likely to become pregnant only if benefit clearly justifies a potential risk to fetus; infants should not be nursed during drug treatment
Neonates exposed to antipsychotic drugs during third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery; there have been reports of agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder in these neonates; these complications have varied in severity; while in some cases symptoms have been self-limited, in other cases neonates have required intensive care unit support and prolonged hospitalization
Lactation
Drug is excreted in human breast milk; infants should not be nursed during drug treatment
Interactions
Carbamazepine and rifampicin reduce plasma concentrations. Symptoms of CNS depression may be enhanced by CNS depressants e.g. alcohol, hypnotics, general anaesthetics, anxiolytics and opioids. May reduce antihypertensive action of guanethidine. May increase risk of arrhythmia when used with drugs that prolong QT interval or diuretics that can cause electrolyte imbalance. May increase plasma levels of haloperidol when used with clozapine or chlorpromazine.
Potentially Fatal: Increases lithium blood levels and may predispose to neuroleptic malignant syndrome.
