CNS depression potentiated with alcohol, other CNS depressants. Possible neurotoxicity with lithium: monitor, discontinue if occurs. Caution with drugs that prolong the QT interval (eg, ketoconazole, paroxetine). May be potentiated by CYP3A4 inhibitors/substrates or CYP2D6 enzymes (eg, itraconazole, nefazodone, buspirone, venlafaxine, alprazolam, fluvoxamine, quinidine, fluoxetine, sertraline, chlorpromazine, promethazine. May be antagonized by CYP3A4 inducers (eg, rifampin, carbamazepine); monitor and adjust doses. May increase intraocular pressure with anticholinergics. Monitor anticoagulants.
There are no well controlled studies with Haldol (haloperidol) in pregnant women. There are reports, however, of cases of limb malformations observed following maternal use of Haldol along with other drugs which have suspected teratogenic potential during the first trimester of pregnancy. Causal relationships were not established in these cases. Since such experience does not exclude the possibility of fetal damage due to Haldol, this drug should be used during pregnancy or in women likely to become pregnant only if the benefit clearly justifies a potential risk to the fetus.
Consequently, it is recommended to leave all but absolutely essential medicines at home if you are going to or via Dubai, even as a transit passenger. In some cases the consequences are pretty severe, but many other people have been inconvenienced to the extent of being detained for some hours before being released. One might say “no harm done”, unless of course, it happens to you. A few hours of detention by customs officials is not at all pleasant anywhere in the world, but all the more so if people are shouting at you in a language that you do not understand.
