The intravenous route is not FDA approved and is generally not recommended except when no other alternatives are available. Intravenous administration appears to be associated with a higher risk of QT prolongation and torsade de pointes (TdP) than other forms of administration. The manufacturer recommends ECG monitoring for QT prolongation and arrhythmias if IV administration is required. A dose in the range of 1 to 5 mg IV has been suggested, with the dose being repeated at 30 to 60 minute intervals, if needed. A maximum IV dose has not been established. The lowest effective dose should be used in conjunction with conversion to oral therapy as soon as possible.

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.

Herbs and supplements. Increasingly, people with sleep difficulties have been turning to herbal remedies instead of sedative-hypnotic drugs such as the BZDs. Melatonin (5-methoxy-N-acetyltryptamine), a hormone released from the pineal gland (a small pine-cone shaped structure in the brain) is essential in regulating circadian rhythms (approximately 24-hour intervals). In mammals, the melatonin rhythm is generated by an internal circadian clock in the hypothalamus region of the brain that is linked to the light/dark cycle of the 24-hour day.

Nonadherence to medications is a significant problem; in a recent study, 74 percent of patients discontinued their medication within 18 months. 16 Nonadherence often leads to relapse of symptoms. Atypical antipsychotics were initially thought to help with adherence because of their lower rate of neurologic side effects. However, meta-analyses have found that drop-out rates and relapse prevention are no better with atypical antipsychotics than with neuroleptics. 17 , 18 Meta-analyses also have found that in terms of symptom scores and drop-out rates, atypical antipsychotics are better than high dosages (., more than 12 mg per day) of haloperidol (Haldol); there was no advantage when the dosage of haloperidol was less than 12 mg per day. 17 In other words, many of the perceived benefits of atypical antipsychotics actually were a result of the excessive doses of first-generation antipsychotics that were used for comparison in randomized trials. 17 Evidence suggests that delays in initiating therapy with antipsychotics may result in a lifetime deleterious effect on psychotic episodes and social adjustment. 19 , 20 If initiation of antipsychotic therapy is delayed because of limited psychiatric resources, family physicians should consider starting medications instead.
