The severity of this interaction may be increased when additional CNS depressants are given. Studies comparing young and elderly subjects have shown that advancing age does not have a significant effect on the pharmacokinetics of lorazepam. Symptoms such as hypoactivity, hypotonia, hypothermia, respiratory depression, apnea, feeding problems, and impaired metabolic response to cold stress have been reported in neonates born of mothers who have received benzodiazepines during the late phase of pregnancy or at delivery. If an opiate agonist is initiated in a patient taking a benzodiazepine, use a lower initial dose of the opiate and titrate to clinical response. Elderly or debilitated patients may be more susceptible to the sedative effects of lorazepam. Monitor patients for decreased pressor effect if these agents are administered concomitantly.
