Higher rates of carbapenem‐related seizures in older hospitalised adults

Abstract Clinical experience suggests higher occurrence of carbapenem‐associated seizures in the elderly than what is reported in the available literature (range between 0.2% and 0.7%). An audit of 1345 patients with age 60 years or older, who received imipenem, ertapenem or meropenem during their acute hospitalisation found 32 (2.4%) subjects developed seizures. Subjects with more than one central nervous system disorders were 11.6 times more likely to develop seizures (odds ratio 11.61, P < 0.001) and subjects with prior history of seizures is associated with four times greater risks (odds ratio 4.02, P = 0.005). Physicians should exercise caution when prescribing carbapenems in elderly, especially those with known epilepsy and a high number of intracranial pathologies.
