Central nervous system side effects have included sleepiness, lightheadedness, sedation, sweating, agitation, tremor, mood changes (e.g., euphoria, dysphoria), weakness, headache, disorientation, respiratory depression, delirium, seizures, tremors, dizziness, visual disturbances (e.g., transient hallucinations), muscle twitches, dilated pupils, and Parkinsonian symptoms.
Central nervous system side effects may be either depressant or excitatory. Excitatory symptoms are sometimes ignored as possible side effects of meperidine, but may be due to the accumulation of a metabolite, normeperidine. Accumulation of normeperidine occurs more frequently in patients with renal insufficiency and in patients who are receiving meperidine via a patient-controlled analgesia pump.
Severe adverse effects, such as respiratory depression, may be treated with the opioid antagonist naloxone.
