After 5 months of therapy, the patient noticed progressive fatigue, anorexia, dizziness, weakness, light-headedness, decreased concentration, and new-onset falls.

The intranasal desmopressin was discontinued and the patient was admitted to the intensive care unit where the hyponatremia was slowly corrected over the next week to 132 mmol/L, never increasing by more than 8 mmol/L a day, with careful fluid management. This included infusion of over 11 L of 5% dextrose to account for a high urine output, which peaked at 7.4 L in 1 day.

After treatment with levodopa/carbidopa, selegiline, and piribedil, the patient's motor symptoms were improved while no significant effects were observed on psychotic symptoms. A clinical pharmacist analyzed the pharmacologic and pharmacokinetic characteristics of selegiline and piribedil, summarized the scheme of PD with psychotic symptoms in the literature, and discovered that selegiline might potentiate psychotic side effects of piribedil, while the use of levodopa/carbidopa cannot be ruled out either. Finally, the clinical pharmacist proposed to reduce the dosage of levodopa/carbidopa, increase the dosage of selegiline and quetiapine, and discontinue piribedil. The clinician accepted this suggestion. After the adjustment of medication, the patient's motor symptoms were absolutely improved and the psychotic symptoms were notably improved. This case study suggests that long-term treatment with levodopa/carbidopa and piribedil, along with the progression of the disease itself, could contribute to the emergence of psychotic symptoms in PD.

Such errors can relate to the prescription, dispensation, or administration of drugs. Human factors account for most of these mistakes, but other factors such as infusion pump programming defects should always be considered. Worldwide, medication errors have been reported to affect 2-30% of patients, depending on the institution. Intravenous lipid emulsion (ILE) infusion is frequently used as part of total parenteral nutrition in patients of all ages with feeding and gastrointestinal issues. ILE overdose has been previously reported, with variable clinical outcomes. We report a case of accidental ILE (Intralipid) overdose in a 3-month-old male infant who fully recovered after single-volume blood exchange transfusion. We also review reported cases and summarize potential solutions for ILE overdose. Our review indicates that ILE infusion is a high-risk medication, and opportunities for errors remain even in the best hospital set-ups. Attention should be directed towards proper prescription, dosing, dispensation, and administration. Most of the cases indicate the safety breach was at the nursing drug-administration level, with improper pump use or programming, together with other fluid infusion rate switching, being the main possible defects. Strategies targeting the areas of weakness in the drug-delivery pathway are needed. Special attention should be paid towards nursing duties and working hours. In addition, nursing staff should receive frequent education sessions and should be required to pass competency modules regularly. An error-prevention plan should be established and implemented. This plan needs full collaboration between physicians, pharmacists, and nursing staff.</p>","PeriodicalId":11364,"journal":{"name":"Drug Safety - Case Reports","volume":"5 1","pages":"13"},"PeriodicalIF":0.0,"publicationDate":"2018-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s40800-018-0079-y","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35927524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
