Increased blood triglycerides (first report withbaclofen): case report

A 39-year-old man developed an increased level of bloodtriglycerides while receiving baclofen and risperidone [routesnot stated].

The man started baclofen 20 mg/day for alcoholdependence, which was gradually increased to 180 mg/dayafter 5 weeks. He had been receiving lithium for bipolardisorder; however, he presented with signs of lithiumoverdose 7 weeks after starting treatment. Lithium wasswitched to risperidone 1 mg/day. One week later, hisrisperidone dosage was increased to 2 mg/day and hisbaclofen dosage was gradually increased to 240 mg/day. Onemonth later, tests revealed a serum triglyceride level of6.56 g/L and a total cholesterol level of 1.78 g/L. A few dayslater, he stopped drinking. Due to persistence of manicsymptoms, his risperidone dosage was increased to 4 mg/day2 months later. After a further 1.5 months, his risperidonedosage was increased to 6 mg/day. One week later, testsrevealed a serum triglyceride level of 41 g/L and a totalcholesterol level of 7.81 g/L, which induced hyponatraemia.Over the past month, his weight had increased by 10kg.

Risperidone and baclofen were withdrawn, and he receivedcarbamazepine. His triglyceride level decreased to 2 g/L after15 days. Three months later, he had no mood symptoms andremained abstinent, while triglyceride levels were normal.
