OBJECTIVE: Topiramate (TPM) therapies for epilepsy or migraine are long-time therapies with unknown mechanisms and special side effects. TPM influences cholesterol (TC) and lipoprotein serum levels. In addition, TPM may cause uric acid (UA) stone formation. MATERIAL AND METHODS: Serum UA, TC, and triglyceride (TG) levels were measured in 53 migraine patients receiving TPM and in 44 age- and sex-matched controls. Compared with controls, patients on TPM showed significantly higher UA and nonsignificantly higher TC and TG values. We recorded pre- and posttreatment levels of UA, TC, and TG levels in 23 patients. RESULTS: We found increased serum levels of UA with TPM use (P < .01). There was a significant and positive correlation between serum UA levels and male gender (P < .01).The changes in serum UA levels before and after TPM treatment differed significantly (P < .01). CONCLUSION: Our results suggest a need for monitoring serum UA levels in patients receiving TPM. We should perhaps prescribe a low-UA diet and advice to drink much more water in these patients.
