To study the efficacy of the combination of albendazole and prednisolone for the treatment of eosinophilic meningitis, we conducted a pilot study among Thai patients with eosinophilic meningitis. Patients were given a 2-week course of prednisolone, 60 mg/day and albendazole, 15 mg/kg/ day. The primary observation parameter was the number of patients who still had headache after the 2-week course of treatment. Twenty-six patients were enrolled in the study. There were 3 (11.5%) patients who still had headache after the 2-week course of treatment and the median length of time until complete disappearance of headache was 4 days. Serious side effects were not detected. Treatment for 2 weeks with the combination regimen of albendazole and prednisolone is safe and effective for the treatment of eosinophilic meningitis.
