Randomized double-blinded, placebo-controlled clinical trial of famciclovir for reduction of Ménière's disease symptoms

Abstract

Objective: To conduct a clinical trial of famciclovir for symptom control in Meniere's disease.

Study design and setting: Randomized, double-blinded placebo-controlled clinical trial in a tertiary referral center, with 12 subjects in the active treatment arm and 11 subjects in the placebo arm.

Results: There were no serious adverse events. Twenty-five percent of the famciclovir group and 18% of the placebo group showed a reduction in number of vertigo spells, the primary efficacy endpoint. This difference was not statistically significant. All subjects improved in dizziness and health-related quality of life. There was a trend for the famciclovir arm to have less fluctuation in hearing relative to the placebo arm.

Conclusion: No dramatic effects of famciclovir were found on vertigo or dizziness. Some promising effects on reduction of the fluctuation in hearing were observed.

Significance: Famciclovir may suppress the fluctuation of hearing in Meniere's disease, but had a minimal effect on vertigo or dizziness symptoms in this study. The probable multifactorial etiology in Meniere's disease requires that further studies be conducted to determine the effects of antiviral medications.
