MATERIALS and METHODS: Forty patients with complaints of vertigo and dizziness volunteered to be included in the study. All patients who were included the study were treated at the other medical centers. The patients were divided into two Groups. Patients in the first Group were given betahistine 24 mg three times per day. During this treatment, caloric testing was performed, and the dose was increased to 48 mg three times a day due to ongoing complaints. The test was then repeated four weeks after using this higher dosage. Patients in the second Group had caloric testing while using and four weeks after stopping dimenhydrinate.
