Plain English Summary
Background and study aims
A vestibular migraine is a nervous system problem that causes repeated dizziness (or vertigo). The attacks of vertigo can be associated with headaches and other migraine-typical symptoms such as need for rest, and sensitivity to light and/or noise. Most patients additionally suffer from migraine with or without aura. The diagnosis of patients with vestibular migraine is usually based on the typical medical history and response to drug treatment. The preventative treatment of vestibular migraine corresponds to the treatment of migraine with aura, but its effectiveness for vestibular migraine has not yet been proven. The aim of this study is to review this treatment method.
Who can participate?
Patients aged 18 to 80 with vestibular migraine
What does the study involve?
Participants are randomly allocated to receive the drug metoprolol or a placebo (dummy) treatment for 6 months. During the 6-month treatment, four examination appointments and three telephone interviews take place, as well as a follow-up appointment 3 months after stopping the medication. All examination appointments take place on an outpatient basis. The number of vertigo attacks and number of migraine attacks are compared in the two treatment groups during the last 3 months of the 6-month treatment period.
What are the possible benefits and risks of participating?
During the study, participants receive care that exceeds the level of usual care. Measurements are painless. The drug metoprolol (beta-blocker) has been well-known for many years and is widely and successfully used in both conventional migraine and cardiovascular (heart) diseases. The risk of serious or unknown side effects is therefore low, especially in the placebo group. Costs for the journey to the outpatient examination will be refunded.

Prophylactic treatment of vestibular migraine with metoprolol: a double-blind, placebo-controlled trial
Acronym
PROVEMIG
Study hypothesis
Metoprolol (95 mg per day) is more effective in reducing the number of vertigo attacks and headache attacks in vestibular migraine than placebo.

2. At least two attacks per month for at least 3 subsequent months
3. Aged 18 to 80 years, either sex
