How It Works
Diazepam and clonazepam have a calming effect. They may be able to help with vertigo by reducing the activity of the brain and reducing anxiety. They also can help limit nausea and vomiting.
Why It Is Used
Sedatives are prescribed to control vertigo caused by inner ear problems. This is an unlabeled use of these medicines.
How Well It Works
These medicines do give some people relief from vertigo and nausea. But there is no scientific evidence to show that these medicines help with symptoms of vertigo.1
Side Effects
The most commonly reported side effects are drowsiness, fatigue, and loss of coordination (ataxia).
The U.S. Food and Drug Administration (FDA) has issued a warning on clonazepam (Klonopin) and the risk of suicide and suicidal thoughts. The FDA does not recommend that people stop using this medicine. Instead, people who take clonazepam should be watched closely for warning signs of suicide. People who take clonazepam and who are worried about this side effect should talk to a doctor.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
Sedatives can be habit-forming in some people if they are used over a long period of time or if the person has other drug addictions, including alcohol.
