Antihistamines for Vertigo
|Generic Name||Brand Name|
How It Works
Antihistamines block parts of your brain that make you feel sick to your stomach when you have vertigo or motion sickness.
Why It Is Used
Antihistamines may be prescribed to control vertigo that is caused by inner ear problems, including Ménière's disease, inflammation of the inner ear (labyrinthitis), benign paroxysmal positional vertigo (BPPV), and inflammation of the nerve to the inner ear (vestibular neuritis).
Antihistamines may also be used to prevent nausea and other symptoms of motion sickness.
Dimenhydrinate may be used to prevent and control nausea and vomiting caused by chemotherapy.
How Well It Works
These medicines do give some people relief from nausea and vomiting caused by vertigo. But there is no scientific evidence to show that these medicines help with symptoms of vertigo.1
These medicines may help with mild forms of motion sickness.2
The most commonly reported side effect is drowsiness. Do not use a medicine that makes you drowsy if you will be driving or operating dangerous equipment.
Antihistamines may also cause blurred vision or a dry mouth.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
Most antihistamines should be avoided during early pregnancy, if possible.
Don't give antihistamines to your child unless you've checked with the doctor first.
