How It Works
The exact way that an
antihistamine reduces vertigo is not known. Some of
these antihistamines may also reduce nausea and vomiting.
Dimenhydrinate and promethazine are available as an injection,
suppository, or tablet. Diphenhydramine is available as an injection or a
tablet.
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
neuronitis). Dimenhydrinate may be used to prevent and control nausea
and vomiting caused by
chemotherapy.
How Well It Works
Antihistamines control vertigo well
in some people and not at all in other people. It may be necessary to try
several antihistamines to find one that works for you.
Side Effects
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.
