Antihistamines are among the most
commonly used medicines to reduce the symptoms of
motion sickness. They block motion signals to the
brain. These medicines include:
- Dimenhydrinate (such as
Dramamine).
- Diphenhydramine (such as
Benadryl).
- Meclizine (such as Antivert and Bonine
tablets).
- Trimethobenzamide (such as
Tigan).
- Cinnarizine.
The medicines can be taken before travel and repeated during
extended travel according to the directions on the package.
Drowsiness is the main side effect of antihistamines. In children,
antihistamines can have the opposite effect, making children excited rather
than sleepy. Antihistamines can also cause
dizziness. Don't give antihistamines to your child
unless you've checked with the doctor first.
- People who have
emphysema or other breathing difficulties or
glaucoma should consult a doctor before taking
antihistamines.
- People who have asthma, high blood pressure,
hyperthyroid disease, or cardiovascular disease should consult a doctor before
taking antihistamines.
Dimenhydrinate, diphenhydramine, and some preparations of
meclizine (such as Bonine) are available without a prescription.
