| Antihistamines are used to relieve
or prevent the symptoms of hay fever and other types of allergy.
They work by preventing the effects of a substance called histamine,
which is produced by the body. Histamine can cause itching,
sneezing, runny nose, and watery eyes. Also, in some persons
histamine can close up the bronchial tubes (air passages of
the lungs) and make breathing difficult.
Some of the antihistamines are also used to prevent motion
sickness, nausea, vomiting, and dizziness. In patients with
Parkinson's disease, diphenhydramine may be used to decrease
stiffness and tremors. Also, the syrup form of diphenhydramine
is used to relieve the cough due to colds or hay fever. In
addition, since antihistamines may cause drowsiness as a
side effect, some of them may be used to help people go to
sleep.
Hydroxyzine is used in the treatment of nervous and emotional
conditions to help control anxiety. It can also be used to
help control anxiety and produce sleep before surgery.
Some antihistamines are used in the treatment of chronic
urticaria, which is a persistent hive-like rash.

| precautions |
|
Before you have any skin tests
for allergies, tell the doctor in charge that you are taking
this medicine. The results of the test may be affected by this
medicine.
When taking antihistamines on a regular basis, make sure
your doctor knows if you are taking large amounts of aspirin
at the same time (as for arthritis or rheumatism). Effects
of too much aspirin, such as ringing in the ears, may be
covered up by the antihistamine.
Antihistamines will add to the effects of alcohol and other
CNS depressants (medicines that slow down the nervous system,
possibly causing drowsiness). Some examples of CNS depressants
are sedatives, tranquilizers, or sleeping medicine; prescription
pain medicine or narcotics; barbiturates; medicine for seizures;
muscle relaxants; or anesthetics, including some dental anesthetics.
Check with your doctor before taking any of the above while
you are using this medicine.
This medicine may cause some people to become drowsy or
less alert than they are normally. Even if taken at bedtime,
it may cause some people to feel drowsy or less alert on
arising. Some antihistamines are more likely to cause drowsiness
than others. Drowsiness is less likely with cetirizine, and
rare with desloratadine and loratadine. Make sure you know
how you react to the antihistamine you are taking before
you drive, use machines, or do anything else that could be
dangerous if you are not alert.
Antihistamines may cause dryness of the mouth, nose, and
throat. Some antihistamines are more likely to cause dryness
of the mouth than others . For temporary relief of mouth
dryness, use sugarless candy or gum, melt bits of ice in
your mouth, or use a saliva substitute. However, if your
mouth continues to feel dry for more than 2 weeks, check
with your medical doctor or dentist. Continuing dryness of
the mouth may increase the chance of dental disease, including
tooth decay, gum disease, and fungus infections.
For patients using dimenhydrinate, diphenhydramine, or hydroxyzine:
This medicine controls nausea and vomiting. For this reason,
it may cover up the signs of overdose caused by other medicines
or the symptoms of appendicitis. This will make it difficult
for your doctor to diagnose these conditions. Make sure your
doctor knows that you are taking this medicine if you have
other symptoms of appendicitis such as stomach or lower abdominal
pain, cramping, or soreness. Also, if you think you may have
taken an overdose of any medicine, tell your doctor that
you are taking this medicine.
For patients using diphenhydramine or doxylamine as a sleeping aid:
If you are already taking a sedative or tranquilizer, do
not take this medicine without consulting your doctor first.
