Hay Fever (Allergic Rhinitis)
What is hay fever?
Hay fever is an allergic reaction of the nose (and sinuses)
to pollen or another substance in the air.
Symptoms include:
- a clear nasal discharge
- an itchy nose with sneezing and sniffing
- itchy, watery eyes (eye allergies)
- sometimes, sinus or ear congestion.
Hay fever is the most common allergy. More than 15% of
people have it.
What is the cause?
Although pollen is usually the cause of hay fever, it can
also be caused by animal dander or something else your child
is allergic to. This allergic sensitivity is often
inherited.
During late April and May the most common pollen causing hay
fever is from trees. From late May to mid-July, the pollen
is usually from grass. From late August to the first frost,
the leading cause of hay fever is ragweed pollen.
How long will it last?
This is a chronic condition that will probably come back
every year during pollen season, perhaps for a lifetime.
Therefore, it is important to learn how to control it.
How can I take care of my child?
- Oral antihistamine medicine
The best drug for hay fever is an antihistamine. It will
relieve nose and eye symptoms. Your child's
antihistamine is __________________________________.
Give ___________________every ________ hours.
Symptoms clear up faster if antihistamines are given at
the first sign of sneezing or sniffing. For children
with daily symptoms, the best control is attained if
antihistamines are taken continuously throughout the
pollen season. For children with occasional symptoms,
antihistamines can be taken on days when symptoms are
present or expected.
The main side effect of antihistamines is drowsiness. If
your child becomes drowsy, switch to a combination
product that contains an antihistamine with a
decongestant (such as pseudoephedrine). If your child
remains drowsy, continue the drug, but temporarily
decrease the dosage. Your child should become tolerant
of the regular dosage in 1 to 2 weeks. Newer
prescription antihistamines cause much less drowsiness
and are FDA approved for use in children over age 6.
Examples are Allegra, Zyrtec, and Claritin.
- Prescription steroid nasal sprays for prevention
If not helped by antihistamines, severe hay fever can
usually be controlled by prescription steroid nasal
sprays. Allergy shots are usually not needed.
Nasal sprays must be used when the nose is not dripping.
Give your child an antihistamine to stop the dripping
before you use the spray. Your child's nasal spray is
_______________________________. Give ______ puff(s) in
each nostril _______ times per day every day. Nasal
sprays do not help eye symptoms. Therefore they are
usually used along with oral antihistamines or eyedrops.
- Pollen removal to decrease symptoms of hay fever
Pollen tends to collect on the exposed body surfaces and
especially in the hair. Shower your child and wash his
hair every night before he goes to bed. Your child
should avoid handling pets that have been outside and are
probably covered with pollen.
- Prevention of hay fever symptoms
Your child's exposure to pollen can be reduced by not
going on drives in the country and by not sitting by an
open car window on necessary drives. He should stay
away from someone cutting the grass during pollen
season. When it is windy or the pollen count is
especially high, he should stay indoors. Close the
windows that face the prevailing winds. Use an air
conditioner rather than an attic or window fan. Fans can
pull in pollen.
If your child's hay fever is especially bad, you could
also take him to an air-conditioned store or theater for
a few hours.
Avoid feather pillows, pets, farms, stables, and tobacco
smoke if any of them seem to bring on symptoms of nasal
allergy.
If your child is allergic to ragweed, you may wish to plan
a vacation to an area that has little or no ragweed. Only
the coastal areas of Washington, Oregon, and California
are free of ragweed pollen.
- Eye allergies associated with hay fever
If your child also has itchy, watery eyes, wash his face
and eyelids to remove pollen. Then apply a cold wet
cloth to the eyelids for 10 minutes. An oral
antihistamine will usually bring the eye symptoms under
control. If not, put 1 drop of long-acting
decongestant eyedrops (a nonprescription item) in the
eyes every 8 to 12 hours for a few days. Ask your
pharmacist to recommend a reliable product.
- Common mistakes
Decongestant nosedrops or nasal sprays usually do not
help hay fever because they are washed out by nasal
secretions as soon as they are put into the nose.
Also, if decongestant nosedrops or nasal sprays are used
for more than 5 days, they can irritate the nose and make
it more congested.
When should I call my child's health care provider?
Call during office hours if:
- Your child's symptoms are not controlled in 2 days with
antihistamines.
- Your child develops sinus pain or pressure.
- You have other concerns or questions.
