ALLERGIES AND CHILDREN
SINGULAIR and Your Child: Allergies and children
Many children have seasonal allergies, perennial (year-round) allergies, or both. If you are a parent of a child with allergies, you know how hard it can be on him or her (not to mention on you). Children sometimes cannot (or do not) tell you about their allergy symptoms. There are, however, some signs you may notice that could mean your child has allergies.
Does your child have any of the following symptoms?
- A frequent congested, runny, or itchy nose
- Dark circles under the eyes
- Frequent breathing through the mouth
- Pushing up on the nose with his or her hands (especially younger children)
- Recurrent ear problems
A congested, itchy, runny nose and sneezing are common symptoms of indoor and outdoor allergies, also called indoor and outdoor allergic rhinitis (rye-NITE-iss) or hay fever. These symptoms can affect your child's everyday life. That's why it is so important to talk to your child's healthcare provider about allergy symptoms and allergy treatments.
Facts about kids and allergies:
- When one or both parents have allergies, there is a greater likelihood that their child will too.
- Most allergies first appear during childhood.
- Allergies are more likely to develop in the oldest child in the family.
- Allergies are more common in boys than girls. By adulthood, however, the number of men and women who have allergies is about the same.
Ask your child's healthcare provider about a different way to treat indoor and outdoor allergies.
