Allergy relief for children

U.S. Food and Drug Administration (FDA)

When a child’s sniffles and sneezing doesn't go away for weeks, the cause might be allergies. Long-lasting sneezing, with a stuffy or runny nose, could signal the presence of allergic rhinitis — the collection of symptoms that affect the nose when you have an allergic reaction to something you breathe in, and it lands on the lining inside the nose.

Allergies can be seasonal or year-round (perennial). In most parts of the U.S., plant pollens are often the cause of seasonal allergic rhinitis, more commonly called hay fever. Indoor substances — such as mold, dust mites and pet dander — can cause the perennial kind.

Up to 40% of children suffer from allergic rhinitis. And children are more likely to develop allergies if one or both parents have allergies.

The U.S. Food and Drug Administration regulates nonprescription (over-the-counter, or OTC) and prescription medicines that offer allergy relief, as well as allergen extracts used to diagnose and treat allergies. Take care to read and follow the directions when giving any medicine to children, including over-the-counter products.

Allergy: The Body’s Reaction to Allergens

An allergy is the body’s reaction to a usually harmless substance, or allergen. Our immune system responds to the invading allergen by releasing histamine and other chemicals that typically trigger symptoms in the nose, lungs, throat, sinuses, ears, eyes or skin.

In some children, allergies can also trigger symptoms of asthma, a disease that causes wheezing or difficulty breathing. If a child has allergies and asthma, not controlling the allergies can make asthma worse.

Avoid Pollen, Mold and Other Allergy Triggers

If your child has seasonal allergies, pay attention to pollen counts and try to keep your child inside when the levels are high.

Keep in mind:

• In late summer and early fall, during ragweed pollen season, pollen levels are highest in the morning.
• In spring and summer, during the grass pollen season, pollen levels are highest in the evening.
• Some molds, another allergy trigger, may also be seasonal. For example, leaf mold is more common in fall.
• Sunny, windy days can be especially troublesome for pollen allergy sufferers.
• It may help to keep windows closed in your house and car and run the air conditioner.

Allergy Medicines for Children

For most children, symptoms may be controlled by avoiding the allergen, if known, and using nonprescription medicines. But if a child’s symptoms are persistent and not relieved by nonprescription medicines, see a health care professional.

Always read the product label to make sure a medication is right for your child’s age. Some OTC allergy medicines are approved for children as young as 6 months — but not all. Just because a product’s box says it’s intended for children, doesn’t mean it is intended for children of all ages.

If your child is taking more than one medication, read the label to be sure that the active ingredients aren’t the same. Different products marketed to treat different symptoms might still have the same active ingredient. The result: Your child might be taking too much of one type of medicine.

Children are more sensitive than adults to many drugs. For example, some antihistamines can have harmful side effects at lower doses in young patients, causing excitability or excessive drowsiness.

If you have questions about any medication, contact the FDA’s Division of Drug Information by phone at 1-855-543-3784 and 1-301-796-3400, or by emaill at druginfo@fda.hhs.gov. FDA pharmacists are experts at interpreting information for the public.

Allergy Shots and Children

Children who don’t respond to other nonprescription or prescription medications, or who suffer from frequent complications of allergic rhinitis, may be candidates for allergen immunotherapy, commonly known as allergy shots.

After allergy testing, typically by skin testing to detect what allergens your child may react to, a health care professional injects the child with “extracts,” small amounts of the allergens that trigger a reaction. The doses are gradually increased so that the body builds up immunity to these allergens. Allergen extracts are manufactured from natural substances, such as pollens, insect venoms, and animal hair. More than 1,200 extracts are licensed by the FDA.

In the last 20 years, there has been a remarkable transformation in allergy treatments. Children used to be miserable for months out of the year, and drugs made them incredibly sleepy. Today’s products offer proven approaches for relief of seasonal allergy symptoms.
