It’s allergy season! Prevention and treatment is important if you have seasonal allergies so you can enjoy the great outdoors. This is an update to a previous blog I wrote on the subject, since there are many more medicines now available over the counter.
Symptoms of Allergies:
Allergies can impair sleep (leading to all the problems associated with not enough sleep) and can lead to the annoying symptoms of itching, coughing, sneezing, runny nose, and watery eyes. Some kids get a crease across their nose from wiping. Others get purple circles under their eyes called allergic shiners.
These symptoms last longer than the typical cold, which usually resolves after 1-3 weeks. Fever is a sign of infection, not allergies. Other than fever, it is very difficult sometimes to decide if it is a virus or allergies until a seasonal pattern really develops. Even then it is possible to get colds during allergy season some years!
It is best to treat before the symptoms get bad. It is easy to monitor pollen counts online to know what’s out there and start treatment before symptoms make you (or your child) miserable. Treatments include medicines and limiting exposure.
I don’t want kids with outdoor allergies to be afraid to go outside, so taking medicines to keep the symptoms at bay while out can help.
- Antihistamines work to block histamine in the body. Histamine causes the symptoms of allergies, so an antihistamine can help stop the symptoms. Some people respond well to one antihistamine but not others. In general I prefer the 24 hour antihistamines simply because it is impossible to cover the full day with a medicine that only lasts 4-6 hours. Different antihistamines work better for some than others. Personally loratadine does nothing for me, fexofenadine is okay, but cetirizine is best. I have seen many patients with opposite benefits. You will have to do a trial period of a medicine to see which works best. If they make your child sleepy, giving at bedtime instead of the morning might help. Prescription antihistamines are available, but usually an over the counter type works just as well and is less expensive. Insurance companies rarely cover the cost of antihistamines these days.
- Antihistamine and decongestant combinations are available but are not usually recommended by me. Once control of the mucus is achieved, a decongestant isn’t needed. If you need a decongestant initially, you can use one with your usual antihistamine. Most decongestants on the market are ineffective. If you ask the pharmacist for pseudoephedrine, it is available behind the counter. It was replaced by phenylephrine years ago due to concerns of methamphetamine production, but works a little better than phenylephrine. Decongestants do NOT fix a cold, they only dry up some of the mucus. Decongestants can cause dizziness, heart flutters, dry mouth, and sleep problems, so use them sparingly and only in children over 4 years of age.
- Nasal spray steroids and antihistamines are available over the counter or as a prescription. An office visit to discuss the value of these for your child and proper use is recommended. Nasal steroids are often the preferred treatment based on effectiveness and tolerability.
- Eye drops can help alleviate eye symptoms. They are available both as over the counter allergy drops and prescription allergy eye drops. If over the counter drops fail, make an appointment to discuss if a prescription might help better. Most insurance companies don’t cover prescription allergy eye drops well, so you might want to check your formulary before asking for a prescription. This is usually available on your insurance website after you log in. Tips to administer eye drops include washing hands before using eye drops, put the drop on the corner of the closed eye (nose side) and then have the child open his eyes to allow the drop to enter the eye.
- Singulair (Montelukast) works to stop histamine from being released into the body. It helps control both allergies and asthma and is best taken in the evening. Once a person has been on montelukast for a couple of weeks, they usually don’t need an antihistamine any longer. It is available only by prescription, so make an appointment to discuss this if your child might benefit.
- Steroids decrease allergic inflammation well. These can include both oral steroids for severe reactions (such as poison ivy on the face or an asthma attack) and inhaled corticosteroids for the nose (or lungs in asthma). These require a prescription, so a visit to your provider is recommended to discuss proper use.
The longer your airway is exposed to the allergen (pollen, grass, mold, etc) the more inflammation you will have.
- Wash hair, eyelashes, and nose after exposures — especially before sleep. They all trap allergens and increase the time your body reacts to them. I have found the information and videos on Nasopure.com very helpful to teach kids as young as 2 years to wash their noses. (Note: I have no financial ties to Nasopure… I just love the product and website!)
- Remove clothing and shoes that have pollen on them when entering the house to keep pollen off the couch, beds, and carpet.
- Wash towels and sheets weekly in hot water.
- Vacuum and dust weekly. Consider cleaning home vents. Consider hard flooring in bedrooms instead of carpeting.
- Wash stuffed animals and other toys regularly and discourage allergic children from sleeping with them.
- There are many types of air filters that have varying benefits and costs. For information on air filters see this pdf from the Environmental Protection Agency: Aircleaners.
- Keep the windows closed. Sorry to those who love the “fresh air” in the house. For those who suffer from allergies, this is just too much exposure!
- Keep pets out of bedrooms. If you know a family member is allergic to an animal, don’t get a new pet of this type! If you already have a loved pet someone in the home is allergic to, consider allergy shots against this type of animal.
- If itchy eyes are a problem for contact lens wearers, a break from the contacts may help. Talk with your eye doctor if eye symptoms cause problems with your contacts.
- Keep smoke away. Smoke is an airway irritant and can exacerbate allergy symptoms. Remember that the smoke dust remaining on hair, clothing, upholstery, and other surfaces can cause problems too, so kids can be affected even if you don’t smoke near them.
What if all of the above isn’t helping?
Maybe it’s really not allergies.
- Allergies to things other than foods are rare before 2 years of age.
- Viruses can cause very similar symptoms to allergies.
- Allergy testing is possible by blood or skin prick testing, but can be costly. In most cases I don’t find it very helpful for environmental allergens because you can’t avoid them entirely and you can always limit exposures as above. I think that tracking seasonal patterns over a few years can identify many of the allergens. You can still treat as needed during this time. Reports of pollen and mold counts are found on Pollen.com. Note also animal exposures and household conditions. Write symptoms and exposures weekly (or daily). It often doesn’t take long to see patterns. Testing is important if allergy shots are being considered.

Wrong medicine or wrong dose.
- Some people have more severe allergies and need more than one treatment. Allergies tend to worsen as kids get older. Switching types of medication or adding another type of medicine might help. If you need help deciding which medicine(s) are best for your child, an office visit for an exam and discussion of symptoms is advised.
- Some kids outgrow a dose and simply need a higher dose of medicine as they grow.
Is Nothing working?
Consider allergy shots (immunotherapy) to desensitize against allergens if symptoms persist despite your best efforts as above. Schedule an appointment with your pediatrician to discuss if this is an option for your allergy sufferer.
