The surge in allergies this year has been due to a very wet winter and the weather this spring has brought erratic temperatures and lots of wind. The perfect storm for the "allergic cascade" to inflict itself on everyone's nasal mucosa.
The best preventative for nasal allergy symptoms (allergic rhinitis) has been the use of intranasal steroids. These steroid sprays have been used for the past 15 years and clinical studies have shown that intranasal steroids are superior to oral antihistamines.
Intranasal steroids function by inhibiting the production of chemical mediators such as histamine and prostaglandin that cause inflammation and mucous production. In other words they are more of a preventative medication, while an antihistamine is treating the histamine that was released once you inhaled the offending tree or grass pollen. Intranasal steroids may also help eye allergy symptoms too.
The problem is getting young kids to let you use a nose spray on them. The same holds true for the older tween and teen crowd who complain that they "just don't have the time to use it everyday" (it must take all of 15 seconds to use on yourself!) They have been shown to be effective within 3-12 hours, although will reach their maximum effectiveness after several days to weeks of use, so using it daily and throughout the allergy season is going to give you the maximum therapeutic effect.
There are many different brands available and everyone seems to have their favorite. If one spray seems to bother your child due to scent, or intensity of the spray ask your doctor to try another brand. Many times they will have a sample and give you several to try and then prescribe the one that is easiest to get your child to use. It may be trial and error, but finding the right nasal steroid may just change your allergy season.
That's your daily dose, we'll chat again tomorrow. Oh, God Bless You!
