Here’s a look at some of the most popular allergy drugs currently on the market, and what medical experts say about them:
Over the counter:
* Antihistamine tablets and liquids like Benadryl, Dimetapp and Chlor-Trimeton.
These drugs effectively block the production of histamine, the body chemical that causes hives, itching and nasal congestion, but they result in drowsiness and slowed reactions.
“Studies show they impair your driving ability more than being intoxicated,” warned Marjorie Slankard, co-director of the Allergy Clinic at New York Presbyterian Hospital.
* Nasalcrom nasal spray safely decreases nasal swelling; other nasal sprays such as Afrin and Neo-Synephrine can cause more congestion if used for more than a few days.
Prescription:
* Antihistamines Allegra, Claritin and Zyrtec are all considered better options than over-the-counter versions because they are non-sedating.
“There’s no clear-cut way to choose among them – it depends on the individual,” said Ira Finegold, chief of the Allergy Division at St. Luke’s-Roosevelt Hospital.
* Cortisone nasal sprays such as Rhinocort, Nasonex and Flonase relieve stuffy noses by reducing swelling in nasal passages and are often used in conjunction with prescription antihistamines.
“They’re as effective as steroids in reducing inflammation but since they’re not absorbed in the bloodstream, don’t have the side effects of actually taking steroid pills,” explained Slankard.
Some physicians have anecdotally reported growth problems in children using these drugs, but no published studies support this claim.
* Antihistamine eye drops such as Naphcon-A or Patanol can relieve itchy, burning eyes.
* Asthma drugs such as Accolate and Singulair have recently been shown to reduce allergy symptoms in sufferers.
