Here’s a holiday tale that happens over and over again. You’re an animal lover. You’re a college student and get to come home for Thanksgiving to see your family and your cat! Cats have been a part of your life since age 5, but in the past six months, what were mild allergy symptoms have gotten worse, causing sneezing, itchy, puffy eyes, and hives. Allergy tests have proven what her family suspected. Oops!
An estimated 40 million to 50 million Americans suffer from asthma or other allergic diseases, and the incidence is increasing. Asthma rates alone have more than tripled in 25 years, now affecting more than 22 million people. Why?
Theories include not only allergy, but irritants such as air pollutants, dietary changes and changes in lifestyle. Genes also are a factor, and people who have allergies are also more sensitive to irritants. So what are some of these irritants that you can’t treat with allergy shots?
•Air fresheners and scented candles: Sometimes, the irritating trigger is right under your nose. But don’t listen to just me. Atlanta allergist Stanley Fineman, president-elect of the American College of Allergy, Asthma, and Immunology says, “I’ve been seeing more and more adults who are having problems with air fresheners–they’re coming in with all kinds of symptoms,” from sneezing and congestion to headache, coughing, fatigue and asthma.
Candles and air fresheners may emit volatile organic compounds, or VOCs, such as formaldehyde, petroleum distillates, limonene and other substances that increase asthma risk in children and can trigger eye and respiratory irritation and other health problems.
Treatment plans might include medication, changes in home décor or other avoidance strategies, but it starts with being aware. “People with asthma or respiratory sensitivity need to take precautions,” Fineman says, and doctors “may not have air fresheners on their radar screen. It’s helpful if we start thinking about that as another potential problem.” Keep in mind, however, that allergy shots DON’T work for irritants such as odors.
•Alcoholic beverages:Reactions to wine or other alcohol-containing drinks are rare, but symptoms can range from rash to severe asthma attacks, says allergist Sami Bahna,
chief of allergy and immunology at Louisiana State University Medical School in Shreveport.
Potential allergens that occur naturally in beer and wine include hops, barley, ethanol, grapes, tryptamine, tyramine, wheat and histamine, and there may be added ingredients such as egg whites or sulfites, he says. “About a third of asthmatics can have difficulty with alcohol,” possibly in reaction to sulfites or other preservatives, he says.
In some cases, a mild allergy to a wine ingredient pairs up with a mild allergy to something in food, such as cheese, and the combination can cause an allergic reaction.
•Pets: More than 90% of homes have “measurable dog and cat allergens,” even those that don’t have a resident pet, says allergist Dana Wallace, president of the American College of Allergy, Asthma, and Immunology.
Animal dander, particularly cat dander, is “light and airborne for a long time.” People track it from their homes into stores, schools and homes of friends.
She advises patients to find new homes for the pets, but “in 30 years of practice, I can count on one hand the number who have willingly given up a pet.” Because it’s almost impossible to avoid pet dander anyway, she says, allergy shots are usually recommended to help patients tolerate exposure.
Patients are often willing to keep cats out of the bedroom, but “I refuse to get rid of them,” many patients say. “They’re definitely a part of the family.”
So what about you? Are you willing to give up the holiday scents, a good glass of wine, or indoor pets just for the sake of allergy?
