Pet allergy symptoms appear during or shortly after exposure to the animal. Allergies to pets, particularly to cats and dogs, are a common cause of allergic disease, including asthma and allergic rhinitis (hay fever).These symptoms may linger long after the animal is gone. This is because the dander remains in the air, on furniture or on your clothing. The allergy results in: Sneezing, Itchy, watery eyes, Runny nose, Congestion. Additionally, contact with a pet may trigger skin allergy symptoms including itchy skin or raised, red patches (hives). Pets can also trigger asthma symptoms, causing wheezing, difficulty breathing or chest tightness.
The most effective way to manage pet and other allergic rhinitis symptoms is to avoid the allergen(s) causing the symptoms. Antihistamines like Allegra, Claritin, Benadryl, or Zyrtec and other over-the-counter allergy medications may help relieve symptoms, but they are not ideal as a long-term treatment. Decongestants, which reduce swelling in the nose and relieve congestion; examples are over-the-counter Sudafed and Allegra-D. Other drugs, which affect allergy or asthma symptoms in different ways; prescription steroids -- such as Flonase or Nasonex sprays -- are a common treatment for allergies. Both Flonase and Nasonex are available over the counter and by prescription. Allergy shots have a proven track record as an effective form of long-term treatment (immunotherapy).
In Mexico, few studies have evaluated indoor allergens, including cat, dog, and mouse allergens and the factors that predict their presence. This study evaluates the main environmental and household predictors of high prenatal allergen levels and multiple allergen exposures in a birth cohort from Mexico City.
Eighty-five percent of homes had at least one allergen in dust over the detection limit, 52.1% had high exposure (four or more allergens above detectable limits), and 11.7% of homes had detectable levels for more than eight allergens. Der p 1, Der p 2, Mus m 1, and Fel d 1 were the most frequent allergens detected. A prevalence of 7% has been reported for allergic rhinitis among adults in Latin America,and 12% for asthma5 and 26% for allergic rhinitis among children in Mexico.
