Hi I am allergic to pet dander and when in contact with it I get hives so how long will my hives last?
My daughter had undergone squint surgery in both eyes. We have a pet at home, is there risk of infection or irritation because of dander.
Real estate agent: Find one. Buy new house. Leave pet behind. There are no other "quick procedures". Moving pet out is your best solution in long run. Keeping pet off furniture, bedding & out of laundry room helps. A hepa air purifier reduces airborne pet dander as will keeping windows open. For effective hepa calculate volume of home. Hepas must move that amount of air every 10 minutes. It's a big investment. ...Read more

Allergy Testing: Although you may already have a good idea that you are allergic to animals due to symptoms that occur upon exposure, allergy testing will help confirm your suspicions. Please don't be fooled by pet stores that advertise certain breeds as "hypoallergenic" because they don't shed their hair. It is the microscopic bits of skin or dander that cause most of the symptoms, and all dogs shed skin. ...Read more
Very difficult: It is very difficult to get rid of pet allergen, particularly cat or dog allergen, unless the animal is removed from the home.

If you want him not to get allergies when he comes over, then you have to get rid of your animal

What should I do if I'm consistently wheezing when I exhale? I've been working around pet dander for over 1 month.
What are some long term effects my son could have if he is highly allergic to dogs and is exposed to large amounts of dog dander for months at a time?
Misery: Chronic exposure to allergens brings about symptoms that will fade when the allergen is removed. If he works around dogs, this may trigger the misery of whatever symptoms he has, but is not going to cause cancer or system failure. Once daily non sedating antihistamines like Allegra may help. Yet the best way to avoid the symptoms is to avoid the triggering factors. ...Read more
One year: Cat dander can remain in the house for one year after removing the pet.

Is there a correlation between Tonsillectomy and increased pet allergies? Particularly, cat dander.
Not likely: There is an association between allergic rhinitis in general (pollens, dust mite, animal dander etc) and childhood andenotonsillar hypertrophy.

The tonsils house many controller cells that drive (or inhibit) antibody responses to infection so it is conceivable. ...Read more

Don't: If he is really allergic to dogs, getting a dog could make your father feel very ill with constant exposure. He could be desensitized with allergy shots but that would take 3-5 years. You could get an outdoor dog and tuna HEPA filter indoors to reduce levels of dog allergen. See an allergist to discuss options. ...Read more
Have cat allergies. Considering moving to apartment. Next door neighbor has cat & balconies touch each other's. Am I screwed, does dander wander?
Airborne dander: Hard to say if you will have a problem, but I do hear from patients who do feel that they are having allergic reactions to the smoke or cat/dog dander from next door. Animal dander is very light and remains airborne for many hours, so it is conceivable that it could travel through the ventilation system into your apartment. ...Read more

Don't know: If the airborne allergens are indeed causing your facial swelling and your swelling has not responded to cetirizine, youmay have to wait until after the exposure has stopped. If the problem is severe and avoidance impossible, a short course of Prednisone may be necessary to tie you over. ...Read more
