Cat Allergy Desensitization
Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more
Immune response: In sensitization the immune system has recognized an allergen as foreign to the body & developed an elaborate mechanism to rid itself of the substance on re-exposure. Sensitization involves processing of allergen by dendritic cells that recruit t lymphocytes to instruct b lymphocytes to make a specific class of antibody, ige class, against the allergen. Ige binds to mast cells. You're sensitized. ...Read more
What is the best allergy medication for seasonal allergies like pollen, dust, ragweed, hay fever, dogs, cats, hamsters etc?
There are a few: Not one medicine is better than another....Everyone's system is different...Some people get better with allegra..Others with zyrtec..Others with Claritin or even benadryl (diphenhydramine). These are now over-the-counter...Try some and read the labels. If you don't feel better, see a board certified allergist (www.Acaai.Org). Good luck. ...Read moreSee 1 more doctor answer
No.: Dr. Carter is correct. Food desensitization protocols remain experimental at this time. When and if they become the standard of care, however, they are oral programs involving swallowing or holding in the mouth initially very small and progressively larger amounts of food. Injecting food under the skin is very dangerous and has been abandoned as a method for treating food allergies. ...Read moreSee 2 more doctor answers
Lots of Options: Over-the-counter non-sedating antihistamines like Allergra, Claritin, and Zyrtec are helpful (I like Zyrtec the best). Other treatments include daily steroid nasal sprays and antihistamine eye drops. Avoidance of triggers is also helpful. If you have a cat, keeping it out of the bedroom is important, HEPA filters, washing cat weekly, frequent cleaning. Allergy shots can also be life-changing. ...Read more
Not really: I suggest 3 steps to controlling allergies : 1) avoid the things you are allergic to. 2) take medications to control the symptoms. 3) get 'allergy shots' (immunotherapy) to teach your body to not be "allergic" to those things (immune tolerance). Using a leukotriene antagonist control the symptoms some, but it is not the most effective medication, and is not an equal alternative to immunotherapy. ...Read more
All severe allergies: Epipen (epinephrine) is self injectable Epinephrine and the medication of choice for any severe allergic reaction (anaphylaxis). It is effective for allergic reactions triggers by pet dander, medications, latex, foods, stinging insects, pollens, etc. An allergist may be able to offer other treatment options in an effort to avoid needing epipen (epinephrine). ...Read more

Unfortunately, no: To truly decrease dust mite symptoms, several measures are needed including encasements over bedding, hot water washing, reducing humidity and no carpet or frequent vacuuming.

Does desensitization vaccination works for allergic asthma?I got positive skin prick tests for 4-5 allergens....
Yes: It is effective about 80% of the time. However I'd doubt that getting allergy shots for 4-5 allergens would work for you since most people are allergic to dozens of airborne allergens except in the case of occupational exposure. ...Read more
Very effective: After a true bee/wasp/hornet allergy is determined, there is approximately a 40-60% chance of another systemic reaction occurring if stung again without ever receiving allergy shots. However, if a patient receives allergy shots to the specific allergic venom, the risk of another systemic reaction reduces to less than 3%. Consultation with a board-certified allergist is recommended. ...Read more
Can environmental allergies (food, pollen, dust mites, contrast dye, penicillin) cause a high positive ANA?
I have seen this: While the +ANA is suggestive of SLE there can be other causes - other connective tissue disease, autoimmune thyroid disease, auto immune hepatitis to name some. I have seen a lot of people with + ANAs who only have as another problem a history of allergic reactions and I am convinced that thee allergic reactions can cause a + ANA. Everyone can have very low titters (amount) of ANA. ...Read more
