Allergy shots: Desensitization, hyposensitization, immunotherapy are all terms to describe allergy shots.

How often does allergy immunotherapy fail? (in terms of not being able to build immunity to allergen?)
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
Does risk for anaphylaxis vary with type of allergen from immunotherapy? Example: pollen, stings, mites, cat, food, etc..
Complex: Risk of anaphylaxis from immunotherapy depends on many factors: identifying the allergens causing the symptoms, severity of symptoms, whether well controlled prior to start of therapy, choosing the right allergens and right concentrations, assessment at each visit prior to administration of therapy, and observation for at least 30 minutes. Very rare in the hands of a competent allergist, good luck ...Read more
Allergy magic bullet: It's different for everyone. Most people respond well to antihistamines like zyrtec, Allegra & claritin, but some do not, & require intranasal steroid sprays. Even that is not enough for some, and medications like singulair (montelukast) or Accolate are used. Beyond that, allergy shots may help better in others. There is no single magic bullet. Check with your doctor, and figure out which is best for you. ...Read more
What if immunotherapy fails and the person needs the medication they're allergic to (pennicillin)? Can the immunotherapy be tried again?
Antibiotic allergy: There is no immunotherapy for penicillin or antibiotics. There are desensitization procedures which are short-lived and allow patients to tolerate the antibiotic they are allergic to for a short-period of time. You will need to seek out an allergist who performs these types of procedures since not all allergists do these procedures. ...Read moreSee 1 more doctor answer
What is an immunotherapy that is used to treat allergic rhinitis, and please advice me what it entails/involves, ie; any medications?
Allergy shots: Allergy shots help patients have fewer allergic symptoms and use less medications. Relevant allergens are diluted and then given weekly in increasing doses until maintenance level is reached- usually within 3-6 months, but maybe longer. Then the interval between shots is increased to every 2-4 weeks. Pt remains on this dose for usually 3-5 years, but this too is variable. Go see an allergist. ...Read more
What if immunotherapy fails to work for someone and they absolutely need to take the medication they're allergic to?
Can you have anaphylactic rxn following first exposure to an allergen (eg medication) or is it usually after subsequent exposures?
Anaphylaxis..: on first exposure doesn't really happen, most of the time, as you need a sensitizing dose, i.e. Previous exposure, even in tiny amount, usually patients don't recall this previous exposure. Anaphylactoid reactions, can happen with certain drugs as morphine, x-ray dyes, and others, resembling exactly anaphylaxis without being an allergic reaction, and anaphylaxis can happen without a cause, rare. ...Read more

I suffer from dust mite allergy for like 5 years. I'm doing immunotherapy shots for 3 years, and no substantial good results.And drugs don't work.Why?
Ask the allergist: Too many variables to answer this. Your diagnosis or shots could be wrong. You should ask the allergist or physician who is prescribing the shots and if you cannot get a satisfactory answer consider a second opinion with another allergist. Look for allergists certified by the american board of allergy and immunology. A good source is the website of the am academy of allergy: aaaai.Org. ...Read moreSee 1 more doctor answer
Depends how: The route of exposure, among other factors (including genetics) determines whether an individual becomes allergic or tolerant of an allergen. Once allergic, for over 100 yrs, it has been known that bypassing respiratory mucous membranes by giving allergy shots leads to tolerance; similarly, new ways of food desensitization involve gradually eating the food in measured amounts. ...Read more
