Allergy Shots: That is a decision for you and your allergy doctor to decide. The average time frame is 3-5 years of maintenance therapy. Some people need allergy shots longer.

After getting an allergy shot, how soon can you exercise?

30 minutes: After an allergy shot, you need to wait in the office at least 30 minutes to be certain there are no reactions, so unless there is a treadmill in the office, you can't really exercise then. After that though, if you feel fine, there is no reason to wait to exercise. ...Read more

Are there shots that can permanently alleviate my dog and cat allergies?

Are there shots that can permanently alleviate my dog and cat allergies?

Yes.: Immunotherapy - a series of injections of cat and/or dog dander under the skin over several years - will help you develop some tolerance to pet exposure. Some allergic patients respond better than others and a few patients not at all. Allergy shots alone are often not the complete answer. You may still need to get the pets off the bed, out of the bedroom, & perhaps out of the house. ...Read more

Do allergy oral drops work? Do they work as well as allergy injections? Should I stop the drops and look into shots?

Do allergy oral drops work? Do they work as well as allergy injections? Should I stop the drops and look into shots?

In principle, yes: Allergy drops have been used as off-label allergy treatment for many years and shown to be effective in certain environmental allergies. Its limitation is that it is dose-related meaning doctors could not fit so many allergens into the drop. It also does not work in case of patients with multiple environmental sensitivities shown on allergy testing. In that case, allergy shots would work better. ...Read more

How is it that allergy shots work?

How is it that allergy shots work?

Two main ways: In general terms, immunotherapy induces "blocking" antibodies that remove inhaled allergens from the body before they have a chance to bind to allergic antibodies, and it induces "suppressor" mechanisms of the immune system to stop making allergic antibodies, and to suppress allergic reactions that still occur anyway. That is why it is far more effective than meds, which mask allergy symptoms. ...Read more

No: Allergy shots (immunotherapy) provide marked symptomatic benefit by inducing immunologic tolerance to the airborne allergens to which you have developed sensitivity. They do carry minimal inherent risk of local and systemic allergic reaction (because they contain what you are allergic to) but weight gain is not a reported reaction or side effect. ...Read more
