Re: Can allergy shots wear off over time?
Yes. The effectiveness of the shots can wear off over time. For me, it was about 6 years after finishing my immunotherapy treatments. I know people who have gone about a decade before seeing some symptoms return.
When I had my new round of allergy testing, some of the allergens were better than they had been, but others had returned. I'm currently in my second go-round of immunotherapy.
