How long can I expect the effects of allergy drops to last?

A benefit of immunotherapy (shots and drops), is that it can actually change the course of allergic disease by treating the root cause, not just the symptoms. Once allergic tolerance is built, it can be permanent for many patients.

But even the best treatments won’t work if you don’t stay with them. Like allergy shot treatment, it’s important to stay with allergy drop treatment until your provider has determined it can be discontinued to give you the best chance of long-term effectiveness.
