No, but you can treat and control your symptoms. You’ll need to do all you can to prevent being exposed to things you’re allergic to -- for example, staying inside on days when the pollen count is high, or enclosing your mattress with a dust-mite-proof cover.
You can also talk to an allergist about immunotherapy in the form of allergy shots or oral tablets or drops. These are what are considered disease modifying treatments. They don’t cure allergies, but they may significantly reduce your sensitivity to your allergy triggers and reduce your allergic response.
Sometimes children outgrow their allergies, particularly those to food.
