Brief Answer:
Prevention...

Detailed Answer:
Hi,

If you are allergic, unless desensitized to the allergens the symptoms of allergy will continue to bother you as and when exposed to it. The ideal means to treat an allergic individual is to find out the causative allergen and preventing it. There are skin patch tests that are used to identify common allergens.

You may also consider using an antihistamine / steroid preparation as and when you notice allergic symptoms.

You may also consider other forms of treatment like herbal which may be helpful in some cases.

Hope this answered your question. Let me know if you need clarifications.

Regards
