If you've already developed allergic rhinitis, then you definitely need to pay attention to your diet.
First, you should know which foods are likely to trigger an allergic reaction in you, so it's best to avoid these foods.
At the same time, it's advisable not to eat seafood, as seafood is very likely to induce an allergic reaction.

In addition to dietary precautions, some formal treatment is also required.
You can choose Nasonex or Rhinocort for nasal spray treatment.

When the symptoms are particularly severe, you also need to choose loratadine tablets or cetirizine hydrochloride tablets for oral treatment.
