Hello, my 19 years old sister loves to have prawns. But she gets allergy also after having prawns. She gets swelling of the lips, tongue, face, throat or other parts of the body. Cough, wheezing and nasal congestion are also there. After this incidence we figured out that she must have allergy due to having prawns. Please provide me some advice on how to get rid of allergic reaction after having prawns?

@parabat Prawn allergy is immunologically mediated reaction to prawn which occurs within minutes to hours after taking prawn. Even a small amount of food is sufficient to trigger allergy symptoms. In some individuals, a food allergy can cause severe allergy symptoms or even a life-threatening reaction called anaphylaxis. Avoidance is the best preventive measure. However an individual may unknowingly come in contact with the food and lead to allergic reaction. For mild to moderate allergic reaction over-the-counter or prescribed antihistamines are helpful. For severe allergic reaction If there is severe reaction or anaphylaxis one must inject adrenaline/ epinephrine in appropriate dosage. If someone has adrenaline autoinjector then he can use it otherwise one have to attend nearest hospital as early as possible.
