What should I do if my skin itches due to an allergic reaction to eating shrimp?

If a patient experiences allergic symptoms such as itchy skin after eating shrimp, they should stop consuming shrimp and any other foods that might worsen the allergy. If symptoms have just appeared and are mild, drinking plenty of water may help enhance metabolism and facilitate the elimination of allergens from the body. Gently clean the skin with lukewarm water to relieve discomfort, but avoid using irritating bath products. Refrain from scratching the skin to prevent breaks that could lead to infection. Oral antihistamines such as loratadine or cetirizine hydrochloride may help alleviate allergic symptoms; however, consultation with a doctor or pharmacist is recommended before taking any medication, especially for special populations such as pregnant women, breastfeeding mothers, and children.

If skin itching is severe, accompanied by redness, swelling, rashes, or other symptoms such as shortness of breath or abdominal pain, immediate medical attention at a hospital is necessary.
