If an allergic reaction occurs after eating crab, take the following measures immediately:
1. Stop consumption: Once allergic symptoms are noticed, discontinue eating crab and any other foods that may cause an allergic reaction.
2. Monitor symptoms: If symptoms are mild, such as localized itching or mild hives, try increasing fluid intake to promote metabolism, which usually helps alleviate symptoms within one to two days. Taking vitamin C may also aid in recovery. If symptoms are severe, such as intense whole-body itching, prominent rashes, or accompanied by diarrhea or angioedema (vascular swelling), seek medical attention immediately.
3. Use antihistamines: If the allergic reaction is only mild, you may try over-the-counter antihistamine medications, such as chlorpheniramine or loratadine, to relieve symptoms.
4. Seek medical treatment: A physician may administer corticosteroids or epinephrine to control symptoms and may recommend allergy testing to identify the allergen, helping to avoid future exposure.
In the future, avoid eating crab and other foods that may cause allergic reactions. When dining out, clearly inform the server about your food allergies. If in doubt, consult a healthcare professional.
