Introduction
In general, if an allergic reaction to eating crabs occurs, measures such as stopping crab consumption, inducing vomiting and rinsing the mouth, increasing water intake, medication, and seeking medical attention should be taken. If a severe allergic reaction occurs, such as symptoms like throat swelling and difficulty breathing, it is recommended to seek immediate hospital treatment. Under a doctor's guidance, endotracheal intubation may be performed as part of the treatment.
Generally, if an allergic reaction occurs after eating crab, measures such as stopping crab consumption, inducing vomiting and rinsing the mouth, increasing water intake, medication, and seeking medical treatment should be taken. The details are as follows:
1. Stop Eating Crab
Immediately stop eating crab once allergic symptoms are detected to avoid worsening of the allergic reaction.
2. Induce Vomiting and Rinse the Mouth
If the allergic reaction is mild and the crab was consumed recently, consider using a tongue depressor or clean chopsticks to press the base of the tongue to induce vomiting, helping expel the ingested crab from the body quickly. At the same time, rinse the mouth with water to remove any remaining crab particles.
3. Increase Water Intake
Drink an appropriate amount of warm water to promote metabolism and accelerate the elimination of allergens from the body, thereby alleviating symptoms.
4. Medication
If symptoms such as skin itching and swelling occur, topical medications such as calamine lotion, clobetasol propionate cream, or loratadine capsules may be used according to medical advice.
5. Seek Medical Attention
If a severe allergic reaction occurs, such as throat swelling or difficulty breathing, it is recommended to seek immediate medical attention. Under a doctor's guidance, endotracheal intubation might be performed, which involves inserting a tracheal tube through the mouth or nose into the patient's trachea to assist breathing.
People who are known to be allergic to crab should avoid consuming crab and any food that may contain crab ingredients.
