In case of food allergic reactions, the treatment methods are as follows: 1. Oral anti-allergic drugs are the basic anti-allergic treatment. If the condition is not severe, one anti-allergic drug can be chosen for oral administration, such as loratadine, cetirizine, epalmatine, etc. If the condition is slightly severe, two anti-allergic drugs with different structures can be chosen for combined application. 2. For patients with severe food allergy, systematic application of glucocorticoids, such as intravenous infusion or intramuscular injection, can be chosen. If life-threatening symptoms such as respiratory distress and anaphylaxis occur, the doctor will take a series of resuscitation measures to minimize the degree of harm; 3. Clarifying the allergenic food is an important task. Clarifying the food that caused the allergy and avoiding re-intake is an important part of avoiding another food allergy. It is best if you can recall exactly what you ate that caused the allergy, but if you are not sure, you can also choose to go to the hospital for laboratory tests to help speculate on the foods you may be allergic to, or look for allergens by keeping a life diary. There are mild and severe food allergies, and going to the hospital is the safest way to go. Doctors will choose a treatment plan based on the severity of the condition, so don’t cause serious consequences and unnecessary damage due to carelessness.
