After a hornet sting, the patient should apply water, dilute acetic acid or alcohol, or iodophor for local wound irrigation, which can dilute and neutralize the toxin, anti-inflammatory and antibacterial effects. Patients should go to a regular hospital if possible, because they should let the doctor remove the bee stings from the wound. If not removed, the stinger remains a foreign body that cannot be digested and absorbed by the body, and can cause repeated allergic inflammatory reactions. After the removal of the bee stings, patients can first apply antihistamines orally, such as loratadine, cetirizine, paracetamol, and ibastine tablets. At the same time, glucocorticoids with calcium gluconate can be applied intravenously to relieve the local allergic inflammatory reaction. Patients should be observed in the hospital for a period of time, because some patients with sensitive constitution may also lead to more serious allergic inflammatory reactions.
