Those who are at risk of anaphylaxis should be supplied with an EpiPen and counselled, along with their close relatives, responsible adults, or carers, about how and when to use it.In hospital, Advanced Life Support (ALS) protocols should be followed.Adrenaline (eg, EpiPen®) should be administered if available for anyone with signs of shock, breathing difficulty, or airway swelling.If a bee or wasp sting causes a severe reaction or anaphylaxis, urgent medical attention should be sought.
