Allergic reactions to insect bites and stings

Pain, redness, itching and swelling confined around the site differ from breathing difficulty, throat swelling, faintness or symptoms affecting several body areas. The latter pattern may be anaphylaxis.

A local reaction develops at or near the bite or sting and can become quite uncomfortable without being anaphylaxis. A systemic allergic reaction involves areas away from the site and may affect breathing, circulation, the skin or the digestive system. Anaphylaxis can present with airway swelling, wheeze, collapse, marked dizziness or rapidly developing symptoms across the body.

Redness that spreads gradually with increasing warmth, tenderness, pus or fever may indicate cellulitis rather than allergy. Scratching broken skin can raise the chance of infection, so the pattern over time matters.

Move away from the insects. If a visible stinger remains, remove it promptly without delaying care; avoid squeezing an attached venom sac. Wash the area, apply a wrapped cold pack and elevate the affected limb when practical. Do not scratch, cut or suck the site.

A pharmacist can advise about an oral antihistamine, soothing skin treatment or pain relief for a local reaction, taking age, pregnancy, medical history and other medicines into account. Someone prescribed an adrenaline auto-injector should use it immediately when their emergency plan indicates, call emergency services and lie down with legs raised unless breathing is harder in that position. A second dose should be used only as directed in the person’s plan or by emergency professionals.

Call emergency services now for trouble breathing, a hoarse voice, tongue or throat swelling, collapse, confusion, severe dizziness, or widespread hives accompanied by other symptoms. Do not wait to see whether these features settle, and do not let the person stand or walk.

Obtain prompt medical advice for a sting inside the mouth or near the eye, extensive swelling, repeated vomiting, worsening pain, spreading redness, pus or fever. After a suspected systemic reaction, clinical follow-up can confirm the likely insect, review auto-injector technique and create an avoidance and emergency plan.

Describe the insect if known, where the exposure occurred, how quickly each symptom appeared and which treatment was given. Ask whether specialist allergy assessment is appropriate, whether adrenaline auto-injectors are needed, how they should be stored in UAE heat and which symptoms should trigger their use.
