Anaphylaxis in infants

A baby cannot describe throat tightness, dizziness, or nausea. Caregivers may instead notice difficult or noisy breathing, wheezing, persistent cough, tongue swelling, repeated vomiting, drooling, a weak cry, sudden sleepiness, limpness, mottled skin, or unusual distress. Hives and facial swelling may occur, but their absence does not exclude anaphylaxis.

Some infant behaviours, such as crying or spitting up, have many possible causes. Concern rises when a change begins suddenly after a possible allergen and is accompanied by breathing trouble, swelling, pallor, limpness, or rapid deterioration. The urgency comes from these red-flag features, not from guessing which trigger is most common.

If the baby has a prescribed adrenaline device and the action plan indicates anaphylaxis, use it immediately in the outer thigh and call UAE ambulance services. Hold the infant flat rather than upright over a shoulder. If breathing is difficult, the baby may be supported with the legs outstretched. Do not offer food, drink, or oral medicine during breathing distress.

Device selection and dosing depend on the infant’s clinical assessment, so use only the product prescribed for that child and learn its technique in advance. Keep the written plan with the medicine, make sure every caregiver can find it, and check storage and expiry information regularly.

Seek emergency help for sudden noisy or difficult breathing, tongue or throat swelling, persistent wheeze or cough, collapse, unresponsiveness, or a baby who becomes pale and floppy after a possible exposure. Administer prescribed adrenaline according to the plan without waiting for a rash. If the infant is unresponsive and not breathing normally, begin age-appropriate resuscitation while help is coming.

Discuss which signs are specific enough to activate the plan, exactly how to position the baby, who should carry the device, and whether nursery staff need training. Ask whether the suspected food or medicine should be avoided before specialist review and how feeding can continue safely without unnecessary restriction.
