Friday Dr Q&A with Dr Liew – Allergic Reactions

Dr Liew Woei Kang

Marcie, who inspired MarcieMom to start this blog, doesn’t have any allergy and thus, this blog has been focused on eczema. Recognizing that there are many parents whose child also have allergy, MarcieMom invites Dr Liew Woei Kang, Paediatrician with special interest in Allergy, Immunology & Rheumatology to share more about managing allergy for eczema children.

More about Dr Liew: Dr. Liew practices at the SBCC Baby & Child Clinic and is also a visiting consultant to KK Hospital. He was also awarded several research grants from the National Medical Research Council, Singhealth Foundation and KKH Research centre to pursue clinical research in paediatric anaphylaxis, drug allergy, primary immunodeficiencies and Kawasaki disease. He is also the President of Singapore’s Asthma & Allergy Association which is currently administering the very first eczema fund (initiated by MarcieMom’s donation) for low income patients in Singapore.

MarcieMom: How can a parent recognize an allergic reaction and more importantly, which are the symptoms that are signs of serious reaction such as anaphylaxis? When should a parent prepare an epi-pen and how can the parent teach the child and the alternative care-giver on when an epi-pen is to be used?

Mild to moderate allergic reaction include:

• Swelling of lips, face, eyes

• Hives or welts

• Tingling mouth

• Abdominal pain, vomiting

Antihistamines usually suffice.

Severe allergic reaction (anaphylaxis) include:

• Difficult/noisy breathing

• Swelling of tongue

• Swelling/tightness in throat

• Difficulty talking and/or hoarse voice

• Wheeze or persistent cough

• Persistent dizziness or collapse

• Pale and floppy (young children)

Epipen should be administered for severe reactions. A written anaphylaxis plan should be provided with pictorial reminders on how to administer an epipen.

MarcieMom: Thank you Dr Liew, next week we’ll learn more on outdoor allergen.
