PEBC MCQ Self-care & Minor Ailments question: ointment (a mid-to-high potency steroid)

PEBC MCQSelf-care & Minor Ailments

A parent asks to use her own betamethasone valerate 0.1% ointment (a mid-to-high potency steroid) on her 2 year old's eczema on the face and in the diaper area. Which of the following is the best advice?

a. Use it under a plastic diaper to increase absorption
b. Mix it with zinc paste and use it at every diaper change
c. Avoid it there; use a low-potency steroid and regular moisturiser
d. Use it twice daily until the skin is clear, however long it takes

Show the answer and explanation

Answer: c. Avoid it there; use a low-potency steroid and regular moisturiser

Facial and diaper-area skin is thin and occlusion by diapers increases absorption, so potent steroids risk atrophy and systemic effects in young children. Low-potency steroids (such as hydrocortisone 0.5-1%) for short periods, generous emollients and trigger avoidance are appropriate, with medical review if eczema is extensive or not improving. Sharing another person's prescription is also inappropriate.

Common mistake

Using potent topical steroids on infant face or under occlusion.
