Could an Eczema Medicine Cause Contact Allergy? Questions About Topical Steroids

If a prescribed eczema treatment seems to make a rash worse or the same areas never improve, tell the prescriber. Irritation, infection, an incorrect diagnosis, difficulty following a regimen and contact allergy are among several possibilities. A worsening rash does not automatically mean steroid withdrawal or allergy.

What is contact allergy to a steroid?

Allergic contact dermatitis is a delayed immune reaction that can occur to an active ingredient or another ingredient in a product. The clinician can look at timing, location and every product used. A prospective study patch-tested 80 people with atopic dermatitis and 80 without it using selected corticosteroid markers. Its results show why the particular test panel, formulation and timing of readings can matter. They do not establish the rate of steroid allergy in all people with eczema.

Prepare for a useful review

• Bring the actual tubes and full ingredient lists, including over-the-counter products.
• Record when each was started and where it was applied; take dated photographs if comfortable.
• Ask whether specialist patch testing is appropriate and whether the suspected ingredient is included.
• Follow the clinician's advice about treatment changes; do not abruptly stop a long-used medicine based on this article.
