Case study shows barrier patches effectively reduce contact dermatitis from CGM use, suggesting a treatment option.
The popularity of continuous glucose monitoring (CGM) devices rises, similar to the prevalence of CGM-related contact dermatitis. There is still a paucity of recommendations for its treatment, and here, we documented the use of barrier patches from adhesive dressing tape. A 25-year-old type I diabetic presented symptoms of contact dermatitis after a month of CGM use. A barrier patch significantly prevented its symptoms. CGM was discontinued for over a year, and after it was reintroduced, the symptoms relapsed. Barrier patches were used again, with good results. We added some data on the management of CGM-related contact dermatitis and materials suitable for barrier patches.
