Dermatological Reactions to CGM Adhesives

Common Reactions

CGM adhesives can cause various skin reactions in users.

Types of Reactions

Mechanical Irritation

• Not a true allergic reaction

Contact Dermatitis

• Irritant type: Direct skin irritation from chemicals
• Allergic type: Immune-mediated delayed reaction

ISOBORNYL ACRYLATE (IBOA) Sensitivity

Some adhesives contain IBOA, a known sensitizer that can cause delayed allergic reactions.

Risk Factors

• Apply topical corticosteroids for inflammation
• Consult dermatologist for persistent issues

Alternatives

• Request alternative adhesive formulations from manufacturer
• Try different CGM brands if reactions persist
• Explore barrier film options

Manufacturer Efforts

CGM companies are actively developing:

• Hypoallergenic adhesive options
• Alternative materials
• Shorter-wear sensors to reduce exposure time
