Reported Adverse Reactions

• Contact dermatitis (irritant or allergic)
• Urticaria (hives)
• Erythema, pruritus, edema

• Photosensitivity reactions (if gel residue + UV)
• Folliculitis, acneiform eruptions
• Rare: chemical burns from contaminated/expired gel

Prevention & Management

• Use hypoallergenic, fragrance-free, sterile gel.
• Wipe thoroughly post-exam; cleanse with mild soap/water.
