Contact Dermatitis due to Exelon Patch applied at the Wrong Site

Contact Dermatitis due to Exelon Patch applied at the Wrong Site

This photo is from an elderly woman with newly diagnosed Alzheimer’s disease. Exelon (rivastigmine) patch was prescribed. However, upon follow-up, a coin-shaped itchy erythematous patch was found over the right anterior tibial region. On further questioning, it was found that the patient has wrongly applied the patch onto her lower limb (usually it should be applied onto the trunk, back or arm). Exelon patch was stopped and the patient was prescribed with topical synalar cream 0.0125% for the contact dermatitis. The patient was prescribed with Aricept (donepezil) in replacement of the Exelon patch and her relatives were advised to closely supervise her medication usage.
