Abstract:
Dronedarone is a new antiarrhythmic drug for the treatment of nonpermanent atrial fibrillation. Compared with amiodarone, it is regarded as a safe medication due to its structural differences. In this report, we describe a 56-year-old man who developed photosensitivity due to dronedarone. He presented with itchy skin rashes for 1 week. Maculopapular exanthema was localized on the neck, both arms, and both hands, with sparing of the other parts of the body. Dronedarone was prescribed 4 weeks ago when atrial fibrillation occurred. After development of skin rashes, dronedarone was discontinued, and systemic steroid, antihistamine, and topical corticosteroid were administered for 1 week, with improvement in skin rashes. The photopatch test was performed with antiarrhythmic drugs, including dronedarone, amiodarone, and flecainide, 4 weeks after withdrawal of dronedarone. Positive reactions were recorded only to dronedarone at the site exposed to ultraviolet A. He was diagnosed with dronedarone-induced photosensitivity and advised to change the antiarrhythmic medication to others. There have been a few case reports on photosensitivity reactions due to dronedarone, which were diagnosed only by clinical suspicion. However, we suspected photosensitivity and proved it by the photopatch test. Photosensitivity should be considered in patients having skin rashes on the exposed area and taking antiarrhythmic medication, including dronedarone.
