Dermatol Ther. 2020 Nov;33(6):e13826. doi: 10.1111/dth.13826. Epub 2020 Jul 5.

Abstract

Sildenafil is one of the commonest over the counter drugs which is orally taken by the people for sexual enhancement. It is an inhibitor of phosphodiesterase type 5 (PDE5) and results in engorgement of carpora cavernosa and help in erectile dysfunction. There are fewer adverse cutaneous drug reactions reported by sildenafil perhaps due to use of the drug without medical prescription. Here we are reporting a case of sildenafil induced hypersensitivity syndrome that is possibly the first one and reviewing the medical literature on type of adverse cutaneous drug eruption due to sildenafil and other PDE5 inhibitors.

Keywords: drug reaction; inflammatory disorders; pharmacology; pruritus; therapysystemic.
