well defined lesions occurring in the same sites each time the offending drug is taken. FDE typically
presents 30 min to 8 h after drug exposure. An extensive list of medications are known to cause FDE and
finding the underlying drug help in proper management of cases.
Aim: To study and analyse the causes and clinical pattern of FDE.

Assam. A total of 50 cases of FDE were studied. Cases of FDEs encountered between July 2018 to June
2019 during routine pharmacovigilance activities were analyzed.
Result: Among 50 patients, 34 were male and 16 were female. Majority of patient were between the age of
18-40 years, mean age being 33.4 years. In 31 cases there was previous history of drug intake. Commonly
affected sites include genitals and lips, palms and soles followed by extremities and other sites.
