Overview

Adverse drug reactions may occur in up to 10% of the worldwide population, and also affect up to 20% of patients who are hospitalized. Of all the cases of fatalities caused by anaphylaxis, drugs may be responsible for 20% of the deaths. The incidence of toxic epidermal necrolysis is about 0.4-1.2 cases per million in a year.

Immediate hypersensitivity are over-reported and few patient reporting these have reactions on careful testing.[1][2]
