Clozapine-induced angioneurotic edema.

Many prescribed drugs can cause cutaneous rashes and eruptions, which may present in various forms and severity. Most of these reactions are mild; however, the severe cases can lead to life-threatening complications. The most severe of these reactions may include angioedema, acute generalized exanthematous reactions, Stevens-Johnson syndrome and toxic epidermal necrolysis. We report two cases wherein the patients developed classical angioneurotic edema on clozapine therapy and improved rapidly when clozapine was stopped.
