SUMMARY Bullous pemphigoid is a rare complication of frusemide therapy. We present two patients in whom the link between frusemide and this condition was not recognised early, and continued frusemide therapy resulted in prolonged leg blistering and ulceration. On withdrawing the drug, all lesions in both patients resolved completely. Although uncommon, this frusemide reaction needs to be borne in mind as it can add to the morbidity of elderly patients with heart failure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
