A review of published cases of Stevens-Johnson syndrome and toxic epidermal necrolysis associated with the use of acetaminophen

Abstract

Purpose

Acetaminophen (paracetamol) is a widely used analgesic and antipyretic. In several studies, its use was associated with the occurrence of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). This narrative review aimed to explore and summarise available cases of SJS/TEN suspected to be associated with acetaminophen reported in the literature.

Materials and methods

Electronic searches were conducted in PubMed/MEDLINE, Web of Science, Scopus and Serbian Citation Index (SCIndeks). Case reports or case series which reported detailed clinical description of the patients diagnosed with SJS, TEN or SJS/TEN overlap which was caused or suspected to be most likely caused by acetaminophen with available full text were included in the review.

Results

Twenty-nine publications describing a total of 36 patients which satisfied inclusion criteria were included in the review. The age of the patients ranged from 3 to 77 years (median: 32.5 years). There were 15 female (41.7%) and 15 male (41.7%) patients, while for 6 patients (16.7%) gender was not reported. TEN, SJS and SJS/TEN overlap were diagnosed in 24 (66.7%), 10 (27.8%) and 2 (5.6%) patients, respectively. Reported time from the first dose of acetaminophen to the onset of the first symptoms of SJS/TEN ranged from promptly to 21 days, with a median of 3 days. Use of some form of supportive and symptomatic care was reported in 28 patients (77.8%). Systemic corticosteroids were reported to be administered in 25 patients (69.4%) and intravenous immunoglobulin in 16 patients (44.4%). All patients survived. Long-term consequences (sequelae) were reported in 5 patients (13.9%).

Conclusions

Clinicians should be aware that SJS/TEN may be an adverse effect of acetaminophen and keep in mind that its prompt recognition and withdrawal of the culprit drug along with supportive care is of utmost importance.
