Pancrelipase-Induced Hypersensitivity Reaction: Case Report and Review of Literature.

INTRODUCTION: Drug-induced exanthems are commonly associated with NSAIDs, antibiotics, and anti-epileptics. Pancrelipase is frequently used for conditions resulting in pancreatic exocrine insufficiency. Published case reports of pancrelipase hypersensitivity focus on the respiratory manifestations. CASE REPORT: Here we report a case of skin hypersensitivity resulting from pancrelipase use. To further assess this association, we used a Naranjo nomogram, which determines the likelihood that an adverse drug reaction is the result of the drug itself. Our patient had a score of seven, suggesting our patient had a probably adverse drug reaction. DISCUSSION: As pancrelipase is a commonly prescribed drug, clinicians should be aware of the potential hypersensitivity skin reactions associated with pancrelipase.
