Introduction:

drug reactions with eosinophilia and systemic symptoms, known as DRESS syndrome, are a hypersensitivity reaction to medications which can lead to skin lesions and internal organ involvement. This syndrome has typically been associated with a wide variety of medications, including aromatic anticonvulsants, allopurinol and antibiotics as the main culprits.

Objective:

we present the case of a patient with DRESS syndrome secondary to losartan, manifesting skin symptoms and mild hepatic involvement. Up until now, there have been no reports of losartan as the cause of this condition. Prompt treatment was instated including the withdrawal of the offending medication and initiation of oral systemic steroids, with a satisfactory response.

Conclusion:

caregivers should be alert to the appearance of skin lesions with the use of different groups of medications, not just those typically reported, since any medication could potentially cause a hypersensitivity reaction. (Acta Med Colomb 2021; 46. DOI:https://doi.org/10.36104/amc.2021.2081).
