We conducted a single-centre, retrospective cohort study in Spain, between January 2015 and December 2021 to determine the drug survival of metformin at 12 months in people with HS in a real-world setting. We concluded that drug survival of metformin is relatively long: half the patients were still on the drug after 1 year of treatment and one in five patients were still on the drug after 2 years.engrestrictedAccessarticleCopyright OXFORD UNIV PRESS10.1093/bjd/ljad364Dermatology1365-2133
