Objectives: The objective was to characterise and identify potential risk factors for intolerance to multi-drug leprosy therapy (MDT) which prompted a medication change in a leprosy referral centre in northeastern Brazil.
Design: A retrospective chart review of leprosy patients treated at a state referral centre for leprosy in Natal, Rio Grande do Norte, Brazil was completed. Chart review focus was on adverse effects necessitating modification of MDT regimen.
