Nifurtimox, sold under the brand name Lampit, is a medication used to treat Chagas disease and sleeping sickness.[2][4] For sleeping sickness it is used together with eflornithine in nifurtimox-eflornithine combination treatment.[4] In Chagas disease it is a second-line option to benznidazole.[5] It is given by mouth.[2]

Common side effects include abdominal pain, headache, nausea, and weight loss.[2] There are concerns from animal studies that it may increase the risk of cancer but these concerns have not been found in human trials.[5] Nifurtimox is not recommended in pregnancy or in those with significant kidney or liver problems.[5] It is a type of nitrofuran.[5]

Nifurtimox came into medication use in 1965.[5] It is on the World Health Organization's List of Essential Medicines.[4] It is not available commercially in Canada.[2] It was approved for medical use in the United States in August 2020.[3] In regions of the world where the disease is common nifurtimox is provided for free by the World Health Organization (WHO).[6]
