Herein, we report three new separate cases of human envenomations by Micrurus hemprichii for the Amazon, which is a biome where envenomations by Micrurus are seldom reported. Two women were bitten after stepping on the snakes and one man was bitten while handling the animal. All cases occurred in the peridomicile, in rural areas. The first case evolved mainly to local symptoms, but the patient was discharged before the identification of the snake and had to be called back for observation before being eventually discharged. In the second case, the patient presented transitory dyspnea and she was discharged after four days in hospital. In the third case, the patient showed only local symptoms, but he was about to receive unnecessary antivenom against coral snakes. Cases like these show the importance of educational problems regarding local venomous snakes in order to avoid bites and to provide the correct hospital treatment. For this, trained professionals in cases involving venomous animals are needed. Copyright © 2023 Elsevier Ltd. All rights reserved.
