Acute liver failure and self-medication.

Introduction: Not responsible self-medication refers to drug use in high doses without rational indication and often associated with alcohol abuse. It can lead to liver damage and drug interactions, and may cause liver failure.

Aim: To warn about how the practice of self-medication can be responsible for acute liver failure.

Method: Were used the Medline via PubMed, Cochrane Library, SciELO and Lilacs, and additional information on institutional sites of interest crossing the headings acute liver failure [tiab] AND acetaminophen [tiab]; self-medication [tiab] AND acetaminophen [tiab]; acute liver failure [tiab] AND dietary supplements [tiab]; self-medication [tiab] AND liver failure [tiab] and self-medication [tiab] AND green tea [tiab]. In Lilacs and SciELO used the descriptor self medication in Portuguese and Spanish. From total surveyed were selected 27 articles and five sites specifically related to the purpose of this review.

Conclusions: Legislation and supervision disabled and information inaccessible to people, favors the emergence of cases of liver failure drug in many countries. In the list of released drugs that deserve more attention and care, are some herbal medicines used for the purpose of weight loss, and acetaminophen. It is recommended that institutes of health intensify supervision and better orient their populations on drug seemingly harmless, limiting the sale of products or requiring a prescription for release them.
