Abstract Nowadays, botulinum toxin Type A is used for various disease treatment with hyperactivity muscular located and cosmetic using. botulinum toxin Type A is conformed to a protein nucleus of 150 kDa associated to a complex of 6 auxiliary non-toxic proteins. In the response to chronic treatment with botulinum toxin Type A a decrease of interlude time for toxin application has been described, which can be expressed as an effect decrease of botulinum toxin Type A. Immune mechanism was identified by a search, as well as main molecules involved in development of tolerance immune versus botulinum toxin Type A. Systematic research was performed in data bases as: Pubmed, Scielo, Imbiomed. Basics and clinical research articles published after 2000 were consulted. Focusing in publications with 4 or less years since their publication. The reduction of periodicity of dosage of BoNTA is induced by immune tolerance, it is principally mediated by major histocompatibility, antigen CD19 and interleukin-6. The immune tolerance induce an increases of dosage required for establish an effective treatment with botulinum toxin Type A; however, this does not mean a botulinum toxin dependence. Development of immune tolerance to treatments with BoNTA induces a low effectiveness of chronic treatment and evidence the necessity to researching new treatments that reduce the immune tolerance of botulinum toxin Type A. Meaning an effectivity reduces of a treatment to chronic diseases.
