Latex allergy is a major problem worldwide due to both the severity of the symptomatology it produces and the risk groups that are exposed to it. Complete avoidance is difficult, if not impossible, due to its ubiquity. Natural rubber latex (NRL) is a natural polymer that is released by the Hevea brasiliensis (Hev b) tree, which functions as a protective sealant. It is currently used for the manufacture of health-care products such as tube caps, pistons, masks, and cannulas. The purpose of this review is to highlight the epidemiological, clinical, and diagnostic aspects of NRL allergy, and to conduct a review of the literature on its management through a bibliographic search of articles in databases such as PubMed, Cochrane, UpToDate, and Google Scholar, up to September 2021. About 121 articles were reviewed, of which 76 were used as a reference. We concluded that latex allergy is an entity for which its treatment, even nowadays, is avoidance, despite having a worldwide prevalence of 4.3 % and representing a surgical complication in about 20 % of surgeries with an anaphylactic reaction and a mortality rate that can reach 9 %. The only treatment that could modify the evolution of this disease is immunotherapy, but there are no standardized extracts yet and it has not been possible to determine the safest and most effective way to apply it.
