Goal: Discuss the consequences of the COVID-19 pandemic for psychiatric patients already diagnosed and also later identified with obsessive-compulsive disorder, seeking to show if and when there was a worsening of their symptoms. Method: Bibliographic review developed in the months of October and November 2022. The searches were carried out through searches in the PubMed and SciELO databases. The descriptors "obsessive-compulsive disorders", "COVID-19 pandemic", "mental disorders" were used. A total of 1059 articles were found. After applying the inclusion and exclusion criteria, 16 articles were selected. Discussion: OCD is a disorder marked by obsessions and compulsions. Despite the different opinions in the literature about how such restrictions and new norms of conduct may have affected individuals with OCD, panic symptoms and even suicidal ideation were found to be a common complaint during this period among patients with psychiatric conditions with a relative worsening of its symptomatology. Final Considerations: It can be concluded, therefore, that the COVID-19 pandemic was a factor that negatively influenced those with a pre-existing diagnosis of OCD and caused the development of this pathology by a large part of the population.
