While providing superior benefits for a cadre of diverse diseases, the prevalence of Immunosuppressive use often brings to question possible additional risks caused by these therapies in the setting of surgical procedures. Specifically, is the risk of impaired wound healing or increased chance of infection worth avoiding the possible side effects associated with temporary cessation during the perioperative period. The appropriate use of immunosuppressants (IS) during elective surgery has been debated extensively with conflicting results, through the current body of literature. Herein, we aim to provide a comprehensive, yet streamlined, overview of the common IS medications that surgeons are likely to encounter in practice in a wide variety of patients. This discussion includes an overview of the pharmacology and use of eight of the common IS medications: azathioprine, cyclosporine, hydroxychloroquine, infliximab, leflunomide, methotrexate, methylprednisolone, and mercaptopurine.
