A 3-Day Fire Ant Rush Immunotherapy Schedule: A 7-Year Experience in Songklanagarind Hospital

There are many schedules for fire ant (FA) subcutaneous immunotherapy. The rush immunotherapy (RIT) schedule is more convenient for the patients and provides faster induction of clinical protection from future stings. In this study, we sought to describe the safety and efficacy of the FA RIT and identify the risk factors for systemic reactions (SRs) during the RIT and subsequent stings.
