The first phase of chemotherapy-induced nausea and vomiting (CINV) is referred to as acute CINV.1
Acute CINV occurs within the first 24 hours following chemotherapy administration, with the highest risk period occurring during the first 4 hours of treatment.2 Many factors determine how nausea occurs and how severe it will be. These factors include drug, dose, schedule of administration and route.3
In addition, acute CINV is more likely to occur in cancer patients who have experienced nausea and vomiting after previous chemotherapy sessions, in females, in patients who drink little or no alcohol, and in younger patients.3
