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.1
Many factors may contribute to the occurrence and severity of nausea. These factors
include chemotherapy drug regimen, dose, schedule and route of administration.2
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 patients less than 50 years of age.3
