Yes, there are three commonly known types of CINV: acute, delayed, and anticipatory. Acute CINV occurs on the same day as chemotherapy treatment, especially within the first 4-16 hours. Delayed CINV occurs on the days following chemotherapy, usually within 24-72 hours. Anticipatory CINV occurs in people who experienced uncontrolled nausea and vomiting with other cancer treatments. It may happen before you start a new cycle of treatment and can be triggered by certain smells, tastes, objects, or images that you associate with chemotherapy.
