Is a comparison guide for common medications used for side-effect management, such as constipation, nausea, anxiety, etc. that includes a cost comparison available? —Name withheld on request
Nausea and vomiting is a common side effect of cancer treatment. Chemotherapy-induced nausea and vomiting (CINV) is a challenging side effect to manage, especially when patients are treated in the outpatient setting or CINV manifests as a late or anticipatory effect. The list below presents information on medications indicated for managing nausea and vomiting. This list is not all-inclusive; it does not include medications indicated for pregnancy-related nausea and vomiting or motion sickness. Future installments of this chart will present information on other side-effect management medications. —The editors
