Chemotherapy Nausea and Vomiting  

What is CINV?

A side effect of chemotherapy

Chemotherapy often has side effects. One of them is chemotherapy-induced nausea and vomiting, otherwise referred to as CINV.

Chemotherapy can bring on CINV by:

  • Injuring stomach cells that start the process of nausea and vomiting
  • Directly activating the area of the brain responsible for producing nausea and vomiting

Several chemotherapies can cause CINV in both ways.

Chemotherapy-Induced Nausea and Vomiting (CINV)CINV

There are 2 main types of CINV:

  • Acute: Within the first 24 hours of receiving chemotherapy
  • Delayed: From Day 2 up to Day 5 after chemotherapy

The amount and timing of CINV can vary. Some chemotherapies cause acute nausea and vomiting. Others cause acute nausea and vomiting followed by another period of delayed nausea and vomiting.

Chemotherapy is essential in your fight against cancer. However, the nausea and vomiting that often go along with it are something that you can help prevent by adding EMEND. Now is the time to speak to your health care team about how a regimen with EMEND can help prevent CINV.

EMEND is used in adults to prevent nausea and vomiting caused by certain anticancer medicines. EMEND is always used with other medicines.

EMEND is not used to treat nausea and vomiting that you already have.

EMEND should not be used continuously for a long time (chronic use).
