CINV Risk Factors
Patient-specific risk factors and therapy-specific risk factors will play a role in whether you
experience nausea and vomiting. It is important to remember that not all people undergoing
chemotherapy experience nausea and vomiting.
Patient-Specific
Risk Factors
You may experience CINV if:
- you are younger than age 50
- you are female
- you had nausea and vomiting during
previous chemotherapy treatments
- you experienced sweating, dizziness,
or warmth after your last chemotherapy treatment
In addition, nausea and vomiting are actually
less likely to affect people who have a history
of chronic alcohol use over many years.

Therapy-Specific
Risk Factors
The dose and the way chemotherapy drugs are given can affect your potential for experiencing CINV:
- Higher doses of chemotherapy are
more likely to cause CINV
-
Your treatment schedule, which is the time of day and how often you take the drug, may
cause CINV. For example, chemotherapy given in the morning is more likely to cause
CINV. Treatments given at short intervals - one treatment close to another - are more
likely to cause CINV since there is less time to recover from the nausea and vomiting.
-
A chemotherapy drug injected into a vein (intravenously) may cause CINV sooner than
a drug given by mouth (orally), or injected into a muscle because it is absorbed more
quickly into the bloodstream.
If you are receiving both chemotherapy and radiation therapy, you may be at higher risk of experiencing nausea and vomiting.
