What important side effect should be monitored when using ondansetron for chemotherapy-induced nausea?

When administering ondansetron for chemotherapy-induced nausea, one of the important side effects to monitor is fatigue. This is particularly relevant as chemotherapy itself can cause significant fatigue, and while ondansetron is intended to alleviate nausea and vomiting, it can also contribute to feelings of tiredness.

Being aware of fatigue allows healthcare providers to differentiate between the effects of chemotherapy and those potentially exacerbated by ondansetron. Monitoring allows for timely interventions if the patient’s fatigue seems excessive or impacts their quality of life and overall treatment plan.

While other potential side effects like diarrhea, visual disturbances, and jaundice may occur with various medications, they are not the primary concerns associated with ondansetron. Diarrhea can sometimes occur as a result of certain treatments, but is generally not directly linked to ondansetron use. Visual disturbances and jaundice are also uncommon and not considered priority concerns with this medication.
