What is a common adverse effect of Ondansetron?

Ondansetron is a medication primarily used to prevent nausea and vomiting, especially in patients undergoing chemotherapy or surgery. One of the common adverse effects associated with Ondansetron is headache and flushing. These symptoms can occur due to the drug's action on serotonin receptors, which might influence vascular dynamics and lead to increased blood flow and subsequent flushing for some individuals.

Headaches are particularly reported in patients using Ondansetron as the medication can affect central nervous system pathways. Flushing, a sudden reddening of the face or neck, can also occur as a vascular response to the drug. Therefore, recognizing headache and flushing as common side effects is important for monitoring patient responses to Ondansetron and managing any discomfort that may arise during treatment.
