Ondansetron, sold under the brand name Zofran among others, is a medication used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy, migraines or surgery.[9] It is also effective for treating gastroenteritis.[10][11] It can be given orally (by mouth), intramuscularly (injection into a muscle), or intravenously (injection into a vein).[9]

Common side effects include diarrhea, constipation, headache, sleepiness, and itchiness.[9] Serious side effects include QT prolongation and severe allergic reaction.[9] It appears to be safe during pregnancy but has not been well studied in this group.[9] It is a serotonin 5-HT3 receptor antagonist.[9] It does not have any effect on dopamine receptors or muscarinic acetylcholine receptors.[12]

Ondansetron was patented in 1984 and approved for medical use in 1990.[13] It is on the World Health Organization's List of Essential Medicines.[14] It is available as a generic medication.[9] In 2021, it was the 79th most commonly prescribed medication in the United States, with more than 8 million prescriptions.[15][16]
