Patient summary
Ondansetron 4mg and 8mg, as film-coated and orodispersible tablets, used for nausea and vomiting including after surgery. A 5-HT3 antagonist.
Mechanism of action
Ondansetron functions as a potent, highly selective 5-HT3 receptor antagonist. By blocking these receptors located on the vagus nerve terminals and in the chemoreceptor trigger zone of the brain, it effectively inhibits the emetogenic response to chemotherapy and surgery.
Pregnancy and breastfeeding
Pregnancy: Use of ondansetron is not routinely recommended, especially during the first trimester. Breastfeeding: Formula feeding is recommended if treatment is necessary.
Zofran contains ondansetron, a medication used to prevent nausea and vomiting, including post-operative nausea and vomiting. It is supplied as a tablet in strengths of 4mg and 8mg. This treatment is widely used for managing symptoms related to surgical recovery or medical therapies.
