Zofran is an antiemetic medication used to prevent nausea and vomiting that may be caused by surgery, cancer chemotherapy or radiation therapy. Its active ingredient is ondansetron hydrochloride.

Zofran can be administered intravenously or intramuscularly and is available in various dosages. It is considered effective and well-tolerated, although like all medications it may cause side effects in some individuals.

Zofran, which contains ondansetron, can be administered intravenously or intramuscularly by a healthcare professional at a hospital or clinic to prevent nausea and vomiting caused by chemotherapy. The first dose is usually given 30 minutes before chemotherapy starts, with additional doses given 4 and 8 hours later if necessary. If ondansetron is being used for surgery, it will typically be given just before the procedure. In some cases, ondansetron may be given after surgery to treat nausea and vomiting if it was not given before the surgery. Zofran is available in syrup form for intravenous or intramuscular administration.
