Are you feeling queasy? Nausea and vomiting are uncomfortable but common symptoms that can be caused by illness, gastrointestinal issues, cancer treatments, medication side effects, anesthesia, and pregnancy. When over-the-counter (OTC) remedies don’t cut it, your healthcare provider may prescribe Zofran (<\/span>ondansetron<\/span><\/a>), a medication used to <\/span>treat<\/span><\/a> upset stomach and prevent vomiting—especially when caused by chemotherapy, radiation therapy, and surgery. It’s also can be used off-label to treat morning sickness during pregnancy.<\/span><\/p>\n

Zofran belongs to a class of drugs called <\/span>antiemetics<\/span><\/a>, which work by blocking certain chemical receptors in the body that can trigger nausea. Though the brand name Zofran is no longer available, the generic is still widely used. It provides quick relief, alleviating nausea and vomiting in about 30 minutes. Zofran’s exact onset of action may vary depending on factors such as the dosage administered and various patient-specific factors.<\/span><\/p>\n

How long does Zofran take to work? <\/span><\/h2>\n

Zofran typically begins to work within 30 minutes to two hours, says <\/span>Sazan Sylejmani, Pharm.D.<\/span><\/a>, owner and pharmacy manager at <\/span>Westmont Pharmacy<\/span><\/a> in Illinois. Within that time frame, you can expect a significant reduction in nausea and vomiting.<\/span><\/p>\n

The dosage form impacts how long Zofran takes to kick in. “For instance, the orally disintegrating tablet (ODT) might act faster due to its sublingual absorption, while the oral tablet might take a bit longer as it has to pass through the digestive system,” says Dr. Sylejmani.<\/span><\/p>\n

“Zofran ODT or ondansetron ODT has a rapid onset of action, with its peak antiemetic effect within 15-30 minutes,” explains <\/span>Robert Glatter, MD<\/span><\/a>, a board-certified emergency medicine physician at <\/span>Lenox Hill Hospital<\/span><\/a> in New York. Higher doses of Zofran may work more efficiently to relieve and prevent nausea and vomiting in the same time frame.<\/span><\/p>\n
