Key takeaways
Bonjesta (doxylamine/pyridoxine) and Zofran (ondansetron) are both medications used to treat nausea and vomiting, but they are used in different situations. Bonjesta is specifically FDA-approved for morning sickness during pregnancy, while Zofran is approved for preventing nausea and vomiting after surgery or cancer treatments. Bonjesta combines an antihistamine (doxylamine) and a dietary supplement (pyridoxine, or vitamin B6), whereas Zofran is an antiemetic that works by blocking serotonin in the brain. Bonjesta is taken as a tablet, typically once or twice a day, and does not have a generic version available. Zofran, on the other hand, is available in multiple forms, including tablets, orally disintegrating tablets, and injections, and it does have a generic version. Common side effects of Bonjesta include sleepiness, while Zofran can cause headaches and fatigue. Additionally, Zofran has potential interactions with medications that affect serotonin levels, which can lead to a serious condition called serotonin syndrome.
