What Is the Best Anti-Nausea Medication after Surgery or Chemotherapy?

January 30, 2021

Nausea and vomiting can be powerful symptoms after surgery and chemotherapy, because a molecule known as serotonin reaches a receptor in the intestines, causing patients a great deal of misery. One of the most effective anti-nausea medications is Zofran (ondansetron) which was  developed to solve this problem. Zofran is available as tablets, dissolvable tablets, strips, or liquid.

Dose of Zofran for Nausea

  • 4-8 mg It is taken by mouth every 6 hours, as needed

While it is safe for the general population, it is so effective, that it is also used in patients undergoing chemotherapy. patients take one 8 mg tablet 30 minutes before the beginning of treatment, then every 12 hours for 1 to 2 days afterward. After surgery patients are given Zofran intravenously.

Note that Zofran is not effective for motion sickness, because this problem is caused by a different mechanism. It also is not recommended anymore as a routine use of nausea during pregnancy.
