Upsides
  • Zofran (ondansetron) comes in many different forms that you don't have to swallow, such as a film that goes on the tongue or a dissolving pill.
  • Zofran (ondansetron) is fast-acting and starts working within 30 minutes.
  • Unlike some other nausea medicines, the side effects for Zofran (ondansetron) are relatively mild.
  • Transderm-Scop (scopolamine) is well tolerated.
  • Prevents nausea for 3 days.
  • Because Transderm-Scop (scopolamine) is a skin patch, it's a good alternative to stopping nausea and vomiting if you're not able to swallow pills.
Downsides
  • Zofran (ondansetron) doesn't treat nausea and vomiting that's already happening. It only works to prevent future episodes.
  • High doses of Zofran (ondansetron) can cause problems with heart rhythm if you're at risk.
  • If you are also taking antidepressants, you are at higher risk of developing a dangerous condition called serotonin syndrome. Talk with your doctor about your risks.
  • Can only be used for prevention of nausea and vomiting. It can't stop nausea or vomiting that's already happening.
  • The side effects can be worse if you are 65 and older.
  • You might feel sleepy, drowsy, or have blurry vision while taking Transderm-Scop (scopolamine). Taking alcohol or other medicines that make you drowsy can make this effect worse.
  • You're more likely to have heat stroke or feel dehydrated.
  • It takes a few hours for Transderm-Scop (scopolamine) to kick in, so you have to remember to take it beforehand.
