Pregnancy Interaction

• Be careful when using it during pregnancy.
• There aren't many research on humans, but the evidence we do have doesn't reveal a big risk to the fetus.
• Should only be taken if the benefits are greater than the risks, especially in the first trimester.
• Ondansetron is usually the best choice for vomiting during pregnancy because there is more evidence for it.
• Not sure if it gets into breast milk a lot, so only use it while breastfeeding with appropriate medical supervision.

 How It Works

• Granisetron is a specific blocker of the 5-HT3 receptor.
• How it works:
• Chemotherapy and radiation make a lot of serotonin to be released.
• Serotonin activates 5-HT3 receptors in the brain and intestines, which makes you throw up.
• Granisetron stops these receptors from working, which stops nausea and vomiting quite well.
